What is dino with spine?

Dinosaurs with spines are also known as sauropods. They are characterized by their long necks, tails, and massive bodies. Sauropods were one of the largest animals to have ever walked the Earth, with some species reaching lengths of up to 100 feet and weighing over 100 tons.

They are most known for their unique spinal structure which helped support their large bodies. The vertebrae of sauropods were hollow and filled with air, making them lighter while still being strong enough to support the animal's massive weight. In fact, the largest known land animal to have ever existed was a sauropod called Argentinosaurus, which weighed around 100 tons!

Sauropods lived during the Mesozoic era, from around 230 to 65 million years ago, and were plant-eaters. Despite their size, sauropods were successful in a variety of environments, from the forests of North America to the deserts of Africa. Their extinction, along with other dinosaurs, is still a mystery to scientists and continues to fascinate and intrigue people all over the world.
