Here's More Information....Fifty-million years ago an ancient Lake existed in what is now southwest Wyoming!

The resulting laminated limestone contains the highest concentration of articulated fish fossils in the world!
The leaf fossil measures a crazy! 11.2cm or or 4/3/8" overall piece or matrix measures a BIG! 29.7cm or 11.5" at their biggest or from opposing side to side! Please note that a used display STAND is included.
