Prehistoric Dinosaur Hub on Instagram: "Spinosaurus, Giganotosaurus, and Tyrannosaurus rex are often called the “Big 3” because they were among the largest carnivorous dinosaurs ever discovered. Spinosaurus was the longest, adapted to water; Giganotosaurus was one of the heaviest land hunters; and T. rex had the most powerful bite force ever measured in a land animal. Together, they represent the peak of predator evolution in the Mesozoic—giants from different times and continents, each ruling t

Prehistoric Dinosaur Hub on Instagram: "Vitosaura colozacani – The New Abelisaurid from Argentina 🦖🇦🇷 A new carnivorous dinosaur has been discovered in northern Argentina! Named Vitosaura colozacani, this predator lived about 80 million years ago during the Late Cretaceous. It measured around 5 meters long, making it a medium-sized hunter compared to its larger abelisaurid relatives like Carnotaurus. The fossils were found in the Los Llanos Formation in La Rioja Province, a region that was on

Prehistoric Dinosaur Hub on Instagram: "For a long time, Megalodon 🦈 was thought of as the undisputed apex predator of the Miocene and Pliocene oceans. At up to 18 meters long, it certainly dominated much of the seas. But recent studies suggest the picture was more complex. Megalodon shared its oceans with Livyatan, a giant predatory whale almost as large, armed with the biggest functional teeth of any animal. Fossil evidence shows both species lived around the same time, likely competing for t

Prehistoric Dinosaur Hub on Instagram: "Sauropods were the largest land animals to ever walk the Earth, with giants like Argentinosaurus stretching over 30 meters long and weighing more than 70 tons. Yet, despite their enormous size, they began life from surprisingly small eggs, no bigger than a football, leaving hatchlings extremely vulnerable in a dangerous world. Their long necks, some reaching up to 15 meters, allowed them to browse from the tallest trees, but research also shows they likely
