Clarification

This page needs clarification. The type species of Streptospondylus von Meyer, 1832 is S. altdorfensis von Meyer, 1832, and S. cuvieri is not synoymous with altdorfensis, nor is it synonymous with Eusteptospondylus (Allain, 2001). The four other species of Streptospondylus, S. grandis, S. rostromajor, S. recentior, and S. meyeri, should be removed from this page, as they are synonymous with Iguanodon anglicus.

Streptospondylus major

Delair (1966) considered Streptospondylus major to be a valid species of Iguanodon, as Iguanodon major, but his proposal has gone unnoticed in the literature except Naish and Martill (2008). However, it should be noted that the original description of Streptospondylus major by Owen (1842) was based not only on a cervical from Cuckfield, West Sussex but also similar cervicals from Brook Point and Culver Cliff on the Isle of Wight. However, such remains are sparse to uphold Streptospondylus major as a synonym of Iguanodon, so Streptospondylus major is probably a nomen dubium referrable to Iguanodontia indet.

Streptospondylus meyeri is based on an isolated cervical (or anterior dorsal) from Brook Point, Isle of Wight (Owen 1854). However, this species has remained unstudied since Owen (1854) and the taxonomic status of S. meyeri has not yet been determined, but is probably a nomen dubium since one vertebrae is not sufficient grounds for establishing a new species.

Streptospondylus grandis is a nomen nudum because Hulke (1879) does not provide a description.
