Named By: Paul Sereno, Jeffrey Wilson, Hans Larsson, Didier Dutheil, and Hans-Dieter Sues - 1994.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Tetanurae, Megalosauridae (sometimes reffered to as Torvosauridae).
Species: A. abakensis.
Size: 7-8 meters long.
Known locations: Africa, Niger, Abaka, Tiouraren Formation.
Time period: Generally considered to be of the Hauterivian to Barremian ages of the early Cretaceous. However further study of the sediments at the Tiouraren formation suggest that they actually represent the Bathonian to Oxfordian stages of the mid Jurassic.
Fossil representation: A single, almost complete skeleton. Lower jaw, parts of the skull, some vertebrae, some ribs and parts of pelvis missing. Fore and hind limbs are mostly complete.
is one of the most complete theropod dinosaurs so far discovered in
Africa, the harsh environmental conditions of which can quickly erode
fossils exposed to the elements. Since this time Afrovenator
a muddled taxonomic history with it being described as a relative of
and even Allosaurus.
Today Afrovenator is placed within the
Megalosauroidea, although the exact placement has varied depending
upon the study and author.
There was not a huge variation between different genera’s of large theropods during the late Jurassic, but Afrovenator is noted for having a particularly long humerus which would have given the arms of Afrovenator more reach. Reconstruction shows that Afrovenator was also a lightweight hunter built more for speed.
Another dinosaur from the same formation as Afrovenator is the sauropod Jobaria and while direct evidence is lacking, it’s not impossible that Afrovenator may have hunted these sauropods, particularly smaller juveniles that would have been easier for a predator Afrovenator’s size to handle.
