Coloradisaurus ([Los] Colorados lizard)
José Fernando Bonaparte - 1978
Estimated 4-5 meters long
Late Triassic, 150 million years ago
Coloradisaurus is a genus of small, bipedal dinosaur that lived during the Late Jurassic period, approximately 150 million years ago. Its fossils have been found in the state of Colorado, in the United States, hence its name.
Coloradisaurus was a relatively small dinosaur, measuring about 4-5 meters in length and weighing between 100-200 kilograms. It had a long, slender tail and a lightweight body, which would have allowed it to move with agility. Its long legs and light weight structure suggest that it was a fast runner, and that it was probably able to evade predators.
One of the most distinctive features of Coloradisaurus was its large, elongated hands, which had four long fingers ending in sharp claws. These hands would have been useful for grasping and manipulating its prey. Its teeth were also elongated and serrated, suggesting that it was a carnivore.
Coloradisaurus lived during a time when the North American continent was split into two separate land masses. This led to the evolution of different species of dinosaurs on each side, and Coloradisaurus is one of the few dinosaurs that has been found on both land masses. This makes it a unique species in the dinosaur world, and provides valuable insight into the evolution of dinosaurs in North America.
Overall, Coloradisaurus is a fascinating dinosaur that provides a glimpse into the Late Jurassic period and the evolution of dinosaurs on the North American continent.
