 Abstract 

Prognathodes thanatos, new species, is described on the basis of the holotype from Mozambique, Africa. The new species is readily distinguished from congeners in having the following combination of live coloration details and morphological characters: head and body silvery white with three broad, dark brown bands; pelvic fin including spine black; dorsal-fin rays XIII,19; anal-fin rays III,15; lateral line short and incomplete with 26–29 pored scales; gill rakers 4 + 12–13 = 16–17; snout length 12.6% SL; and angle of preopercle finely serrate. The new species appears to be most closely related to Prognathodes guyotensis, a poorly known, deepwater species of butterflyfish known from very few specimens. The assignment of both species to the genus Prognathodes is accompanied by a critical reassessment and discussion of the currently inadequate definition of the genus.

Abstract

A new species of Calamaria is described from the Tenasserim Range, Ratchaburi Province, western Thailand based on morphological and molecular evidence. Calamaria flavicollaris sp. nov. can be distinguished from its congeners by the combination of the following morphological characters: 1) rostral scale wider than high; 2) portion of rostral scale visible from above greater than the half the length of the prefrontal suture; 3) prefrontal length shorter than frontal length, not entering orbit and in contact with first two supralabials; 4) five or six scales surrounding paraparietal scale; 5) preocular and postocular present; 6) four supralabials, the second and third in contact with the eyes; 7) eye diameter smaller than eye-mouth distance; 8) five infralabials, the first pair separating the mental scale from anterior chin shields; 9) seven modified maxillary teeth; 10) 180 ventral scales with three preventral scales; 11) 13 divided subcaudal scales; 12) cloacal plate single; 13) tail relatively short (4.5% of the total length), tapering, gradually to a pointed tail tip; 14) dorsum dark brown with eleven dark longitudinal stripes; 15) ventral surface yellow with a median line of dark flecks on underside of tail; and 16) dark collar followed by yellow ring at nuchal region. Genetically, the new species exhibits a pairwise distance of ≥17.56% from all other congeners based on the mitochondrial cytochrome b gene fragment. Furthermore, we provide cranial osteological description of the new species based on micro-CT scanning. Calamaria flavicollaris sp. nov. is currently known only from the type locality and represents the fourth species of the genus recorded for Thailand.

Diagnosis. Calamaria flavicollaris sp. nov. can be distinguished from all other congeners by the following combination of characters (Tables 3, 4; Suppl. Table 1): 1) rostral scale wider than high; 2) portion of rostral scale visible from above greater than the half the length of the prefrontal suture; 3) prefrontal length shorter than frontal length, not entering orbit, and in contact first two supralabials; 4) five or six scales surrounding the paraparietal scale; 5) preocular and postocular present; 6) four supralabials, the second and third in contact the eyes; 7) eye diameter smaller than eye-mouth distance; 8) five infralabials, the first pair separating the mental scale from anterior chin shields; 9) seven modified maxillary teeth; 10) 180 ventral scales with three preventral scales; 11) 13 divided subcaudal scales; 12) cloacal plate single; 13) tail relatively short (4.5% of the total length), tapering, gradually to a pointed tail tip; 14) dorsum dark brown with eleven dark longitudinal stripes; 15) ventral surface yellow with a median line of dark flecks on underside of tail; and 16) a dark nuchal collar followed by a yellow ring along neck.

Four Calamaria species in Thailand:
A Calamaria flavicollaris sp. nov. from Suan Phueng District, Ratchaburi Province B C. lumbricoidea from Than To District, Yala Province
C C. schlegeli from Betong District, Yala Province D C. pavimentata from Kaeng Hang Maeo District, Chanthaburi Province 

Photos by Parinya Pawangkhanant (A–C) and Attapol Rujirawan (D)

Etymology. The specific epithet flavicollaris is derived from the Latin words “flavo” (yellow), “collare” (collar or neck), and the suffix “-aris”, which refers to the appearance of the yellow nuchal ring of this species. 

