Cretaceous Dinosaur Era, 100 million years ago.

Onchopristis, a massive sawfish from the Upper Cretaceous seas, is notable for its distinctive 2.5-meter-long rostrum lined with sharp barbs—hence the name "Giant Saw." This ancient predator primarily fed on crustaceans and used its saw-like snout to dig in shallow waters. Fossil evidence shows that these ocean ecosystems were inhabited by individuals who migrated into freshwater rivers to breed, seeking safer environments for their young. During these migrations, they faced predators like Spinosaurus, which frequently hunted them. The survival of Onchopristis relied on its large populations, making each fossil a remarkable piece of prehistoric history worth collecting.
