Thanatotheristes by cisiopurple ddp2itc-fullview
Thanatotheristes ("death reaper") or Thanatos was a tyrannosaurid theropod dinosaur whose newly described remains were found in Canada. It was closely related to Tyrannosaurus and Daspletosaurus. The full name of the theropod is; Thanatotheristes degrootorum (Greek for “Reaper of Death”). This species thought to be the oldest member of the Tyrannosauridae family yet discovered in northern North America, and would have grown to around eight meters (26 feet) in length. Its species was alive in the late Cretaceous period.



The holotype specimen of Thanatotheristes degrootorum (TMP 2010.5.7) is based on a right maxilla, right jugal, right postorbital, right surangular, right quadrate, right laterosphenoid, left frontal, and both approximated.
