According to foreign media reports, paleontologists have discovered a new giant predatory dinosaur with very small arms. Meracosaurus, found in northern Patagonia, Argentina, appeared on Earth millions of years before Tyrannosaurus rex. But Juan Canal, a project leader at the Neuquénen Ernesto Bachman Museum in Argentina, said Meracus and Tyrannosaurus rex were not directly related.
After discovering an almost complete forelimb, paleontologists determined that Melax's arm was much smaller than the size of the rest of the body. Similar to those predatory dinosaurs we learn about in movies.
Despite the discovery of many fossils, scientists have not known the specific anatomy of Meracus for nearly 30 years. The fossils recently unearthed by researchers reveal more about this carnivorous dinosaur: It was 36 feet long and weighed more than 4 tons.
