Compsosuchus (meaning "elegant crocodile") is a dubious genus of abelisauroid dinosaur from the Late Cretaceous Lameta Formation of India.
Discovery and naming
[edit]Compsosuchus was described in 1933 by von Huene and Matley based on remains discovered between 1917 and 1919.[1] The type species is C. solus, and the type and only specimen is GSI K27/578, an axis with an articulated axial intersection. The genus is often considered a nomen dubium.[2]
Classification
[edit]Although classified as an allosaurid by Huene and Matley (1933) and Molnar et al. (1990) because of superficial similarities with the axis vertebrae of Allosaurus, a 2004 review of Lameta Formation theropods found it to be similar to members of the Abelisauridae, including Carnotaurus and Indosaurus, necessitating the placement of Compsosuchus as an abelisaurid.[3][4] While a 2011 study classified Compsosuchus as a noasaurid,[5] a 2024 study identified it as an indeterminate abelisaurid.[6]
