Researchers at Nakhon Ratchasima Rajabhat University (NRRU), Thailand and Fukui Prefectural University (FPU), Japan, believe that the dinosaur they named Siamraptor suwati was a top predator about 115 million years ago. It is estimated to be at least 8 meters long.
Soki Hattori, a paleontologist at FPU, was quoted by Reuters: "Siamaptor is the largest predator in the environment and thus can be a top predator at this time."
They have provided evidence for the development of a group of dinosaurs called carcharodontosaurus, of which Siamraptor represents a very early evolutionary rift, the researchers explained.
The most famous member of the group is the Carcharotontosaurus, whose name means "shark" "lizard", was selected because of its effectiveness in tearing flesh. It lived in North Africa about 94-98 million years ago and was approximately 1
