**Title:** “An Army of Rhinos”
**Description:** The image illustrates five extinct rhinoceros species, highlighting their evolutionary diversity across different time periods. The background features a light green-to-beige gradient with a central gray scale bar. Each rhino is shown in a side profile, walking rightward, with labels noting their name, time period, location, and existence timeline.
1. **Hyrachyus eximius**
– Time: 46.2–40.4 million years ago (mya)
– Location: US
– Description: A small, slender rhino with a spotted brown-and-white coat, resembling a dog-horse hybrid. It has a long tail, thin legs, and no horns.
2. **Diceratherium armatum**
– Time: 20.6 mya
– Location: US, Canada
– Description: A medium-sized rhino with a solid brown coat, two small side-by-side horns on its snout, a short tail, and thicker legs.
3. **Hispanotherium matritense**
– Time: 20.5–12.7 mya
– Location: Spain, China
– Description: A larger rhino with a light beige coat, a single prominent horn, an elongated body, a slightly arched back, sturdy legs, and a short tail.
4. **Sinotherium lagrelii**
– Time: 16.9–2.5 mya
– Location: China, Russia, Kazakhstan, Tajikistan
– Description: A large, gray-skinned rhino with a single large horn, a massive body, rounded belly, thick legs, wrinkled skin, and a short tail.
5. **Elasmotherium sibiricum**
– Time: 2.6 million years ago to 29,000 years Before Present (B.P.)
– Location: China, Moldova, Russia, Ukraine
– Description: The largest rhino, with a thick, woolly brown coat, a massive single horn on its forehead, a humped back, robust build, sturdy legs, and a short tail.
**Top Text:**
“Living rhinos are generally associated with big horns, thick hairless skin and tropical habitats. But their ancestors didn’t always fit that description, with some living far up north and sporting luscious coats. The animals represented here are not to scale and don’t represent a direct line of descent, but rather plausible models for how this amazing transition happened.”
