Eocarcharia (from the Greek : Eos = twilight, karcharias = shark, dinops = fearful eyes) is a genus of theropod dinosaurs from the group of Carcharodontosauridae . The animals lived in the Lower Cretaceous ( Aptium to Albium ).
Only the type species E. dinops has been scientifically described (Sereno & Brusatte, 2008).
Fragmented parts of the skull were discovered in 2000 in the Elrhaz Formation in the Ténéré desert in Niger , West Africa . The discovery was published jointly in 2008 by paleontologists Paul C. Sereno and Stephen L. Brusatte .
Eocarcharia is the oldest known Carcharodontosauridae next to Acrocanthosaurus . Its length is estimated to be about six to eight meters.