We suggested an English common name “Tenasserim Collared Reed Snake” and the Thai common name “งูพงอ้อบ่วงบาศ” (Ngu Phong O Buang Bat) for this species.

Abstract

Theropod dinosaur remains from the Barremian (Lower Cretaceous) Wessex Formation of the Isle of Wight, UK, are rare and often fragmentary. Here, we present a previously undescribed braincase from this formation that represents a new coelurosaurian, Invictibellatrix amberina gen. et sp. nov. Phylogenetic analysis and comparative anatomy indicate that Invictibellatrix is distantly related to all previously named theropods from this stratigraphic unit. Theropod braincases are often regarded as morphologically and phylogenetically conservative, but we demonstrate that neurocranial characters provide essential data that can help clarify the phylogenetic relationships of theropods. The sub-circular occipital condyle, sub-oval foramen magnum and presence of a sagittal nuchal crest indicate that Invictibellatrix is referable to Megaraptora, with phylogenetic analyses recovering it as an early-diverging member of this clade, within a paraphyletic array of Eurasian taxa. Incorporation of Invictibellatrix into a biogeographical analysis suggests that non-megaraptorid megaraptorans likely had a cosmopolitan distribution in the Early Cretaceous, and that the absence of megaraptorans in the Late Cretaceous of Laurasia is best explained by regional extinction. The recognition of this new genus increases our knowledge of Early Cretaceous European coelurosaurian diversity, which now includes tyrannosauroids, maniraptoriforms and megaraptorans.

Invictibellatrix amberina gen. et sp. nov.

Etymology: the generic name Invictibellatrix is derived from the Latin ‘invictus’ (‘unconquered’) and ‘bellatrix’ (‘warrior’ in the feminine form) and honours the future role of Megaraptora as Gondwanan apex predators, while early on in their evolutionary history they were smaller, non-apex predators [55–57]. This name is to give hope and strength to all those who are bullied, discriminated, victimized and oppressed that tomorrow will be theirs and not to give up in the face of such odds. The species epithet amberina is derived from the amber present in the plant debris beds of the Wessex Formation [58].

Locality and horizon: Sudmoor Point, near Brook, southwestern coast of the Isle of Wight, UK; Wessex Formation, Barremian, Lower Cretaceous. Most likely from the lower plant debris beds (L1 to L5).

Holotype: NHMUK PV R6775, a partial braincase.

Diagnosis: Invictibellatrix amberina can be diagnosed by the following unique character combination (autapomorphies marked with an asterisk): (i) *presence of a small basipterygoid recess anterior to the anterior tympanic recess (ATR) on each side of the parabasisphenoid, (ii) *slightly transversely compressed, hourglass-shaped nuchal crest, (iii) the presence of two large, deep and dorsoventrally elongate paracondylar recesses on the ventrolateral sides of the basioccipital, and (iv) *parasagittal nuchal crest recesses that are slightly curved and pronounced.

It lived in what was likely a seasonally wet-to-dry floodplain environment and is surrounded by other dinosaurs including large long-necked rebbachisaurid sauropods (directly behind Invictibellatrix, center) and relatives of Iguanodon (right). A spinosaurid theropod, potentially the apex predator of the time, fishes (left). Invictibellatrix has just caught and is consuming two small mammals. Gymnosperms dominate the environment as flowering plants (angiosperms) were not common at this time. Other reptiles including relatives of modern lizards, crocodiles and turtles enjoy the warm Early Cretaceous weather of the U.K.

