CompsosuchusCompsosuchus is a dubious genus of abelisauroid theropod dinosaur from the Late Cretaceous Lameta Formation of India.Discovery and namingCompsosuchus was described in 1933 by von Huene and Charles [Alfred Matley|Matley] based on remains discovered between 1917 and 1919. 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.ClassificationAlthough classified as an allosaurid by von Huene and Matley and Molnar et al. 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. While a 2011 study classified Compsosuchus as a noasaurid, a 2024 study identified it as an indeterminate abelisaurid.
