Can dinosaurs come back?
The answer is YES. In fact they will return to the face of the earth in 2050. We found a pregnant T. rex fossil and had DNA in it this is rare and this helps scientists take a step closer of animal cloning a Tyrannosaurus rex and other dinosaurs.
Did Tyrannosaurus Rex eat fish?
It was one of the largest carnivores to stalk the land. An almost complete skeleton of the fish-eating dinosaur has been found in fossil beds of the Tenere Desert in central Niger. The fossil shows the living animal must have rivalled the largest carnivore, Tyrannosaurus rex, in size and ferocity.
What was the first fish ever?
The first fish were primitive jawless forms (agnathans) which appeared in the Early Cambrian, but remained generally rare until the Silurian and Devonian when they underwent a rapid evolution.

Are dinosaurs still alive in 2021?
In an evolutionary sense, birds are a living group of dinosaurs because they descended from the common ancestor of all dinosaurs. Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.

Would a T. rex eat a human?
T. rex surely would have been able to eat people. There are fossil bite marks, matching the teeth of T. rex, on the bones of Triceratops and duck-billed dinosaurs such as Edmontosaurus, which were both over 50 times heavier than an average person.

What animal did fish evolve from?
Later, about 420 million years ago, the jawed fish evolved from one of the ostracoderms. After the appearance of jawed fish, most ostracoderm species underwent a decline, and the last ostracoderms became extinct at the end of the Devonian period.
