Patagotitan mayorum reconstruction. A new study published on August 8, 2017 in the journal Proceedings of the Royal Society B. proclaimed a newly named species the heavyweight champion of all dinosaurs: Patagotitan mayorum. It was named after Patagonia region where it was found, and the Greek word “titan”. Six fossils of the species were studied. The dinosaur averaged 122 feet (37 meters) long and was nearly 20 feet (6 meters) high at the shoulder. Based on ash found around them, the fossils were dated to about 100 million years ago.
Previously, another titanosaur called Argentinosaurus was previously thought to be the largest.
According to Kristi Curry Rodgers, a paleontologist at Macalester College who wasn’t part of the study, Patagotitan’s bones show signs that they haven’t completed their growth “means that there are even bigger dinosaurs out there to discover”.
