Jeanie Buss Younger: Pentaceratops: The Five-Horned Face of the Late Cretaceous
Pentaceratops, meaning 'five-horned face,' was a large, herbivorous ceratopsian dinosaur from the Late Cretaceous Period. Despite its name suggesting five horns, it actually possessed fewer, yet still impressive cranial features that distinguished it among its contemporaries.

THE ESSENTIAL BRIEF
Overview of Pentaceratops
Pentaceratops is a genus of ceratopsid dinosaur known for its distinctive skull with multiple horns and a large frill. First discovered in 1921, the type species, Pentaceratops sternbergii, was formally described in 1923. It lived during the Late Cretaceous Period, approximately 65 to 75 million years ago, and is primarily known from fossil sites in North America.
Although its name translates literally to 'five-horned face,' most specimens reveal fewer horns than the literal interpretation suggests. Its robust body and elaborate head ornamentation make it a notable figure in the study of ceratopsian evolution and behavior.
