Tijubina pontei (Bonfim and Marques 1997) was a tiny Early Cretaceous lizard from the Crato Formation (late Aptian) of northeast Brazil. In a recent redescription Simões (2012) reported Tijubina lacked the posteroventral and posterodorsal processes of the dentary and the tibial/fibular length equaled the femoral length. The posterior dentary teeth were robust, cylindrically based, unsculptured and bore no cuspids. Simoes (2012) nested Tijubina in a basal position among the Squamata. Reynoso (1998) reported a similar nesting for Huehuecuetzpalli. Neither considered the possibility that both specimens nested in a third squamate clade, the Tritosauria, outside of the Iguania + Scleroglossa, as they do here.
Tijubina was derived from a sister to the Early Permian Lacertulus and Huehuecuetzpalli is more derived within the Tritosauria.
Tijubina is distinguished by its teeth, which are larger posteriorly and shaped like cylinders instead of sharp points. Tijubina was much smaller than either Lacertulus or Huehuecuetzpalli.
Simoes (2012) described Tijubina as immature due to a imcompletely calcified joints, a wide open sternal fontanelle (hole), unfused pectoral and pelvic elements. Simoes did not realize that adult tritosaurs are likewise incompletely calcified. Unlike Huehuecuetzpalli, and despite its smaller size, the carpal elements of Tijubina were well ossified.
The pes of Tijubina had tendril-like toes, indicating an arboreal lifestyle. The tarsals were not coossified, a trait typical of many (but not all) tritosaurs.
Bolet and Evans described new material (LH 20523) they thought belonged to Scandensia, but that specimen nests with Tijubina.
