The age of dinosaurs 70 million years ago was an era of giant beasts, and today's terrestrial animals would have to be considered small if they were put into that period.
For example, the largest animal on land, the elephant, can only grow to 5-6 tons. But 70 million years ago, sauropods were tens of tons, almost ten times larger than elephants.
The picture above shows the largest species in the dinosaur era, sauropod dinosaurs
Even the giant carnivorous dinosaurs were much larger than elephants. For example, the dinosaur introduced today is a giant. The carnivorous dinosaur Tyrannosaurus rex, which is famous for its gigantic size, is only a small man in front of it. This dinosaur is the famous spinosaurus, a carnivorous dinosaur that lived in northern Africa.
Its body length can grow to 14 meters, height can grow to 5 meters, and weight may reach up to 8 tons, while the Tyrannosaurus rex weighs only 6 tons, which is 1.3 times the difference, which shows the size of this dinosaur. The biggest feature of spinosaurus is the high and bulging back, which is said to allow spinosaurus to dissipate heat efficiently in hot equatorial regions, and the confusion of the back will make it look very tall and can also scare potential opponents.
Spinosaurus lived between 114 million and 65 million years ago, when northern Africa was still a hot and humid swamp, where spinosaurus lived.
They were not as fierce as T. rex, and Spinosaurus were relatively mild animals, as can be seen from their diet. Most of the time, they feed on fish, only occasionally preying on small and medium-sized dinosaurs. Therefore, their bite force is lower than that of T. rex, because these small animals do not need much effort to eat it, according to the principle of use and retreat, their mouth muscles are difficult to grow as strong as T. rex.
Due to dietary reasons, the mouth of Spinosaurus is different from that of ordinary dinosaurs, but it is very similar to that of crocodiles. And their forelimbs are very developed, so they can move forward on both two and four legs. It is estimated that when they swim in the water, such limbs can help them to stir the water like a dog planer, allowing them to move forward quickly. Therefore, Spinosaurus is an amphibian animal, so that their food range is much larger than most dinosaurs, which may be the reason why they were able to live on Earth for nearly 50 million years!
