Spinosaurus is a genus of spinosaurid dinosaur that lived in what now is North Africa during the upper Albian to upper Turonian stages of the Cretaceous period, about 112 to 93.5 million years ago.

Spinosaurus (signifying "spine reptile") is a sort of spinosaurid dinosaur that lived in what currently is North Africa during the upper Albian to upper Turonian phases of the Cretaceous time frame, around 112 to 93.5 million years prior. This variety was known first from Egyptian stays found in 1912 and depicted by German scientist Ernst Stromer in 1915. The first remains were obliterated in World War II, however extra material has become known in the mid 21st century. It is muddled whether a couple of animal categories are spoken to in the fossils announced in the logical writing. The most popular species is S. aegyptiacus from Egypt, albeit a potential second animal varieties, S. maroccanus, has been recouped from Morocco. The contemporary spinosaurid class Sigilmassasaurus has likewise been synonymized by certain creators with S. aegyptiacus, however different analysts propose it to be a particular taxon. Another conceivable junior equivalent word is Oxalaia from the Alcântara Development in Brazil.

 

Spinosaurus was among the biggest of all known flesh eating dinosaurs, about as extensive as or significantly bigger than different theropods, for example, Tyrannosaurus, Giganotosaurus and Carcharodontosaurus. Assessments distributed in 2005, 2007, and 2008 recommended that it was between 12.6–18 meters (41–59 ft) long and 7 to 20.9 tons (7.7 to 23.0 short tons) in weight.[2][3][4] New gauges distributed in 2014 and 2018, in light of an increasingly complete example, bolstered the prior research, finding that Spinosaurus could arrive at lengths of 15–16 m (49–52 ft).[5][6][7] The most recent evaluations propose a load of 6.4–7.5 tons (7.1–8.3 short tons).[6][7] The skull of Spinosaurus was long, low and tight, like that of a cutting edge crocodilian, and bore straight cone shaped teeth without any serrations. It would have had huge, powerful forelimbs bearing three-fingered hands, with a developed paw on the principal digit. The particular neural spines of Spinosaurus, which were long augmentations of the vertebrae (or spines), developed to in any event 1.65 meters (5.4 ft) long and were probably going to have had skin associating them, shaping a sail-like structure, albeit a few creators have proposed that the spines were shrouded in fat and framed a mound. Spinosaurus' hip bones were decreased, and the legs were short with respect to the body. Its long and limited tail was developed by tall, slender neural spines and lengthened chevrons, shaping an adaptable blade or oar like structure. 

 

Spinosaurus is known to have eaten fish, and most researchers accept that it chased both earthly and oceanic prey. Proof proposes that it was exceptionally semiaquatic, and lived both ashore and in water as current crocodilians do. Spinosaurus' leg bones had osteosclerosis (high bone thickness), considering better lightness control, and the oar like tail was likely utilized for submerged drive. Numerous capacities have been advanced for the dorsal sail, including thermoregulation and show; either to scare equals or draw in mates. Spinosaurus lived in a sticky domain of salt marshes and mangrove timberlands nearby numerous different dinosaurs, just as fish, crocodylomorphs, reptiles, turtles, pterosaurs, and plesiosaurs.
