[D] Paleosaurus [ncG]
Describer
Riley & Stuchbury, 1840
Classification
Not considered dinosaur
Info
Genus
Palaeosaurus (Riley & Stuchbury, 1840) > Palaeosauriscus (Kuhn, 1959) > Palaeosaurus (Riley & Stuchbury, 1836 / Geoffroy Saint-Hilaire, 1833)
According to the JVP article (Benton, Juul, Storrs & Galton, 2000) on the systematics of Thecondontosaurus Riley & Stutchbury\\\'s use of the name Palaeosaurus in their 1836 note/abstract describing the small prosauropod Thecondontosaurus.
The generic name Palaeosaurus was used with two species, [P. cylindricum]and [P. platyodon] but , the brief note does not constitute an adequate description of either species or the genus Palaeosaurus, and these taxa must be regarded as nomina nuda in their initial appearance.
In 1837 they published a second note, in which the species names appeared as [P. cylindricum]and [P. platyodon], and the generic name appeared with two different spellings: Palaeosaurus and Paleosaurus. Only in 1840 did they at last publish a paper adequately describing the two species, under the names [Paleosaurus cylindrodon] and [Paleosaurus platyodon].
In 1842, Owen adopted the earlier spelling Palaeosaurus for this genus, and almost everybody used this spelling ever since. In 1959, however, Oskar Kuhn discovered that Palaeosaurus is preoccupied by an 1833 usage for a crocodylian and proposed the replacement name [Palaeosauriscus].
This name subsequently became widely accepted. Under present ICZN spelling rules, however, the spelling Paleosaurus may be considered distinct from the spelling Palaeosaurus, and this name, because the genus under that spelling was adequately described in the 1840 Riley & Stutchbury paper, is the correct name for this genus. Benton, Juul, Storrs & Galton then sink Palaeosaurus as preoccupied and Palaeosauriscus as a junior synonym of Paleosaurus. Source: G. Olshevsky.
