Argentina, September 24: Paleontologists in Patagonia have identified a new species of dinosaur, named Joaquinraptor casali, that lived during the late Cretaceous period around 66 to 70 million years ago. The carnivorous predator, measuring about seven meters in length, belonged to the megaraptor group—large theropods known for their formidable claws and role as apex hunters of their ecosystems.
What makes the discovery remarkable is the state of preservation. The fossilized remains include parts of the skull, limbs, vertebrae, and tail, making it one of the most complete megaraptoran skeletons recovered so far. Researchers noted that a bone from a crocodilian relative was lodged in its jaws, suggesting the dinosaur died during or immediately after feeding. Such evidence provides a rare glimpse into the feeding behavior of these ancient predators, offering a direct connection to the ecological dynamics of the period.
The dinosaur was estimated to be about 19 years old at the time of its death. Its sharp claws, powerful build, and strong jaw structure indicate it was well adapted to hunt and dominate the riverine landscapes of Cretaceous Patagonia. The find sheds light on how megaraptors evolved and interacted with other large reptiles before the mass extinction event that wiped out non-avian dinosaurs.
Scientists named the species Joaquinraptor casali in honor of a young family member of one of the researchers. The discovery underscores not only the richness of South America’s fossil record but also the potential for future finds that could further illuminate the lives of dinosaurs in their final evolutionary stages.
