FOSSIL TREE FROM RED DEER RIVER, ALBERTA 



This petrified tree trunk, now on exhibition in the dinosaur hall of the American Museum, is forty- 

 five, feet long. It is in a fine state of preservation. Many fossilized trees, chiefly cone-bearers, are found 

 associated with dinosaur skeletons on the Red Deer River. They are carbonized and jet black. When 

 found they are surrounded with a thin layer of lignite, which soon disintegrates under exposure, while 

 the central silicified stem bleaches to a reddish bufif color
