[D] Palaeosaurus sternbergii
Fitzinger, 1840 / Geoffroy Saint-Hilare, 1833
Not considered dinosaur
In 1840 Fitzinger described a partial fossil reptile skeleton, found by him in 1833 in the collection of the Prague National Museum, under the name Palaeosaurus sternbergii: a new genus and new species. Fitzinger was most probably not aware that this name was already used by others.
Palaeosaurus Riley & Stutchbury, 1836 and Paleosaurus Riley & Stutchbury, 1840, Palaeosaurus Geoffroy Saint-Hilaire, 1833, the generic name that preoccupies both Palaeosaurus Riley & Stutchbury, 1836 and Fitzinger, 1840 (and is now a junior subjective synonym of the crocodyliform genus Aeolodon).
