Scandensia ciervensis (Evans and Barbadillo 1998) Early Cretaceous~130 mya ~7 cm skull length was orginally considered a sister to living squamates (Iguania + Scleroglossa). Here we add the Tritosauria to that list. This key basal lepidosaur taxon was derived from a sister to Gephyrosaurus and Sophineta.
Distinct from Gephyrosaurus, the skull of Scandensia had a larger orbit and smaller rostrum with a larger naris. The tail was gracile. The ventral pelvis was deeper. Tendril-like digits with trenchant claws mark Scandensia as an arboreal climber. It had lightly-built vertebrae and thick ribs.
Evans and Barbadillo marked Scandensia as "unusual" because they want to fit it into the existing framework of squamates. And it doesn't quite fit! When they recognize the Tritosauria, they will find Scandensia is not so unusual after all.
