This is a Mosasaur tooth
The Mosasaur was an early crocodile type marine reptile from the late Cretaceous.
You will receive one of the pictured teeth.
They all have lovely shiny enamel enamel with super colouration.
A few of the teeth have slight damage, but this is common with these fragile teeth.
The tooth will come in a padded gem jar and is a super little fossil.