 Abstract

The origin and early diversification of birds remain highly debated in vertebrate evolution. Although estimates of the evolutionary timescales suggest a Jurassic period radiation, a profound scarcity of fossils from this period has hampered how the distinctive bird bauplan was assembled. Selection for powered flight has been viewed as the primary driver of early avialan skeletal modifications, attesting to the independent occurrences of aerodynamic features among paravian lineages. Here we report on the discovery of a Late Jurassic avialan, Yuezhuornis yangyuanensis, gen. et sp. nov., from the Zhenghe Fauna of southeastern China. As one of the earliest diverging avialans, Y. yangyuanensis exhibits a striking mosaic of features, combining a mixture of avialan- and troodontid-like cranial characters, paired with derived postcranial traits and a deinonychosaur-like hyperextensible second pedal digit. Phylogenetically informed analyses show that Y. yangyuanensis possesses markedly short forelimbs—a condition present widely among non-avialan theropods. These findings provide strong evidence for a terrestrial, flightless lifestyle of Y. yangyuanensis. Our study demonstrates that evolution works intensively as exemplified by the occurrence of several, divergent ecological pathways being exploited in the initial diversification of birds.

Abstract

Baobab trees (Adansonia) are iconic members of Madagascar's biota that serve as emblems for the island's unique biodiversity. Despite this recognition, many questions remain regarding evolutionary relationships and species limits within the genus. We used custom-designed targeted sequence capture data to obtain phased allelic sequences for hundreds of nuclear loci and plastomes. Using broad geographic sampling, representing all species in the genus, and including a few possible hybrid individuals, we reconstructed the population history of Malagasy baobabs using network inference methods to detect reticulation. We obtained a species tree that is well supported, but with clear cases of reticulation, most notably admixture between Adansonia rubrostipa and A. madagascariensis in northwestern Madagascar, and instances of introgression involving the widespread species, A. za. Analysis of exclusivity factors suggests elevating one variety of A. za to the species rank, and also raises the possibility, pending additional sampling, of splitting A. rubrostipa into two species. We discuss the implications of gene flow on species delimitation and diversification in the context of conservation efforts for these iconic and threatened trees. Given our results, we formally resurrect the species A. bozy from A. za var. bozy, thus raising the number of endemic Malagasy baobab species from six to seven.

Abstract

A new genus and species of tooth-plated lungfishes, Dianodipterus huizeensis gen. et sp. nov., is described from the Qujing Formation (late Eifelian, Middle Devonian) of Huize County, Qujing, north-eastern Yunnan, China. It differs from other lungfishes in the small proportion of the tooth-bearing part on the pterygoid (less than one-quarter), the extensively developed anteromedial edentulous portion of the pterygoid, and tooth rows few in number (only four). Phylogenetic analysis reveals that Dianodipterus is more plesiomorphic than Dipterus, yet crownward of Melanognathus. As the ninth Devonian lungfish genus from China, the new taxon displays a novel schema of lungfish dentition and increases the diversity of early lungfishes.

Abstract

Musa dulongjiangensis (Musaceae), a new species of the genus Musa endemic to Yunnan, southwestern China, is described and illustrated in this study. This new species is morphologically similar to M. puspanjaliae, but can be clearly distinguished by a combination of morphological characters. Its female bud bracts are dark purple externally and purple internally, with 6–7 basal female flowers arranged in two rows; the base of the compound tepal bears distinct and dense red stripes, the ovary is pale green and glabrous. The male bud bracts are consistent in color with female bracts, dark purple externally and purple internally, and are non-revolute before abscission. Each bract bears approximately twenty male flowers arranged in two rows, with pinkish-purple anther lobes. The fruit bunch is lax, consisting of upward-curving fruits. Typically, each bunch possesses eight hands, with 6–7 fruits per hand, and the pedicels are obviously developed.

ABSTRACT

Primula octopoda W.B.Ju & Q.Huang, a new species of Primula (Primulaceae) in sect. Aleuritia, is herein described and illustrated from Batang County, Sichuan Province, southwestern China. Morphologically, P. octopoda is most similar to P. stenocalyx, but it can be readily distinguished by its dwarf habit, the presence of stolons 2–7 cm in length ending in small rosettes occasionally bearing a single flower, elliptic to broadly obovate leaf blades, a very short or absent scape bearing one or two flowers, and a smaller, annulate corolla with a prominent yellow eye. The complete chloroplast genome of P. octopoda spans 154,164 bp with a GC content of 36.97% and contains 125 genes. Phylogenetic analyses using plastid and ITS data both place P. octopoda within sect. Aleuritia while supporting its distinct species status. Given the current lack of adequate information on its population size and geographic range, the species is provisionally assigned a status of Data Deficient (DD) according to the IUCN Red List criteria.

