Nowadays, the land near Ban Saphan Hin in central Thailand is a place where local farmers plant tapioca and corn, but millions of years ago, this area was terrorized by fearsome Dinosaurs. The excavations performed in Thailand revealed a new genus and species of predatory dinosaurs called Siamraptor suwati. These newfound species belong to the group called carcharodontosaurs. Dinosaurs of this group are known for their serrated, knife-like teeth. Fossils of these huge shark teeth dinosaurs are dated back more than 113 million years. This fossils study was released in an open-access journal PLOS ONE, on October 9th, 2019.
As described in the journal, Siamraptor suwati is most complete dinosaur amongst its type and age, ever found in Southeast Asia. The fossils of a 25-foot beast add up to the list of major dinosaurs from the region. These fossils also reveal insight into how these dinosaurs spread through the ancient world. Steve Brusatte, a paleontologist from Edinburgh University, reviewed the paper, and according to him, this discovery is significant as Siamraptor suwati is one of the most important dinosaurs ever found in the Thai region. And if findings are considered then it is safe to mention that it would have been fast fierce and a dynamic beast.
Ten Million years ago, when giant tyrannosaurs were not in the picture, another group of huge predatory dinosaurs reigned, called the allosauroids. Among these huge carnivores, was a group known as carcharodontosaurs. They were the top predators amongst most of the Cretaceous. It was the decline of carcharodontosaurs, after which small tyrannosaurs got huge, and they moved into the role of an apex predator. For the last couple of decades, Thai paleontologists are discovering a lot of fossil material from the dinosaurs’ period. An international team, Japan-Thailand Dinosaurs project, has discovered two new herbivore dinosaurs. This discovery of Siamraptor suwati reveals that carcharodontosaurs were widespread around the globe by the initial Cretaceous period.
