Thanos (named after the well known Marvel villain) is an extinct genus of carnivorous brachyrostan abelisaurid dinosaur that lived in Brazil during the Santonian stage of the late Cretaceous Period. It contains only a single species, T. simonattoi, which is also the type species.

The length of Thanos has been estimated at grow as much as; 5.5 to 6.5 meters (18–21 feet), making it a medium-sized theropod.

Despite the incompleteness of the material, a number of diagnostic features are present; a well-developed keel becoming wider and deeper posteriorly on the ventral surface; two lateral small foramina separated by a relatively wide wall on each lateral surface of the centrum; and well-developed and deep Prezygapophyseal Spinodiapophyseal fossae. In view of these features, Thanos species seem to be more derived than other abelisaurids at the time.

Thanos shared its environment with an undescribed larger theropod believed to be a Megaraptoran of which a vertebra, specimen MPMA 08–0003/94, has been found at Ibira. This would imply that Thanos was likely not the apex and/or dominant predator of its habitat.


In Thanos' phylogenetic analysis, Delcourt and Lori (2018) recovered Thanos in a large polytomy with other Brachyrostrans within the Abelisauridae.
