Clams and Fiddleheads in a Pennsylvanian Age
Clams cooked in a ramp sauce with fiddlehead ferns and asparagus.
When out exploring the majesty of the forests and streams in our Penn's Woods this Summer, don't forget the rich often forgotten world of ages past. Snapshots in time, not with modern technology, but preserved in rock. I'm talking about fossils of course. While you won't dig up any dinosaur bones in PA, there are certainly interesting finds to be discovered.
There is even a geologic age, a sub period of the Carboniferous Era, named -The Pennsylvanian.
The booklet produced by the - Common Fossils of Pennsylvania- says "Plant fossils are found in many parts of Pennsylvania in the rocks and coal that formed in extensive swamps during the geological period of time called the Pennsylvanian Period (330 to 290 million years ago) "
You can also find many other corals, mollusks, gastropods, and arthropods. Our state fossil is the trilobite if you didn't know.
The fossils found by above show an abundance of life; they could possibly be one of the most common fossils found in PA, called Brachiopods. These were clam -like creatures, but not related to clams and mollusks, that covered much of the ancient sea floors in the Paleozoic Era, now there are only a few species left.
So this Summer, be on the look out for fossils and contemplate what life was like millions of years ago in the swamps and the seas of Pennsylvania.
Remember to fossil hunt responsibly and look up the for more information.
