In Thailand, new species of predator dinosaurs with "shark-like" teeth were discovered
Researchers from the Nakhon Ratchasima Rajabhat University (NRRU) in Thailand and the Fukui Prefectural University (FPU) in Japan believe that the dinosaur they called Siamraptor suwati was a top predator about 115 million years ago. It should have been at least 8 meters long.
Her study, part of the Japan-Thailand Dinosaur Project, was published in the open-access journal PLOS ONE.
Soki Hattori, a paleontologist at FPU, was quoted by Reuters as saying, "Siamraptor is the largest predator in the environment and could be a top predator by that time." At least four individual dinosaurs contain parts of the skull, spine, limbs, hips and teeth of this species, according to a press release from the study.
They have provided evidence of the development of the dinosaur group Carcharodontosaur, of which the Siamraptor represents a very early evolutionary fission, the researchers said.
The most famous member of the group is the Carcharodontosaurus, whose name "shark" means "lizard", was selected for its meat-breaking effect. It lived in North Africa 94-98 million years ago and was about 1
5 meters long, according to the British National History Museum.

"This feature is also observed in Siamraptor's teeth," added the paleontologist, according to Reuters.
Hattori told CNN the investigator believed the Siamraptor had been covered with dandruff.
Since the earliest known fossils of this dinosaur group are from Africa and Europe, it was a surprise to find an early member in Southeast Asia.  006] Commenting on CNN, Hattori welcomed the "important" discovery that "sheds new light on this group's early evolutionary history."
