Deltadromeus

Name: Deltadromeus ‭(‬Delta runner‭)‬.
Phonetic: Del-tah-dor-me-us.
Named By: Paul Sereno etal.‭ ‬-‭ ‬1996.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Ceratosauria.
Species: D.‭ ‬agilis‭ (‬type‭)‬.
Diet: Carnivore.
Size: Estimated‭ ‬8‭ ‬meters long.
Known locations: Morocco‭ ‬-‭ ‬Bahariya Formation and Kem Kem Beds.
Time period: Cenomanian of the Cretaceous.
Fossil representation: Two individuals but of partial remains.‭ ‬Skull is unknown.

       Deltadromeus was a mid-sized theropod that lived in North Africa,‭ ‬but while the time period it is known from places it in the late‭ (‬or alternatively upper‭) ‬Cretaceous,‭ ‬it actually roughly lived during the middle of this period.‭ ‬The skull of this dinosaur is so far unknown but the recovered post cranial remains suggest a fairly agile and fast predator that may have preyed upon ornithopod dinosaurs similar to Ouranosaurus.‭ ‬Swift speed may have also helped Deltadromeus to stay out of the way of other much larger meat eating dinosaurs such Carcharodontosaurus and Spinosaurus,‭ ‬both of which seem to have been present in North Africa during the early Cenomanian.
       Deltadromeus has an uncertain future as a valid genus as another theropod named Bahariasaurus which was named in‭ ‬1934‭ ‬has been suggested as being the same dinosaur as Deltadromeus.‭ ‬The problem here is that the type specimen of Bahariasaurus was destroyed in World War Two,‭ ‬and without further remains it is currently impossible to compare known Bahariasaurus remains with Deltadromeus fossils.‭ ‬Without the possibility of establishing‭ ‬a link Deltadromeus remains a valid genus,‭ ‬but should it ever be proven that these genera are the same‭; ‬Deltadromeus would become a synonym to Bahariasaurus,‭ ‬with all known remains being reassigned to the latter genus.
