This tooth is an excellent dinosaur fossil for the price-point and it would surely make for a memorable gift.

It belonged to a _Spinosaurus_, one of the most imposing animals to have ever walked the planet. _Spinosaurus_ was a gigantic carnivorous dinosaur with an impressive sail on its back. It surpassed _T-Rex_, and other contemporary carnivores, in overall size, measuring as much as 59 feet by some estimates.

This Cretaceous predator was also unique in that it was a semi-aquatic quadruped. The way its skeleton is balanced suggests that it walked on all fours and its skull shape shares similarities with crocodilians. Notably, _Spinosaurus_ has an elongated skull with conical teeth lining its jaws and raised nostrils, which enabled it to effectively capture fish in the extensive river system that is now North African desert.

There is no consensus among scientists regarding the purpose of the distinctive 5-6 foot high "sail" (or possibly, hump) that extended from its vertebrae. Proposed functions include thermoregulation, display or a combination thereof.
