Description

Seed
Early Eocene
Green River Formation
Kemmerer, Wyoming, USA

23mm seed on 47mm slab from the “split fish” layers.

Here is an unidentified seed from a locality famous for fishes from a lake long gone.

The Early Eocene was the warmest interval since the days of the dinosaurs.  Tropical forest covered much of the continents.  Even Antarctica was ice-free at the time.  Climates would start to trend cooler a few million years later.
