Indosaurus matleyi

Reptilia - Abelisauridae

Taxonomy
Indosaurus matleyi was named by Huene (1933) [Named by Huene in Huene & Matley 1933.]. Its type specimen is GSI K27/565, a skull, and it is a 3D body fossil. Its type locality is Bara Simla, Jabalpur [Carnosaur Bed], which is in a Maastrichtian terrestrial sandstone in the Lameta Formation of India.

It was considered a nomen dubium by Novas et al. (2010).

Diagnosis
ReferenceDiagnosis
F. Huene 1933In comparing the described fragments of the skulls of Indosuchus and Indosaurus, it becomes evident that the latter possesses much stouter and thicker bones. The parietals of Indosaurus are short and broad and Indosuchus has a narrow, parietal crest. In Indosuchus, the roof of the skull between the orbits is flat, in Indosaurus, there seems to have been a transverse crest above and behind the orbits, and the frontals are concave and decline in front; on the post-frontals there were apparently horn-like tuberosities; nothing of this is found in Indosuchus.
M. T. Carrano and S. D. Sampson 2008‘. . . much stouter and thicker bones. The parietals. . .are short and broad. . .there seems to have been a transverse crest above and behind the orbits, and the frontals are concave and decline in front; on the post-frontals there were apparently horn-like tuberosities’ (Huene & Matley 1933: 46).
