Fossil leaves from Emerald Creek * Early Miocene of northern Idaho
Platanus and Zizyphoides
| These photos show some examples of fossils that occur at the Middle Miocene Emerald Creek locality of northern Idaho. On the left is a sycamore leaf (Platanus; Platanaceae). These leaves can get to be quite large at this locality. |
| On the right is Zizyphoides, the leaf of the Nordenskioldia plant, an extinct genus in the Trochodendraceae. Note the long petiole and lobed leaf margin. Zizyphoides-type leaves and Nordenskioldia are known from numerous Tertiary localities, including the Paleocene Almont flora of North Dakota and the middle Eocene flora of Republic, Washington.. |
