Siamraptor
is
a genus of carcharodontosaurid
dinosaur that lived in Asia during the
early Cretaceous. The holotype individual of Siamraptor
is only known
from a partial skull, jawbone and a few post cranial bones, so
precise details or any unusual features if they existed, are still
unknown. These scattered bones however do indicate that the holotype
individual of Siamraptor was at least what would be
considered a medium
sized carcharodontosaurid dinosaur.
As
a carcharodontosaurid
dinosaur, Siamraptor would have been a large
predator, probably
with teeth adapted more for slicing flesh as opposed to crunching
through bone. Siamraptor might have hunted plant
eating iguanodontid
dinosaurs since numerous remains of these kinds of dinosaurs are known
from Khok Kruat Formation. These include the genera Sirindhorna,
Ratchasimasaurus
and the similarly named Siamodon.
