| A Sequoia twig from the upper Eocene Dead Horse Tuff, Copper Basin, Nevada--from an extinct genus-species of Sequoia paleobotanists refer to as Sequoia affinis, whose closest modernday counterpart is the coast redwood. The fossil plant is 38 to 39 million years old. A screen shot from a video uploaded to YouTube by Crime Pays But Botany Doesn't; I edited and processed the image through photoshop. |
