(Dinosauria, Theropoda) from the Lower Cretaceous of Tunisia, with 
remarks on the evolutionary history of the Spinosauridae. Bulletin de 
la Société géologique de France, 5, 415-421.

A fragment of left dentary from the early Albien (Ain el Guettar 
Formation, Chenini member) of Jebel Miteur (southern Tunisia) is 
described as Spinosaurus cf. aegyptiacus.

Following the authors, the family Spinosauridae comprises:

- Baryonichinae: Baryonyx (= Cristatusaurus = Suchomimus)
- Spinosaurinae: Spinosaurus, Irritator (= Angaturama)
- Siamosaurus ?

Baryonychines were replaced by the more avanced spinosaurines in the 
Albian and Cenomanian.
