Named By: S. L. Brusatte & R. B. J. Benson - 2013.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Tyrannosauroidea.
Species: J. langhami (type).
Size: For holotype individual, femur (upper leg bone) about 55 centimetres long, tibia (lower leg bone) about 68 centimetres long. Total body length roughly estimated to be about 5 meters long.
Known locations: England, Dorset - Kimmeridge Clay Formation.
Time period: Tithonian of the Jurassic.
Fossil representation: Partial post cranial remains, including, pelvis, rear limbs and vertebrae.
discovered in 1984 and originally described as a species of
in 2008, S. langhami was re-described as a
genus of tyrannosaur
in 2013. As is standard practice with such
occurences, the original species name of langhami was retained to
create the new type species, Juratyrant langhami.
The species name
is in honour of Peter Langham who first discovered the remains.
Juratyrant was typical of the early tyrannosaurs in that it was far smaller than later genera that lived at the end of the Cretaceous such as Albertosaurus and Tyrannosaurus. Juratyrant would have lived along other kinds of dinosaurs such as stegosaurs like Dacentrurus, though its small size means that it may have focused its hunting upon smaller dinosaurs or the recently hatched juveniles of larger dinosaur genera. The main defence Juratyrant would have had against larger theropod dinosaurs of the time would have been its speed.
Juratyrant is not the first tyrannosaur known to have lived in England, Eotyrannus was described in 2001.
