In terms of size, Monolophosaurus jiangi was a medium-sized theropod compared to some of its larger relatives. It is estimated that it reached a length of around 5 to 6 meters (approximately 16 to 20 feet) from head to tail. It had an agile body structure and strong hind legs indicating that it was a fast and active terrestrial predator.
The name "Monolophosaurus" is derived from a distinctive feature of this dinosaur: a crest on the top of its skull. This crest, often called the "sagittal crest," consists of a simple bony ridge that runs the length of the skull from the nose to the back of the head. This feature gives this dinosaur its name, which roughly translates to "single-crested lizard."
The head of Monolophosaurus was equipped with sharp, serrated teeth, indicative of its carnivorous diet. It is believed to have fed on a variety of prey, including other dinosaurs and possibly small reptiles and mammals.
This dinosaur lived in what is now China and fossils have been found in the Lower Shaximiao Formation of Sichuan province. The discovery of Monolophosaurus jiangi fossils has provided valuable information about theropod diversity in the Early Jurassic of China and has contributed to our understanding of the evolution of these dinosaurs in this region.
Approximate measurements of the Monolophosaurus:
