However, this theory by Hone and Holtz was later outdated by a more recent research. suggested that the degree of aquatic attributions suggested earlier are not consistent although Spinosaurus presumably had more terrestrial generalist, wading lifestyle similar to modern avians such as herons, skuas, petrels, and storks. At the same time, due to the structure of the upper and lower jaws and the shape of the teeth of Spinosaurus, the bite force of Spinosaurus is relatively small among carnivorous dinosaurs. In addition, according to the study of Spinosaurus, the way of walking may often be carried out with four limbs. If true, this suggests Spinosaurus was present in Africa and South America during the Cretaceous period. There is also some evidence that Oxalaia, a spinosaur from Brazil, is the same animal as Spinosaurus. Studies of the sub-adult specimen Sereno and Ibrahim recovered from their 20 expeditions to Morocco further suggested Spinosaurus preferred to hunt in shallow water. These new discoveries suggested that Spinosaurus was better adapted to life in water than previously assumed, rendering its physical appearance in the Jurassic Park franchise outdated. In 20, the nature of Spinosaurus was rendered even stranger when it was discovered by paleontologists Nizar Ibrahim and Paul Sereno to have possessed short hind legs, webbed feet, and a long, paddle-like tail similar to a newt or crocodile's and that the sail was probably more rectangular. New fossils of both dinosaurs would not be uncovered again until roughly 68 years later, though drawings and photos of the Spinosaurus specimens recovered by Stromer remained intact. The museum was an unfortunate casualty of the raid, as it was right across the street from the Nazi Party's headquarters (the intended target), and the museum's curator had refused to move the fossils to a safer location. Unfortunately, on April 24/25 in 1944, the fossils, along with the original specimen of Carcharodontosaurus and most of Stromer's other collection of fossils, were destroyed during a British bombing raid in World War II, when Allied Forces attacked Berlin, Germany. Similar to its relatives within the spinosauridae, it had large, powerful arms and enormous, hook like claws for grabbing prey, much like modern bears do today.ĭiscovered by German paleontologist Ernst Stromer in 1912, the first Spinosaurus fossils were kept in the building that housed the Bavarian State Collection of Paleontology. The sail might have been used to attract a mate, making it look bigger to other predators it shares with, or speculatively act as a dorsal fin as it moves through the water. The spines of Spinosaurus were tremendous, the longest one found measured over 1.7 meters (5 feet) tall. This sail was comprised of spines that extended from the top of the backbones of all dinosaurs and vertebrates. Its most distinctive feature was the huge sail on its back. to a 2022 estimate of 46 feet (14 meters) and 8.2 tons (16,400 pounds) by Paul Sereno et al. Estimates of the animal's size have ranged from 59 feet (18 meters) and 9.9 tons (19,800 pounds) in 2005 by Del Sasso et al. Its smaller relatives include Suchomimus, Baryonyx, Irritator, Ichthyovenator, and a newly discovered species called Iberospinus. It is also the largest species of spinosaurid, with the largest specimen, MSMN V4047 reaching 14 meters (46 feet) in length, although classification of MSMN V4047 remains highly debated in the scientific community. Spinosaurus is argued to be the longest of all known carnivorous dinosaurs, even longer than Carcharodontosaurus, Giganotosaurus, and Tyrannosaurus rex. Spinosaurus (meaning "spined lizard") is an extinct genus of spinosaurid theropod dinosaur that existed in what is now North Africa during the Cretaceous period.
