Although dry and barren now, North Africa was … This genus was first known from Egyptian remains discovered in the 1910s and described by German paleontologist Ernst Stromer. It lived during part of the Cretaceous period, about 112 million to 97 million years ago, roaming the swamps of North Africa. By They were massive predators with sharp teeth, and would have been ridiculously dangerous. Spinosaurus fossils are searched for in Egypt and Morocco. Visit our corporate site. Two species of Spinosaurus have been named: Spinosaurus aegyptiacus (meaning "Egyptian spine lizard") and Spinosaurus Maroccanus(meaning "Moroccan Spine Lizard") The first described remains of Spinosauruswere found and described in the early 20th century. In a 2005 study in the Journal of Vertebrate Paleontology, researchers estimated Spinosaurus was 52 to 59 feet (16 to 18 m) long and weighed 7.7 to 9.9 tons (7 to 9 metric tons), based on extrapolations from skull measurements. These archaeologists also study the environment based on the rock surrounding the fossils. How Long Ago Did Dinosaurs Live: The Triassic Period. Spinosaurus will appear in the game Jurassic World: Evolution. Spinosaurus is featured in the game Jurassic World: Alive. While its jaw was powerful, none of the teeth were serrated, making it unlikely that it could have used them to tear into tough prey. They were massive creatures, and needed at least a shallow-water setting to survive comfortably. Recent fossil evidence shows Spinosaurus was the first dinosaur that was able to swim, and likely spent most of its life in the water, according to a study published September 2014 in the journal Science. 15.The Spinosaurus lived in North Africa, around the land that is now part of modern-day countries such as Egypt, Morocco and Niger. These creatures were one of the largest carnivores to walk the earth, and were at least as large, if not larger, than Tyrannosaurus. All photos used are royalty-free, and credits are included in the Alt tag of each image. The dinosaur's upper spine was fairly flexible, and its vertebrae had ball-and-socket joints, meaning it was likely able to arch its back to a point. Two Spinosaurus species have been named based on the regions where they were discovered: Spinosaurus aegyptiacus Egyptian spine lizard) and Spinosaurus maroccanus (Moroccan spine lizard). In 1915, German paleontologist Ernst Stromer published an article assigning the specimen to a new genus and species Spinosaurus ae… New York, These included lakes and … What we can agree on is that they were huge! Carcharodontosaurus lived in what is now southern Africa from 105 to 94 million years ago. The partial Spinosaurus skeleton Ibrahim his colleagues analyzed suggests the specimen was 50 feet (15.2 m) long and still growing. Future US, Inc. 11 West 42nd Street, 15th Floor, These humps, Bailey argued, would have acted as dissipative "heat shields" that, unlike sails, would have helped the dinosaurs survive in the hot and dry environment they were thought to have lived in (it's now known that their environment was actually a lush swamp). However, this does not mean they did not roam outside this range, just that their remains did not fossilize. In 2004, researchers found a tooth belonging to Irritator challengeri — a spinosaur, or dinosaur in Spinosaurus' taxonomic family, Spinosauridae — embedded in the remains of a Cretaceous pterosaur (flying reptile). These original remains, which were described and named by Ernst Stromer in 1915, were destroyed in Allied bombing raids on Munich, Germany, during World War II. Spinosaurus means "spine lizard," an appropriate descriptor, as the dinosaur had very long spines growing on its back to form what is referred to as a "sail." Spinosaurus is thought to have survived primarily on fish, including giant coelacanths, sawfish, large lungfish and sharks, which lived in the dinosaur's river system, according to Ibrahim. "The sail was likely used as a display structure," Ibrahim told Live Science. We know very little about Spinosaurus behavior, and additional fossil finds may potentially tell us more. But it is important to realize that when they dig up a dinosaur bone it does not have a label attached showing its date. Other paleontologists have hypothesized that Spinosaurus used its sail to regulate its body temperature by absorbing heat or storing fat. Spinosaurus lived during the late Cretaceous Period. Spinosaurus, or “spined reptile,” was named for its The most notable characteristic of these carnivores was the large, spiny, sail-like projection on their backs. Spinosaurus was larger than both T. rex and Giganotosaurus, which was previously the largest carnivorous dinosaur known. In fact, the entwined fossils of a Protoceratops locked in combat with a Velociraptor were preserved by a sudden, violent sandstorm one unlucky day during the late Cretaceous period. The most famous desert of the Mesozoic Era, the Gobi of central Asia, was inhabited by three very familiar dinosaurs— Protoceratops, Oviraptor, ​and Velociraptor.
