Along the road towards Jim Pond are occasional pockets of fairly good slate. I worked this outcrop to cover my driveway.
Here and there you find very big to small rounded and angular blocks of mudstone containing marine fossils
Take time to look at the beauty around you
I think that this fossil is a small species of Placoderm but this needs to be verified. 450 millions of years during the Silurian period, this dorsal, bony armor of a very primitive fish left its remains in the mud coffin. Placoderm had the distinction of being the first to have an articulating jaw, although without teeth. It grew to a length of 30+ feet. It was a terror in the ocean.
Mud cracks on a bed of mudstone. Several times within 450 to 250 million years, the mountains eroded, the land beneath rebounded and lifted the underlying plate, and the new mountains eroded again--all resulting in new beds of sands and silt depositions in the tropical coastal areas (near Africa) and the transgression (invasion) of the ocean on land followed by ocean retreats as the mountains reformed. Here is mud cracks in a mudstone bed testifying to these events which preserved through time for us to enjoy in the Stratton vicinity.