Primula octopoda W.B.Ju & Q.Huang, sp. nov. 

Diagnosis. The new species most closely resembles P. stenocalyx, sharing narrowly lanceolate bracts, a tubular calyx with similarly divided oblong or lanceolate lobes, stamens and style included within the corolla tube, and an oblong capsule. However, it differs in its shorter stature, the presence of 2–7 cm long stolons each ending in a small rosette and occasionally bearing a solitary flower, elliptic to broadly obovate leaves, a scape up to 2 cm long or absent with 1–2 flowers, and an annulate corolla with a yellow eye and smaller flowers (Figures 2 and 3).

Etymology. The specific epithet of the new species refers to its distinctive feature of producing multiple stout, fleshy stolons that resemble the tentacles of an octopus; hence the name octopoda, which vividly reflects the plant's numerous stolons extending like “eight legs.”

Vernacular Name. Chinese mandarin: “bā táng fĕn bào chūn” (巴塘粉报春), meaning “Batang Farinose Primrose” in English.

Abstract

A well-preserved sarcopterygian fish skull from the Famennian (Upper Devonian) Shogrãm Formation, of the Chitral region, northern Pakistan, is described. Collected as a calcareous nodule by J.A. Talent and colleagues, it has been investigated using high-resolution computed tomography to reveal the internal cranial architecture. It represents a new genus and species of tooth-plated, cosmine-covered dipnoan (lungfish), Talentichthys kuragh n. gen. n. sp., distinguished from all previously described Devonian dipnoans by its deep nasal notches, elongate narrow subnasal ridge, and uniquely shaped olfactory cavities. Additional specimens from the type locality, showing additional aspects of morphology, will be necessary to clarify the phylogenetic position of the new form within the Dipnoi.

Family Holodontidae Gorizdro-Kulczyzka, 1950

Genus Talentichthys n. gen.

Etymology: The generic name commemorates Professor John Talent, with -ichthys (Gk) for fish.

 

Diagnosis: A tooth-plated, cosmine-covered dipnoan with deep notches for the anterior (incurrent) nares, elongate subnasal ridges, and the nasal cavity subdivided dorsally into a posteromesial reniform recess, and an anterolateral subdivision elongated rostrocaudally that extends as a groove to the nasal notch.

Remarks: The new taxon is represented by only one incomplete anterior skull portion, which displays nasal notches in the upper mouth margin, a long and deep nasal groove, prominent subnasal ridge and a pterygoid tooth plate. These features demonstrate dipnoan affinity, and are not consistent with porolepiforms, the other major dipnomorph subgroup, in which cosmine-covered forms are predominantly of Early Devonian age. We provisionally refer Talentichthys n. gen. to the family Holodontidae, based on the updated diagnosis and comprehensive review of the family provided by Long (2010). Although very incomplete, our new taxon displays features not shown in any previously described dipnoan. Further material from the Karakoram type area (currently inaccessible) will clarify the relationships of the new taxon.

Talentichthys kuragh n. gen. n. sp.

Etymology: The specific epithet is the local term ‘Kurãgh’ from the name of the stratigraphic section of Talent et al. (1999) which produced the specimen.

 

Locality and horizon: Collected from about 63 m above the base of the Kurãgh Spur stratigraphic section of Talent et al. (1999), about 55 km northeast of Chitral, northern Pakistan (Fig. 1), within the Upper Devonian (Famennian) Shogrãm Formation.

Holotype: ANU V3736, the only known specimen (ANU Department of Materials Physics, Research School of Physics, Canberra).

