Ceratopsians

Ceratopsians were a group of herbivorous dinosaurs from the Cretaceous period, famous for their beaked mouths, bony neck frills, and, in many species, horns on the face. They ranged from small, lightly built early forms to large, heavily built quadrupedal species such as Triceratops, and their skulls were specialized for cropping and grinding tough vegetation. Many later ceratopsians likely used their horns and frills for defense, display, and species recognition, and some may have lived in herds based on bone-bed evidence.

 Aguja formation

The Aguja Formation is a Late Cretaceous geological formation exposed in West Texas (USA) and parts of northern Mexico. It consists mainly of sandstones and shales, with some lignite and mudstone, deposited in environments ranging from marine and deltaic to inland floodplain. The formation records the retreat of the Western Interior Seaway and features rich fossil deposits, including dinosaurs, turtles, and fossil plants such as palms. It is particularly well exposed in Big Bend National Park and is notable for its complex stratigraphy and diverse terrestrial vertebrate fauna.
