0.74" Afrovenator or Spinostropheus tooth from the Tiouraren Formation of the Agadez region of Niger. This exceptionally rare tooth from a very old collection is rare to find. This tooth is either from Afrovenator (a megalosaurid) or Spinostropheaus (A ceratosaurid). I lean towards Spinostropheus because of the smaller size of the serrations. Only one carinae has serrations present, sadly, the other carinae serrations have been worn off. There is some wear on one side of the tooth. Between 167-161 Million years old.
