Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Carcharodontosauria.
Species: S. suwati (type).
Size: Uncertain due to lack of remains, but holotype individual roughly estimated to be around 7 meters long.
Known locations: Thailand - Khok Kruat Formation.
Time period: Aptian of the Cretaceous.
Fossil representation: Partial skull bones including jugal, maxilla, premaxaila, approximate rear half of mandible (lower jaw), at least three scattered vertebrae for neck, dorsal and tail, partial ischiums and lower leg bone.
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.
