Its name means before Ceratosaurus. It was initially thought to be an ancestor of Ceratosaurs, due to the similar small crest on its snout, but this trait is now known to be characteristic of early tyrannosaurs such as Guanlong. It has become one of the earliest known members of tyrannosaurids, which fed on insects, lizards, mammals and frogs.

It is one of the most interesting and enigmatic dinosaurs of the Jurassic era.

A Discovery in England

The Proceratosaurus was discovered in Gloucestershire, England. To date, only a well-preserved skull has been found, which has provided a lot of information about this dinosaur. At the end of the snout, the base of a crest is preserved. Although the apex of the skull is missing, preventing a complete understanding of the shape of this crest, it is believed to be similar to that of Guanlong, extending in the form of a true crest along the length of the skull.

Mistaken Identity and Revision

Due to its nasal horn, the Proceratosaurus was named to reflect a supposed relationship with the Ceratosaurus. However, this link was later disproved. Today, the Proceratosaurus is considered a primitive tyrannosauroid, similar to Guanlong. This reevaluation has helped scientists better understand the early evolution of tyrannosaurs.

Physical Characteristics and Diet

The Proceratosaurus is one of the earliest known members of the tyrannosaurids, making it an important link in the evolution of this group of dinosaurs. It fed on insects, lizards, small mammals, and frogs, suggesting it was an agile and opportunistic hunter. Its relatively small size and diverse diet would have made it highly adaptable to different environments.

Nasal Crest and Significance

The nasal crest of the Proceratosaurus is a notable feature. Although the full shape of this crest is not well known, its presence suggests it may have been used for display or as a visual signal to other members of its species. This crest is also one of the features that connect it to other primitive tyrannosaurs, providing clues about the evolution of these traits over time.

Habitat and Behavior

The Proceratosaurus lived in what is now England during the Middle Jurassic period. Its environment would have consisted of forests and open areas, providing an ideal habitat for a small hunter like it. Its ability to hunt a variety of prey suggests it was an adaptable predator, capable of surviving in different environmental conditions.

Curiosities about Proceratosaurus

Despite its name suggesting a link with the Ceratosaurus, the Proceratosaurus is more closely related to the early tyrannosaurs. This initial classification error underscores the importance of continuous reevaluation in paleontology. Additionally, the Proceratosaurus provides valuable insight into the early diversification of tyrannosaurs, helping scientists trace how these iconic creatures evolved.
