Named By: Paul Sereno etal. - 1996.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Ceratosauria.
Species: D. agilis (type).
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.
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
Swift speed may have also helped Deltadromeus to
out of the way of other much larger meat eating dinosaurs such
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.
