Description

Late Oligocene

Fisher Formation

Goshen, Lane County, Oregon, USA

71mm leaf on 106mm slab

Leaf,

Here’s a fine leaf nicely-centered in matrix.  It’s a great piece to add to a fossil display.

During the Late Oligocene, climates were cooler and sea level was lower worldwide just before a warming trend in the Early-Middle Miocene.  Climates would trend cooler again during the Late Miocene culminating in the ice ages of the Pleistocene.
