The Sunday Challenge: Odd This lifesize spinosaurus is visiting Quincy Marketl in Boston, Massachusetts in the hopes that it will entice you to pay $25 to see other moving and growling dinosaur replicas inside the marketplace. "Spinosaurus (meaning "spine lizard") is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian to upper Turonian stages of the Late Cretaceous period, about 99 to 93.5 million years ago.[2][3] This genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915. The original remains were destroyed in World War II, but additional material has come to light in the early 21st century.... Spinosaurus is the largest of all known terrestrial carnivores; other large carnivores comparable to Spinosaurus include theropods such as Tyrannosaurus, Giganotosaurus and Carcharodontosaurus. Estimates published in 2005, 2007, and 2008 suggested that it was between 12.6 to 18 meters (41 to 59 ft) in length and 7 to 20.9 metric tons (7.7 to 23.0 short tons) in weight.[4][5][6] New estimates published in 2014 and 2018, based on a more complete specimen, supported the earlier research, finding that Spinosaurus could reach lengths of 15 to 16 meters (49 to 52 ft).[7][8][9] The latest estimates suggest a weight of 6.4 to 7.5 metric tons (7.1 to 8.3 short tons). The skull of Spinosaurus was long, low and narrow, similar to that of a modern crocodilian, and bore straight conical teeth with no serrations. It would have had large, robust forelimbs bearing three-fingered hands, with an enlarged claw on the first digit. The distinctive neural spines of Spinosaurus, which were long extensions of the vertebrae (or backbones), grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors[who?] have suggested that the spines were covered in fat and formed a hump. Spinosaurus's hip bones were reduced, and the legs were very short in proportion to the body. Its long and narrow tail was deepened by tall, thin neural spines and elongated chevrons, forming a flexible fin or paddle-like structure." en.wikipedia.org/wiki/Spinosaurus A20211126 104009
