Tree of Heaven - Ailanthus confucii

Eocene (52.3 Million Years Ago) 

In Stone Fossils Private Quarry 

Green River Formation, Wyoming 

Tree of Heaven - Ailanthus confucii

Order Sapindales, Family Simaroubaceae
There are about 100 modern species in the Simaroubaceae family, found primarily in tropical and subtropical regions. The Ailanthus genus has a disputed number of living species, somewhere between 5 and 10. They are commonly known as "Trees of Heaven."
A. confucii is:

  • a winged fruit
  • characterized by its centrally located seed
  • known from fossil deposits in North America, Asia, and Europe
  • found almost exclusively in lake and pond deposits

A. confucii specimens from the FBM are the oldest known representation of the Simaroubaceae family in North America, possibly the world.

 

Plants are major indicators of climate. Fossil leaves and plants act as ancient thermometers, allowing scientists to study the ancient climate of Fossil Lake. It is difficult to identify fossil leaf specimens from the Fossil Butte Member (FBM) at the species level.
