Well, you know which one is the first to come to mind...

Carnotaurus

A genus of Abellosaurid theropod dinosaur that lived in South America during the Late Cretaceous period, between 69 and 66 million years ago. The only species is Carnotaurus sastrei. Known from a single well-preserved skeleton, it is one of the best-understood theropods from the Southern Hemisphere. T Carnotaurus is a derived member of the Abelisauridae, a group of large theropods that occupied the large predatorial niche in the southern landmasses of Gondwana during the late Cretaceous.

Aucasaurus

A genus of medium-sized abelisaurid theropod dinosaur from Argentina that lived during the Late Cretaceous (Santonian to Campanian stage) of the Anacleto Formation. It was smaller than the related Carnotaurus, although more derived in some ways, such as its extremely reduced arms and almost total lack of fingers...

Quilmesaurus

A genus of carnivorous theropoddinosaur from the Upper Cretaceous (Campanian to Maastrichtianstages) Allen Formation of Argentina. It was a member of Abelisauridae, closely related to genera such as Carnotaurus. The only known remains of this genus are leg bones which share certain similarities to a variety of abelisaurids. However, these bones lack unique features, which may render Quilmesaurus a nomen vanum (more commonly known as a nomen dubium, or "dubious name")...

CARNOTAURUS SASTREI

TORO CANIVORO EN HONOR A SASTRE

Lo más notable de este dinosaurio son sus dos pequeños cuernos sobre los ojos en su pequeña cabeza, siendo el primer carnívoro que mostrara cuernos bien formados y definidos. También se hallaron impresiones de la piel que presentaban pequeños osteodermos (escudos óseos) distribuidos aleatoriamente por los laterales del cuerpo.

Los hábitos alimenticios de Carnotaurus aún no están claros, algunos estudios sugieren que el animal era capaz de cazar presas grandes, como los saurópodos pequeños que habitaban hacia el final del Cretácico; otros estudios encontraron que se alimentaba principalmente de animales relativamente pequeños.

En esta recreación se puede una pareja que muestra dimorfismo sexual. El rojo es el macho, con cuernos más grandes y de mayor corpulencia. La hembra alerta cuida sus huevos que se incuban en un nido de arena al sol

HABITÓ: Chubut (Patagonia Argentina)

HACE: 70 millones de años (Cretácico)

ES UN: Terópodo, Abelisáurido

MEDÍA: 9 m de largo x 3 m de altura

PESABA: 2 toneladas

Sketch Assortment I’ve made of the fauna of the Campanian-aged (approx. 83–74.5 mya) Anacleto Formation of Patagonia, which is famous for the Auca Mahuevo nesting site where hundreds of titanosaurs came to lay their eggs in shallow pits which they dug with their hind feet and left for the hatchlings to fend for themselves.
