92mm leaf on 127mm slab.

Leaf,

Here’s a leaf fossil from a time when 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.

A fossil leaf makes a great gift for the novice or casual science enthusiast.
