Scientists Have Found a New Species of Dinosaurs with Shark-Like Tooth in Thailand

Scientists have found a new type of a predatory dinosaur who had needle-like teeth similar to a shark. The study, published on Wednesday in the journal PLOS ONE journal, is associated with the Japan-Thailand Dinosaur Project. An international team of scientists has participated in the study. Mainly, it includes researchers from Fukui Prefectural University (FPU), Japan, and Thailand’s Nakhon Ratchasima Rajabhat University (NRRU). The team surmises the newly-found fossil belongs to the predator community. The 8-meters-long giant is a latest, early member of a famous and extensive group of dinosaurs called the Carcharodontosaurids. The groups’ popular member is Carcharodontosaurus, which means lizard who have shark-like teeth. The tooth structure of these dinosaurs, the same as a shark, could have offered a flesh-tearing ability.

The team named it Siamraptor suwati, a top meat-eating wild animal surviving around 115 million years ago. In Thailand, Siamraptor means robber. The newly-found fossils include a skull, hip remains, teeth as well as backbone. Scientists surmise the giant carnivorous dinosaur ever found in Thailand weighed around 3.5 tons. They have identified the remains belong to a formerly-known species carcharodontosaurian by comparing the parts of the fossil with familiar dinosaurs. The team says Siamraptor survived during the Cretaceous Period in a climate based on a winding river system and fed on herbivorous dinosaurs. Soki Hattori, a paleontologist from FPU, said Siamraptor is the giant predator in the habitat; thus, it could be a top predator at the time.

Hattori has also commented on the looks of the dinosaur forbears. He said the teeth of Carcharodontosaurus, even Carcharodontosaurus, show-specific waves of the surface together with the edge of the thin knife-edged shark-tooth. Notably, scientists have found the same feature in Siamraptor’s teeth. Hattori said they have slightly fabricated, a narrow skull with crests or horns above their skulls. He noted the dinosaurs had strong forelimbs with three fingers. All in all, the finding reveals that Carcharodontosaurus existed across the globe by the early Cretaceous period.
