Megalosaurid Tooth, Afrovanator abakensis (Niger) #04

Description

A rare Jurassic theropod tooth from the Tiouraren Formation (Niger).  This tooth features wear to the tip and a couple of 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: 0.47

Crown Height Ratio: 1.53

Mesial Serration Count (per 5mm): N/A

Distal Serration Count (per 5mm): 15

Mesial carina not present as tip is missing, so it likely only extended around half way down the crown.

Condition: Fair/Good

Size: 1 inch

Age: 167 Million Years

Locality: Agadez, Niger (Tiouraren Formation)
