SPINOSAURUS, meaning “Spine Lizard”
PERIOD: Late Cretaceous Period about 98-95 Million Years Ago
DIET:Carnivore - Meat Eater
SIZE:Estimates published in 2005 and 2007 suggest that it was 12.6 to 18 metres (41 to 59 ft) in length and 7 to 20.9 tonnes (7.7 to 23.0 short tons) in weight.

  • Spinosaurus is called "spiny lizard" because it had a series of large neural spines up to 6 feet (1.8 m) long coming out of its back vertebra.
  • It had a large head with sharp, straight, non-serrated teeth in powerful, crocodile-like jaws. Its arms were smaller than its legs.
  • The presence of this sail as a thermo-regulatory device is evidence that Spinosaurus may have been a cold-blooded animal.
  • Spinosaurus was named in 1915 by paleontologist Ernst Stromer von Reichenbach, from an African fossil. Fossils have been found in Egypt and Morocco, in Africa. Very few Spinosaurus fossils have been found, and they are incomplete.
