What dinosaur has a big sail on his back?

Dimetrodon was a carnivore that grew to a length of more than 3.5 metres (11.5 feet) and had a large “sail” on its back that may have functioned in temperature regulation. The sail was presumably formed by elongated vertebral spines connected by a membrane containing many blood vessels.

What is the Spinosaurus spine for?

Spinosaurus aegyptiacus was probably the largest predatory dinosaur of the Cretaceous period. The function of Spinosaurus’ huge dorsal ‘sail’ remains unsolved, however. Three hypotheses have been proposed: (1) thermoregulation; (2) humpback storage; or (3) display.

Is the Dimetrodon a dinosaur?

Not only was Dimetrodon not a dinosaur, it was not even a reptile! Even though Dimetrodon is often associated with dinosaurs, it evolved long before the first dinosaurs did.

Was Giganotosaurus bigger than Trex?

Today, Giganotosaurus is believed to have been slightly larger than T. rex, though even Giganotosaurus ranks behind Spinosaurus in size among the meat-eating dinosaurs.

What dinosaur is bigger than the T Rex?

Spinosaurus

What dinosaur has a fin on its back?

One of the most immediately recognizable features of Spinosaurus is the large “fin” (also sometimes called a “sail”) on its back. Spinosaurus probably used this fin to help control its body temperature.

What kind of dinosaur has spikes on its back?

Stegosaurus is famous for the rows of big, diamond-shaped bony plates that ran along its back. It was one of the largest members of a group of dinosaurs called stegosaurs, which lived during the Late Jurassic Period. In addition to back plates, these massive plant-eaters had long spikes at the end of their tail.

What did a Spinosaurus have on its back?

Spinosaurus means “spine lizard,” an appropriate descriptor, as the dinosaur had very long spines growing on its back to form what is referred to as a “sail.” The distinctive spines, which grew out of the animal’s back vertebrae, were up to 7 feet (2.1 meters) long and were likely connected to one another by skin.

What is the name of the dinosaur with the spikes on its back?

The dinosaur, now known as the herbivore Bajadasaurus pronuspinax, had two-feet-long spikes protruding from its back. They were likely similar to horns seen on modern-day antelopes with thick keratin covering the bone spikes. The Bajadasaurus pronuspinax roamed Patagonia 14o million years ago in the Cretaceous.
