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.

It could grow over 6 meters long and weigh around 500 kilograms, far bigger than its famous cousin Velociraptor. Like other dromaeosaurs, it had a large sickle-shaped claw on each foot, used for slashing or pinning down prey. With strong legs, sharp teeth, and likely feathers

Extinct Era on Instagram: "Spinosaurus was one of the largest predators of the mid-Cretaceous, a semi-aquatic hunter that fed on fish and shoreline prey in what is now North Africa.

Even at this stage, they carried the proportions of a predator, with relatively large heads, developing jaws, and tiny serrated teeth. Bone studies show that T. rex went through a rapid adolescent growth spurt, gaining several hundred kilograms each year during its teenage years. This growth pushed them from small, fragile hatc
