Coahuilaceratops magnacuerna is a genus of ceratopsian dinosaur that lived during the Late Cretaceous period, approximately 72 to 66 million years ago. It was discovered in the Cerro del Pueblo Formation in the state of Coahuila, Mexico, from which it derives its name.
The Coahuilaceratops was a herbivorous dinosaur that belonged to the ceratopsid family, known for its characteristic horns and a large bony plate on its neck. Although a complete skeleton has not been found, the fossil remains discovered so far have allowed paleontologists to get an idea of its appearance and size.
It is estimated that the Coahuilaceratops measured around 8 meters in length and weighed 4-5 tons. It had a large and strongly built skull, with a series of horns and ornamentation on its head. It had a pair of short horns over its eyes and a longer pair in the area of its nose, similar to other ceratopsians.
A distinctive feature of Coahuilaceratops is a large fan-shaped bony plate that projected upward from the back of the skull. This plate had wavy edges and probably served a defensive or visual display function for intraspecific communication.
Although not many details about its behavior are known, it is believed that the Coahuilaceratops lived in herds and fed on low plants, using its shovel-shaped bill to uproot and crush vegetation. It probably shared its habitat with other herbivorous and predatory dinosaurs, such as Tyrannosaurus rex.
