What were spinosaru?

Answer 1

Spinosaurus was a large carnivorous dinosaur that lived during the Late Cretaceous period, approximately 112 to 93 million years ago. It is known for its distinctive sail-like structure on its back, formed by elongated neural spines, and its elongated snout resembling that of modern crocodiles, suggesting it was well-adapted for a semi-aquatic lifestyle. Spinosaurus is considered one of the largest theropods, potentially exceeding the size of Tyrannosaurus rex. Fossil evidence indicates it may have preyed on fish and possibly other animals in its environment.
