Extract

Acteosaurus crassicostatus Calligaris, 1993 was erected based on a partial skeleton of a small lizard found in marine carbonate rocks from the Cretaceous (Upper Cenomanian-Lower Turonian) of Comen, Slovenia. Here, we show that the holotype and only known specimen cannot be assigned to the genus Acteosaurus (Calligaris, 1993), but instead is referable to and indistinguishable from Adriosaurus suessi Seeley, 1881. Acteosaurus crassicostatus is therefore a junior objective synonym of Adriosaurus suessi.
