Named By: S. G. Dalman - 2014.
Classification: Chordata, Reptilia, Saurischia, Theropoda, Ceratosauridae.
Species: F. churei (type).
Size: Paratype fibula 27.5 centimetres long. Scaled and reconstructed to Elaphrosaurus proportions results in a rough estimate of up to about 2.5 meters long.
Known locations: USA, Wyoming - Morrison Formation (Brushy Basin Member).
Time period: Kimmeridgian of the Jurassic.
Fossil representation: Tibia, astralgus and fibula from two individuals.
was a ceratosaurid
theropod dinosaur that lived in North America during
the late Cretaceous. At the time of writing the only parts that are
known for Fosterovenator are lower leg bones, but
in the original
description of this genus, the fossils were noted as being
superficially similar to those of the genus Elaphrosaurus,
gracile theropod dinosaur that lived in the late Jurassic of Africa,
though several fossils from the North American Morrison Formation have
been speculated as belonging to Elaphrosaurus or Elaphrosaurus-like
dinosaurs before the description of Fosterovenator.
If indeed built in a similar way to Elaphrosaurus, then Fosterovenator would have been a predator that focused upon speed and agility to hunt smaller, possibly juvenile dinosaurs. However this speed would have also been the best defence for Fosterovenator as the genus lived in the same area and at the same time as much larger and more powerful predatory dinosaurs such as Torvosaurus, Allosaurus and possibly even Ceratosaurus.
