It was Spinosaurus aegyptiacus, a 50-foot long creature with powerful jaws and a solid, spiny sail on its back that dwelled in Northern Africa 95 million years ago.

Was Megalodon bigger than a blue whale?

Monster-size sharks in The Meg reach lengths of 20 to 25 meters (66 to 82 feet). That’s massive, although a tad smaller than the longest known blue whales. Scientists have made estimates of how big C. megalodon got, based on the size of their fossil teeth. Even the largest reached only 18 meters (about 60 feet).

Was anything bigger than a blue whale?

As the biggest animal ever to have lived, the blue whale (Balaenoptera musculus) seemingly obliterates any other animal’s chances at the length title. Even a new-born blue whale is longer than a giant reticulated python. The largest blue whales are found in the southern hemisphere.

Was argentinosaurus bigger than a blue whale?

The blue whale has the new sauropod beat, however. Though the ocean mammal is shorter by about 30 feet, the largest blue whales are estimated to weigh as much as 320,000 pounds. To be fair, the blue whale never has to support its bulk on land.

The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs’ food supply.

How hard can at Rex bite?

When Bates and Falkingham used computer models to simulate T. rex’s bite, the result was “quite surprising,” Bates told us: a maximum bite force of almost 12,800 pounds, about the equivalent of an adult T. rex’s body weight (or 13 Steinway Model D concert grand pianos) slamming down on its prey.
