where did spinosaurus live

- December 6, 2020 -

Although dry and barren now, North Africa was … 16.The Spinosaurus lived in large bodies of water which reached across the whole of the North African coast. The partial Spinosaurus skeleton Ibrahim his colleagues analyzed suggests the specimen was 50 feet (15.2 m) long and still growing. One pterosaur bone was found with a Spinosaurus tooth embedded in it, suggesting they also fed on non-aquatic creatures. However, not all dinosaurs lived together at the same time or in the same place. Spinosaurus (meaning "spine lizard") is a genus of theropod dinosaur which lived in what is now North Africa, sometime during the Albian and Cenomanian stages of the Cretaceous period, about 112 to 93.5 million years ago. Because of this, the only evidence we have of interactions is actual physical marks left on the bones of other dinosaurs. The first Spinosaurus partial skeleton was unearthed in 1912 by Richard Markgraf in the Bahariya Formation of western Egypt.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. Stay up to date on the coronavirus outbreak by signing up to our newsletter today. Just about every inhabitable corner of the planet had dinosaurs. This makes humans undeniably interested in them, but what do we actually know about these reptiles? It is the longest theropod found so far. It lived during part of the Cretaceous period, about 112 million to 97 million years ago, roaming the swamps of North Africa. It may have been able to spread the sail when threatened or looking to attract a mate. The find, detailed in the journal Nature, suggests the fish-loving spinosaurs also hunted (or scavenged) nonaquatic animals. However, Ibrahim and his colleagues found that the spines were composed of dense bones with few blood vessels and were likely wrapped snugly in skin, which doesn't support the thermoregulation idea. The Eoraptor, shown above, was one of the earliest dinosaurs. In 1915, German paleontologist Ernst Stromer published an article assigning the specimen to a new genus and species Spinosaurus ae… Spinosaurus is only known from fragmentary remains. 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. In late 2014, researchers made a stunning announcement: Spinosaurus pursued a semiaquatic lifestyle, and may have spent more time submerged in the rivers of its northern African habitat than it did stomping around on dry land. Just like behavior, no one knows just how these creatures reproduced. This would be incredibly difficult to provide in a zoological setting. It is only due to Stromer's meticulous notes, including detailed descriptions and sketches, that much of the scant knowledge surrounding this dinosaur has been retained. The evidence: the positioning of Spinosaurus' nostrils (toward the middle, rather than the end, of its snout); this dinosaur's small pelvis and short hind legs; … "The sail was likely used as a display structure," Ibrahim told Live Science. NY 10036. However, other scientists took issue with the study's methods, and instead claimed the behemoth was 41 to 47 feet (12.6 to 14.3 m) long and 13.2 to 23 tons (12 to 20.9 metric tons), according to a 2007 study in the same journal. Spinosaurus is featured in the game Jurassic World: Alive. The only place archaeologists have found fossils is in northern Africa. These archaeologists also study the environment based on the rock surrounding the fossils. In fact, some scientists estimate that these creatures could reach lengths of nearly 60 ft. or more! There were also a few large, slanted teeth that interlocked at the end of the snout. In addition to anatomical evidence, chemical analyses also suggest Spinosaurus preferred to dine on fish, a 2010 study in the journal Geology shows. Write CSS OR LESS and hit save. What we can agree on is that they were huge! It is known for the tall sail/hump on its back and its croc-like face. They would have also needed immense amounts of food. This genus was first known from Egyptian remains discovered in the 1910s and described by German paleontologist Ernst Stromer. By signing up, you'll get thousands of step-by-step solutions to your homework questions. They were the largest carnivorous dinosaur. This allowed the animal to move easily in water, but made movement on land nearly impossible unless the dinosaur used all four legs. In the 1990s, new discoveries emerged revealing a crocodile-like snout, as well as bones in… Evolutionists claim dinosaurs lived millions of years ago. There has been much scientific debate regarding the evolution and purpose of Spinosaurus' sail. 18 March 2016. [Images: Digging Up a Swimming Dinosaur Called Spinosaurus]. As we’ve seen, the earliest estimate as to when dinosaurs appeared was around 243 million (243,000,000) years ago. In a 1997 study published in the Journal of Paleontology, paleontologist Jack Bowman Bailey proposed that Spinosaurus and the similar Ouranosaurus didn't have sails after all, and instead had large, bisonlike backs. Because of its size, this dinosaur did not have many predators, but the sail could have been used to ward off enemies, as the dinosaur would have appeared to be twice its size with the sail fully extended. Scientists can’t quite agree on their size, some estimated that they measured up to 49 ft. and 6 tons, while others estimated that they grew to 59 ft. and 9 tons. Joseph Castro - Live Science Contributor They might have had a diet similar to modern-day crocodiles. They likely returned to land to lay eggs, and could even have guarded their nests. You will receive a verification email shortly. Spinosaurus was a large carnivorous dinosaur that was native to what is now northern Africa. Live Science is part of Future US Inc, an international media group and leading digital publisher. Hatchlings were likely prey to other, larger, predators. Other paleontologists have hypothesized that Spinosaurus used its sail to regulate its body temperature by absorbing heat or storing fat. "It would have been visible from far away and even when the animal was swimming. The first remains were found in Egypt by a German palaeontological team led by Ernst Stromer in 1915 and brought to a museum in Munich. 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. Spinosaurus is a very big theropod (meat-eating dinosaur) that lived during the Early Cretaceous period in North Africa. Its environment was likely very warm and humid, with many rivers and lakes flowing through, considering Spinosaurus and Sarcosuchus have been found in the same location. The scientists who study fossils are archaeologists. By signing up, you'll get thousands of step-by-step solutions to your homework questions. By 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).