Abstract

We describe Yipetalichthys maxiongensis gen. et sp. nov., a quasipetalichthyid placoderm from the Eifelian Shangshuanghe Formation (Qujing, Yunnan, China). High-resolution micro-CT reveals an endocranium bearing cranial nerve grooves and inner ear structures. The dermal neck joint permits a quantitative character, the angle between the ventral laminar ridge (v.l.r) and the skull-roof midline. Current specimens yield two non-overlapping bins (state 0: ≤15°; state 1: ≥28°), separating Macropetalichthyidae and Quasipetalichthyidae; the 15–28° interval is unsampled and the threshold remains testable with new material. Expanded parsimony analysis, adding Yipetalichthys and six additional ptyctodont taxa, recovers Petalichthyida as sister to Ptyctodontida and places Yipetalichthys within Quasipetalichthyidae. The diagnosis includes large unenclosed elliptical orbits, slender unbifid postorbital processes, an elongate occipital region, and a shallow posterolateral vagus canal. Yipetalichthys shows a high v.l.r angle, supporting its quasipetalichthyid placement and providing a reproducible metric for future comparisons across articulated specimens. Our analysis of the neck joint helps to clarify petalichthyid phylogeny and identifies distinct, recurring architectures among major placoderm groups: in Antiarcha, a reverse sliding joint; in Petalichthyida, an elaborate sliding joint guided by the ventral laminar ridge with laminar cranial articular facets forming a longitudinal sliding track opposing the articular flanges of the anterior dorsolateral plate (ADL); in Ptyctodontida, a sliding joint with spoon-shaped cranial articular facets opposing ADL articular flanges; in Actinolepidoidei, a simple sliding condition; in Brachythoraci, a ginglymoid joint. These distinct neck joint architectures demonstrate the high evolutionary plasticity of this structure and its multiple, independent pathways toward cranial mobility in placoderms.

 ABSTRACT

Tyrannosaurid species have often been considered to have high longevity and low diversity relative to contemporaneous megaherbivores. Recent chronospecies assertions around tyrannosaurid lineage evolution have reinforced this idea. An albertosaurine, Tromerosaurus solumons, from the Oldman Formation of Alberta, Canada, shares features with Daspletosaurus and Gorgosaurus, and prompts reassessment of tyrannosaurid characteristics and the Late Cretaceous radiation of Tyrannosauridae. Maxillary morphometrics reveal clear intermediate morphologies in Tromerosaurus between Daspletosaurus and Gorgosaurus, including an anteroposteriorly longer maxillary fenestra and narrower pila promaxillaris than in Gorgosaurus libratus. An anatomical diagnosis of Tromerosaurus solumons allowed referral of specimens previously attributed to Gorgosaurus. Restricted stratigraphic overlap between Tromerosaurus and Gorgosaurus offers support to this distinction. A modified recent character-taxon dataset recovers Tromerosaurus as the earliest diverging member of Albertosaurinae under parsimony or Tyrannosaurinae under Bayesian inference. The difference in topologies along with reduced node support values for clades such as Lythronax + Teratophoneus, or Bistahieversor and other derived tyrannosaurines, suggests uncertainty as to their recovery within Albertosaurinae or Tyrannosaurinae. Together, these results support a younger divergence of the two main tyrannosaurid lineages with rapid character acquisition and transition during the Late Cretaceous (Santonian–Maastrichtian).

Etymology—The genus name derives from Ancient Greek for terrible or frightful (tromerós) lizard (saûros) with regard to the taxon having a mosaic of characteristics between Gorgosaurus (terrible lizard) and Daspletosaurus (frightful lizard). The specific epithet (solumons) derives from Latin for lonely (solus) and mountain (mons), pertaining to the isolation of the lacrimal horn by a broad flat shelf of the posterior process of the lacrimal. This also pays homage to the infamous fictional dragon Smaug (in particular, to his lair in The Hobbit (Tolkien, 1937), recognizing the visual similarities between tyrannosaurids and iconography of dragons.
