6.3" Plate Of Fossil Leaves Preserved In Travertine - Austria

These are very detailed fossil leaves preserved in travertine, collected in the Tirol region of Austria. Travertine is a form of limestone deposited by mineral springs, especially hot springs. Basically hot springs deposited layer upon layer of limestone on the leaves, preserving them as fossils. The deposits have been dated to ~ 12,000 years ago. The largest leaf is 3.7" long.
