Devonian Period Plants

Devonian Period (about 416 to 359 million years ago) plants found in the New Albany Shale. These fossils are on display at the Indiana State Museum.


This first two fossil images are of a Callixylon newberryi trunk fossil.  More than likely the tree trunk floated into an area of Indiana and then sank.  Over time the trunk became fossilized.



 

These last two images are of what might be a Calamites in the New Albany Shale.  The Calamites has a relative alive today referred to as Horsetails.
