Fossil Plants from Pennsylvania

My friend Shamalama (username on The Fossil Forum website) sent me some pictures of recent finds from St. Clair, Pennsylvania. These plants grew in the Late Carboniferous or Pennsylvanian Period and can be found in the Llewellyn Formation.

St. Clair is famous for the white appearance of their plant fossils which caused by aluminum silicate or pyrophyllite. This first fossil is Alethopteris.


This second fossil is a Asterophyllites. It could be of the species Asterophyllites charaeformis.

This next fossil is a Sphenophyllum.


This last fossil plant is unidentified.

Australian Brachiopods & Clams

Here are some pictures sent to me by Bill in Australia. Here are some unidentified brachiopods and clams in mudstone or shale. They have a nice brownish-red color.

These fossils were found in southeastern Australia. They might be Ordovician Period.

It is always good to see fossils from different regions of the world.
