Description: Spinosaurus (meaning 'spine lizard') was a theropod dinosaur genus that lived in what is now Egypt, from the Albian to early Cenomanian stages of the Cretaceous Period, about 95 to 93 million years ago. According to a study by dal Sasso et al. (2006), it is the largest of all carnivorous dinosaurs, even larger than Tyrannosaurus rex and Giganotosaurus. If the estimates are correct, Spinosaurus would be the longest theropod, measuring 15 to 17.4 metres (49.2 to 57.1 feet) long and reached weights up to 9 tons.
The distinctive "spines" of these animals (long extensions of the vertebrae) grew up to 2 m (6.6ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some have suggested they were covered in muscle and formed a hump or ridge.
Spinosaurus provides the name of a family of dinosaurs, the Spinosauridae, of which other members include Angaturama (probably synonymous with Irritator), Baryonyx, Irritator, Suchomimus, and Siamosaurus.
|NAME:||Meaning - Spinosaurus means "spiny lizard" because it had large bony spines on its back
Named By - Ernst Stromer von Reichenbach
When Named - 1915
|DIET:||Carnivore (meat-eater). Spinosaurus probably ate plant-eating dinosaurs and large fish.|
|SIZE:||Length - 40-50 feet (12-15 m) long
Weight - 4 tons or more
|WHEN IT LIVED:||Middle Cretaceous period, about 97.5-95 million years ago|
|WHERE IT LIVED:||Fossils have been found in Egypt and Morocco, Africa.|
|FOSSILS:||Incomplete fossils have been found, including blade-like neural spines up to 6 feet (1.8 m) long. The original fragmentary fossil specimen from Egypt (found in 1912) was destroyed in World War 2.|
|Spinosaurus' sail may have been for heat dissipation - it lived in a swampy environment near the equator during the warm Cretaceous period. The sail may have also been used to attract mates or seem bigger than it was.|
Each puzzle is supplied with an "Objective Sheet" that explains what it is that you are supposed to do. This sheet also includes a picture/drawing of the puzzle in the unsolved condition, (similar to the one at the top of this page), so there is a reference to look at when putting it back together.
Puzzle solutions are also included with the shipment but are not sealed in the puzzle wrapper. This is done so that the purchaser can make the decision as to when to give the solution to the person that is receiving the puzzle, (as a gift, for example).
