The border between light and dark was sharp and fairly high up. This type of #countershading is seen in modern animals that live out in the open where they& #39;re often in direct sunlight. With this in mind we can infer that S. prima lived out in the open too!

Oops, forgot to mention the stripey tail. It was very stripey
