Stegosaurus was a large plant-eating dinosaur that lived during the Upper Jurassic (155-150 million years ago) in what it now western North America. It had an unusually small head and very short front legs. Stegosaurus was armed with a spiked tail and had two rows of large bony plates on its back.
Characteristics: Very young Stegosaurus were quite similar to the adults except that their heads are relatively larger, and their tail spikes and back plates were smaller. It is possible that the babies were protected from predators by the adults, and so didn’t need their tail spikes to ward off attack.
Historically, Arabian Foals were the result of intense, selective breeding by their Bedouin masters, who were quite particular about which horses should be allowed to breed and carry on the line. Their distinctive shape is evident even in newborns.
