Though it has been since been typically identified as an indeterminate "coelurian" theropod, Thecocoelurus was reidentified by Darren Naish and colleagues in 2001 as a member of the Oviraptorosauria, a group of omnivorous maniraptoran theropods, which would make it the only oviraptorosaur fossil that has ever been found in Europe.
He has published articles on the Wealden Supergroup theropods Thecocoelurus, Calamospondylus and Aristosuchus.

Coelurus

Coelurus fragilisCoelurus gracilisgracilis
William Davies was the first to notice the specimen and assumed a close affinity with Coelurus.
C. daviesi was named by Richard Lydekker in 1888 for Harry Seeley's Thecospondylus daviesi, a neck vertebra from the Early Cretaceous of England, but this species was later transferred to its own genus, Thecocoelurus.

Ornithomimosauria

It is paleontologically significant for being one of the first ornithomimosaur specimens known from England and represents the earliest record of Ornithomimosauria in Europe. A 2014 re-evaluation comparing the specimens with European ornithomimosaur fossils found that Thecocoelurus was likely one of the oldest known ornithomimosaurs, and a possible senior synonym of Valdoraptor.

Thecospondylus

Seeley named the fossil Thecospondylus daviesi, referring it to a genus he had named earlier for the incomplete cast of a sacrum.
