Islamabad ( The COW News Digital)Paleontologists have uncovered the fossilized remains of a fearsome crocodile-like creature in southern Patagonia, dating back approximately 70 million years to the dinosaur era. The species, named Kostensuchus atrox, provides an extraordinary glimpse into the predatory ecosystem of the Late Cretaceous period.
The newly discovered predator measured about 3.5 meters (11.5 feet) in length and weighed roughly 250 kilograms (550 pounds). It possessed a wide and powerful jaw lined with sharp, serrated teeth, ideal for tearing flesh, making it a formidable carnivore of its time. Experts believe its strong, straight forelimbs were adapted for tracking and capturing prey, allowing it to hunt smaller or medium-sized dinosaurs effectively.
The fossil was found in the Corello Formation, a region known for its diverse Late Cretaceous ecosystem. During that period, the area experienced a warm and seasonally humid climate, with water-filled valleys supporting a variety of life forms, including dinosaurs, marine turtles, amphibians, and early mammals.
“Kostensuchus atrox was a top predator in its ecosystem,” said lead paleontologist Dr. Mariana Soto. “Its presence would have played a significant role in maintaining the balance of species, controlling herbivore populations, and shaping the ecological structure of the region.”
The discovery of this crocodile-like predator highlights the rich biodiversity of Patagonia during the Mesozoic era. Fossils of other carnivorous species have previously been found in the region, but Kostensuchus atrox stands out due to its unique adaptations, including its robust jaw and predatory efficiency.
Researchers also noted that the specimen’s physical features suggest it could have ambushed prey in aquatic environments, making rivers and lakes in the Corello Formation ideal hunting grounds. Its ability to tackle a range of prey demonstrates its versatility as a dominant carnivore during the dinosaur era.
This finding not only adds to the understanding of crocodilian evolution but also provides insights into predator-prey dynamics of prehistoric South America. Further studies are planned to explore the relationship between Kostensuchus atrox and other coexisting species, shedding light on the complex food webs of the Late Cretaceous period.
The fossil is now preserved in a local museum in Patagonia, allowing scientists and enthusiasts to study and appreciate the extraordinary predator that once ruled the ancient landscapes of South America.
