"Ninja giant" from Argentina turned out to be the most ancient representative of the genus of titanosaurs

Dinosaurs were not going to die out before the fall of the asteroid

Dinosaurs were not going to die out before the fall of the asteroid

At least, this is evidenced by a new study by scientists from the UK. They believe that if the asteroid had not hit the Earth about 65 million years ago, then these lizards might have continued to dominate the planet

Megalodon's giant teeth turned out to be a side effect of evolution, not an adaptation to hunting

Megalodon's giant teeth turned out to be a side effect of evolution, not an adaptation to hunting

Scientists from the UK found that Megalodon's teeth were a byproduct of growth rather than an adaptation to eating habits. They coped with their tasks no better than the teeth of the smaller ancestors of these sharks

Scientists first determined the true dimensions of the ancient megalodon

Scientists first determined the true dimensions of the ancient megalodon

The new study helped to establish not only the length of the giant megalodon, but also the dimensions of the rest of its body. In addition, if earlier this extinct species of cartilaginous fish was compared mainly with the great white shark, now the analysis included five modern sharks of the order of lamniform

Paleontologists have learned what could have influenced the extinction of megalodons

Paleontologists have learned what could have influenced the extinction of megalodons

As scientists have found out, giant sharks left their young in shallow water, where it is warm, a lot of food and few predators. As they grew, these fish conquered more and more water, but climate change forced the offspring of megalodons to go through hard times

Considered a hulking antheosaurus, it turns out to be an agile hunter-killer

Due to its gigantic size, the anteosaurus was considered slow and awkward. But a detailed analysis of its bones showed that this animal possessed swiftness and can probably be considered one of the most terrifying predators of its time. Scientists have already called it the "analogue" of the Tyrannosaurus rex, which lived 200 million years later

New dinosaur species discovered with long spikes protruding from its shoulders

New dinosaur species discovered with long spikes protruding from its shoulders

The unusual dinosaur was very different from its counterparts and, although it could be comparable in size to a chicken, it was difficult not to notice it. It's all about the thick "mane" and absurdly long thorns-ribbons of keratin, which grew from the shoulders of the animal. Nothing of the kind has yet been found in the fossil record, according to an international group of researchers studying the remains
