Theropod Tooth - Megalosaurid/Ceratosaur (Niger) #12

Description

A rare Jurassic theropod tooth from the Tiouraren Formation (Niger).  This is a tooth tip and features some wear.

It's very difficult to ID teeth from the Jurassic of Niger as there's only a small amount of published material to compare against.  This tooth likely comes from the Megalosaurid Afrovanator abakensis, but it could also belong to a Ceratosaurid.

Comes labelled and stored in an acrylic case with padding. 

Tooth measurements are as follows:

Crown Base Ratio: 0.53

Crown Height Ratio: 1.53

Mesial Serration Count (per 5mm): N/A

Distal Serration Count (per 5mm): N/A

As it's only a tooth tip, it's not possible to say how far down the mesial carina extends.

Size: 0.91 inch

Age: 167 Million Years

Locality: Agadez, Niger (Tiouraren Formation)
