Fossils of a large carnivorous dinosaur that was a top predator about 115 million years ago have been unearthed in Thailand — a brute that was among the early members of an impressive group of flesh-ripping dinosaurs known for their shark-like teeth.

Scientists on Wednesday said the dinosaur, named Siamraptor suwati, was more than 26 feet (9 meters) long and weighed at least 3.5 tons. Siamraptor, the largest carnivorous dinosaur ever discovered in Thailand, lived during the Cretaceous Period in an environment centered on a meandering river system and preyed on plant-eating dinosaurs, the researchers said.

Paleontologist Duangsuda Chokchaloemwong of Nakhon Ratchasima Rajabhat University and Khorat Fossil Museum in Thailand said partial skeletons of four Siamraptor individuals were discovered in Korat, Thailand. The fossils include parts of the skull, backbone, limbs, hips and teeth.
