Sclerocormus parviceps

This whip-tailed marine reptile was an ancient relative of the dolphin-like ichthyosaurs. It dwelled the seas of early Triassic, right after the extinction that wiped out more than 90% of all marine species.

Sharovipteryx mirabilis

Sharovipteryx is the only reptile found so far with wing membranes on its legs instead of its arms. This peculiar anatomy was probably inherited from long-legged climbers that leaped from trees to trees.

Sinosauropteryx prima

It was the first non-bird dinosaur to be found with evidence of feathers. The first Sinosauropteryx fossil found shows the typical "dinosaur death pose" caused by contraction of muscles and ligaments after death.

Smilodon

The saber-tooted cat was a predator that lived in the Americas during the Pleistocene Epoch. It preyed on large herbivores like bison and camel until they all went extinct around 10,000 years ago.

Stegodon

This extinct elephant relative was one of the largest in its family tree, reaching up to 3.9 meter (12.7 ft) tall. Interestingly, some small species from the island of Flores, Indonesia, shrunk to only a third of that size.

Stegosaurus

Stegosaurs are some of the most instantly recognizable dinosaurs to the general public. They are well known for their distinctive anatomy, especially the large flat plates that covered the neck, back, and tail, the four or more large spikes at the end of the tail, and ocassionally, large spikes arising from their shoulders.

The males of this species were armed with Y-shaped horns that grew above its snout. Such a strange forked structure could have helped them settle territorial disputes.
