Spinosaurus (Spine lizard)
Ernst Stromer - 1915
Estimated 18 meters long
S. aegyptiacus (type)
North Africa, particularly Egypt - Bahariya Formation, and Morocco - Kem Kem Beds
Late Cretaceous, 112-93.5 million years ago
Spinosaurus is a genus of theropod dinosaur that lived in what is now North Africa during the Late Cretaceous period, around 112 to 93.5 million years ago. The name “Spinosaurus” means “spine lizard”, and refers to the distinctive sail-like structure on its back, which is made up of elongated spines extending from its vertebrae.
Spinosaurus is one of the largest known carnivorous dinosaurs, with some estimates suggesting it could grow up to 18 meters (59 feet) in length and weigh up to 9,000 kilograms (20,000 pounds). Its most notable feature is its long, narrow skull, which is lined with conical teeth that were used to catch and eat fish.
In addition to its sail-like structure, Spinosaurus is also known for its unusual anatomy, which includes a long, crocodile-like snout, relatively short arms, and powerful hind legs. These adaptations suggest that Spinosaurus was a semiaquatic dinosaur that spent much of its time in or around water, using its long snout to catch fish and its powerful hind legs to swim.
Spinosaurus is a very important dinosaur for our understanding of the diversity of life during the Late Cretaceous period in North Africa, and its discovery has helped to shed light on the evolution and behavior of large theropod dinosaurs. However, much about this fascinating dinosaur remains a mystery, and scientists are continuing to study its fossils in order to learn more about its life and behavior.
