Jaklapallisaurus asymmetrica

Reptilia

Taxonomy
Jaklapallisaurus asymmetrica was named by Novas et al. (2011) [Small-sized basal sauropodomorph dinosaur diagnosed by the following combination of characters (autapomorphies indicated by an asterisk): distal femur with a widely transversely open popliteal fossa in distal view*; medial condyle of distal femur sub-triangular in distal view*; distal femur with straight anterior margin; distal tibia with concave posteromedial border*; and astragalar body with a straight dorsal edge in posterior view* and a medial condyle strongly developed anteriorly, with a medial end that is 1·6 times deeper than the lateral one. Furthermore, Jaklapallisaurus differs from Plateosaurus ingens in the presence of a less strongly anteroposteriorly expanded proximal tibia.]. Its type specimen is ISI R274, a set of postcrania (fragmentary ?dorsal vertebra, proximal caudal vertebra, distal right femur, right tibia and astragalus, right metatarsals II-IV, 2 pedal phalanges), and it is a 3D body fossil. Its type locality is 3 km north of Jaklapalli village (ISIR 274), which is in a Norian terrestrial horizon in the Upper Maleri Formation of India.
