Mosasaur Tooth

$20.00
You can think of mosasaurs as basically reptilian whales. Thirty-eight genera have been described, they were all-powerful, air-breathing swimmers and, for the most part, they were active predators. Like today's snakes, which (along with monitor lizards) are their closest living relative, mosasaurs had two rows of teeth and those teeth, it turns out, fossilize quite well. Which means that we were able to get some teeth of animals that have been dead for at least 66 million years, which is when the last mosasaurs died out. 
These teeth are embedded in their sedimentary rock matrix and were recovered in Morocco. They are around 5x6cm in size.
