The extinction was caused by climate change. The main cause of extinction was the vast amount of carbon dioxide emitted by volcanic eruptions that created the Siberian Traps, which elevated global temperatures and acidified the oceans.

The Painted Hills are one of the three units that comprise the John Day Fossil Beds. Take time to also visit the Clarno Unit, with Mars-like pillars formed by waterfalls and volcanic sludge, and the Sheep Rock Unit, where fossils of plants and animals like saber-toothed cats are on display at the Thomas Condon Paleontology Center. The hills get their name from the delicately colored stratifications in the soil and the yellows, golds, blacks and reds of the Painted Hills are best seen in the late afternoon. Tones and hue may appear to change from one visit to another, as the claystone differ with ever-changing light and moisture levels. Once you see them for yourself, it’s pretty easy to understand why the Painted Hills are one of the 7 Wonders of Oregon.
