Poekilopleuron bucklandii^[1]	Gen. et sp. nov.	Valid	Jacques Amand Eudes-Deslongchamps	Middle Jurassic (Bathonian)	Calcaire de Caen		As shown in Ref.,^[2] the genus and species were first named and described by Jacques-Amand Eudes-Deslongchamps in a report published in 1836, based on holotype material that is now destroyed. In 1837, Eudes-Deslongchamps published a more detailed account of this discovery in a monograph^[3] which was also inserted next year in volume 6 of the "Mémoires de la Société Linnéenne Normandie".^[4]
Palaeosaurus cylindrodon	Gen. et sp. nov.	Preoccupied genus, nomen dubium	Henry Riley, Samuel Stutchbury	Late Triassic, Rhaetian	Durdham Down		The name was preoccupied by a non-dinosaurian archosaur named by Geoffroy Saint-Hilaire in 1833. Palaeosaurus cylindrodon is the type species of the genus.
Palaeosaurus platyodon	Sp. nov.	Preoccupied genus, nomen dubium	Henry Riley, Samuel Stutchbury	Late Triassic, Rhaetian	Durdham Down		Second species of the preoccupied genus Palaeosaurus, later renamed into the separate genus Rileya.
Thecodontosaurus^[5]	Gen. nov.	Valid	Henry Riley, Samuel Stutchbury	Late Triassic, Rhaetian^[6]	Durdham Down		Thecodontosaurus is the fourth valid dinosaur genus named. It was first excavated by Riley and Stutchbury in 1834, and they published a preliminary description in 1835. When they assigned the remains to a new taxon, which they named Thecodontosaurus, they did not assign a species. The genus was not originally recognized as a dinosaur, with Riley and Stutchbury finding it a saurian.
