Scientists have found a fossil of a strange domestic predator because most dinosaurs do not live underwater.
Scientists have found fossils that show a mysterious hunting dinosaur that lived in northern Africa about 95 million years ago. The dinosaur possessed a long tail that helped it swim in the water, according to the New York Times.
If this is true, the beast is about 12 meters long and not fully mature when it dies, a rare swimming dinosaur.
Nizar Ibrahim, a biology professor at Detroit Mercy University in Michigan, told the New York Times: “It was an underwater hunting dinosaur.”
In an article published on April 29 in the journal Nature, Dr. Ibrahim and his colleagues described the skeleton of Spinosaurus aegyptiacus (meaning “living Egyptian lizard”). It has long, vertical spines from the bone at its tail about 4.5 meters long that form a fin-like structure and, according to the theory of scientists, used to swim.
This animal is a combination of a lizard and an eel in the size of a Tyrannosaurus rex.

“There is no animal equivalent to it in modern times,” said Ibrahim. “It’s like you’re working with a creature from space.”
Dinosaurs ruled the earth for 180 million years. But during that time, they didn’t seem to be underwater. Other reptiles of the same era, such as the plesiosaur’s lizard and the mosasaur, swam in the sea, but they are not dinosaurs.
This newly discovered animal is definitely a dinosaur. It belongs to the group of dinosaurs. This group also includes tyrannizard and velociraptor.
In 2014, Mr. Ibrahim described an intact fossil excavated in Morocco. He argued that the fossil had characteristics suitable for living in water, like crocodile-like jaws, ball-like bones, and flat feet like oars. The Sahara region is the largest desert in the world.
But in the Cretaceous, when Spinosaurus aegyptiacus lived, this place had a large system of rivers and lakes.
From 2015-2019, Mr. Ibrahim has returned to the archaeological site in Morocco many times.
The team removed more than 15 tons of rock on a slope, persevering through sandstorms, snakes, floods and temperatures up to 49 degrees C. They found a bone near the end of the spiked specimen’s tail straight.
Unlike the tails of most carnivorous dinosaurs, the Spinosaurus aegyptiacus tail bones are not interlocking and that shows that its tail can move more, moving up and down like a snake.
