| Notes | The Yaquina Formation was deposited in Western Oregon at the end of the Oligocene period and the beginning of the Miocene. There were three major depositional events, two in shallow marine environments, and one on land. The later deposits were formed on a delta of the ancestral Yaquina River, and provide a unique look at what life was like on land about 25 million years ago. Although there are a few animal fossils in this Middle Non-Marine Member, the overwhelming majority of fossils are of plants, and they are the subject of this most interesting Master’s thesis. The fossil record points to a major warming event at the time, and the author finds the Yaquina flora resembles “a marginally subtropical evergreen broad-leaved forest” with abundant climbing vines (p.65). |
