Megalosaurid Tooth, Afrovanator abakensis (Niger) #09

Description

A rare, large Jurassic theropod tooth from the Tiouraren Formation (Niger).  This tooth features some restoration with putty around the middle, but is a big tooth from a rare locality.

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: 0.57

Crown Height Ratio: 2.38

Mesial Serration Count (per 5mm): N/A

Distal Serration Count (per 5mm): 11.5

Mesial carina is very worn, but it seems to extend only around half way down the crown.

Condition: Good

Size: 2 inches

Age: 167 Million Years

Locality: Agadez, Niger (Tiouraren Formation)
