[Paleontology] Ornithodesmus cluniculus Seeley, 1887 | 'bird link' • theropod dinosaur from the Lower Cretaceous of the Isle of Wight, England


Ornithodesmus cluniculus Seeley, 1887

Ornithodesmus cluniculus was first described by Harry Govier Seeley in 1887, based on a set of six fused vertebrae from the hip (sacrum), specimen number BMNH R187, found by William D. Fox in the Wessex Formation of Brook Bay. Seeley thought the bones came from a primitive bird, and gave it a name meaning "bird link", from Greek ὄρνις (ornis), "bird", en δεσμός (desmos), "link". The specific name cluniculus means "little buttock" in Latin, a reference to the small thighs indicated by the size of the specimen.
