Petrified Pine Cone

 

 

 
  
May's designated Fossil of the Month is this frozen-in-time pine cone! One specimen we have on display is complete and still in matrix, while the other has been cut and polished to get a look at the interior of these prehistoric cones. 
 
The ancient Araucaria tree was a coniferous tree that grew in Patagonia, Argentina. During the Jurassic period, a volcanic eruption buried the forest, preserving the wood and pine cones. Some petrified trunks measure over 300 feet in length.
