Megalosaurid Tooth, Afrovanator abakensis (Niger) #05

Description

A rare Jurassic theropod tooth from the Tiouraren Formation (Niger).  This tooth features some good enamel and serrations, but it is missing the tip and has a couple of neat repairs.

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, however the size, shape and serration counts suggest this one belongs to a Megalosaurid, most likely Afrovanator abakensis. Comes labelled and stored in an acrylic case with padding. 

Tooth measurements are as follows:

Crown Base Ratio: 0.53

Crown Height Ratio: 1.63

Mesial Serration Count (per 5mm): 14

Distal Serration Count (per 5mm): 11

The mesial carina appears to end less than 1/2 way down the crown.

Condition: Good

Size: 1.19 inch

Age: 167 Million Years

Locality: Agadez, Niger (Tiouraren Formation)
