The horror of October. Afrovenator

  Afrovenator 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 has had a muddled taxonomic history with it being described as a relative of Spinosaurus,‭ ‬Eustreptospondylus,‭ ‬Dubreuillosaurus,‭ ‬Megalosaurus 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.
