A rare Jurassic theropod tooth from the Tiouraren Formation (Niger). Features some a few repairs and worn enamel.
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 one may belong to a Megalosaurid, possibly Afrovanator abakensis, however as it's quite worn a definitive ID isn't possible. Comes labelled and stored in an acrylic case with padding.
Tooth measurements are as follows:
Crown Base Ratio: 0.44
Crown Height Ratio: 1.5
Mesial Serration Count (per 5mm): N/A
Distal Serration Count (per 5mm): 15
Too worn to assess how far down the crown the mesial carina extends.
