Named By: Z. Dong - 1973.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Carcharodontosauridae.
Species: K. petrolicus (type).
Known locations: China, Xinjiang - Lianmugin Formation.
Time period: Late Aptian of the Cretaceous.
Fossil representation: Partial left maxilla and partial left mandible (lower jaw).
is a genus of carcharodontosaurid
dinosaur that lived in China during
the early Cretaceous. Kelmayisaurus is currently
only known by
partial upper and lower jaws, and because of this the exact size of
Kelmayisaurus is still unknown. There are still
reports of a second
species named K. “grandis” approaching sizes of up to twenty-two
meters long, something that if true would make Kelmayisaurus
largest theropod dinosaur ever. The reality of the matter however is
that this claim appeared in a children’s book and that K.
“grandis” was based upon a single vertebra that modern
palaeontologists are certain belongs to a sauropod dinosaur, and not
a theropod. This means that K. “grandis” does not exist, and
there is no evidence at all that Kelmayisaurus grew
meters in length.
The only valid species of Kelmayisaurus is the type species K. petrolicus, and as mentioned above the size of this species is indeterminate at the time of writing. The holotype fossils of Kelmayisaurus however have been noted as being similar to the genus Eocarcharia.
