Late Cretaceous, 83-66 million years ago
Secernosaurus, meaning “severed lizard,” is a genus of herbivorous dinosaur that lived during the Late Cretaceous period, about 83-66 million years ago. Its fossils have been found in Argentina, and it is known from several well-preserved specimens.
Secernosaurus was a small to medium-sized dinosaur that measured up to 4 meters (13 feet) in length and weighed around 150-200 kilograms (330-440 pounds). It had a long, slender body with a long neck and tail, and long, powerful legs. It is thought to have been a fast runner and agile predator.
Secernosaurus had a relatively small head with a beak-like mouth and numerous teeth, suggesting that it may have been an omnivore, feeding on both plant and animal matter. It also had sharp claws on its hands and feet, which it may have used for defense or to catch prey.
Secernosaurus is an important dinosaur because it is one of the few known theropods from the Late Cretaceous period in South America. Its fossils have provided important insights into the evolution and biogeography of theropod dinosaurs in the southern hemisphere.
Overall, Secernosaurus is a fascinating dinosaur that has contributed to our understanding of the diversity and ecology of theropod dinosaurs during the Late Cretaceous period in South America.
