On this my 79th Birthday, I have a desire to reconnect with some fossils that I found while in high school near my home at the time in Ellwood City Pa. Those fossils are long gone donated to schools. I recall finding a number of brachiopods and what I believed to be a shark tooth (never had it formally ided) If anyone has a collection from the Vanport, I would be delighted to see pictures posted and maybe when life resumes trade for some fossils. The Vanport was used in making Portland cement and there were a number of companies. Later in life I tried to collect again but the quarries I knew w

Crinoid Stem Piece - Arizona Naco Formation, Arizona Pennsylvanian age (Desmoinesian to Virgilian,310 to 304 Million Years Ago) Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). The name comes from the Greek word krinon, "a lily", and eidos, "form". They live in both shallow water and in depths as great as 9,000 meters (30,000 ft). Those crinoids which in their adult form are attached to the sea bottom by a stalk are commonly called sea lilies. The unstalked forms are called feather stars or comatulids. -

Calamites Fossil Blue Creek Seam, North central Alabama Pennsylvanian Age (~ 320 Million Years Ago) A number of organ taxa have been identified as part of a united organism, which has inherited the name Calamites in popular culture. Calamites correctly refers only to casts of the stem of Carboniferous/Permian sphenophytes, and as such is a form genus of little taxonomic value. There are two forms of casts, which can give mistaken impressions of the organisms. The most common is an internal cast of the hollow (or pith-filled) void in the centre of the trunk. This can cause some confusi -

This is Pennsylvanian age Mazon Creek type material found in Indiana. Not sure if even a genus can be assigned to this piece let alone a species but I thought it was worth letting you guys have a look.This appears to be outer bark with small carbon film leaf scars overlying exposed patches of inner bark. Any thoughts would be appreciated.

I found a nodule today that had a natural fracture so I tapped it with the hammer and I think it is most of a fish.. The only pic that is taken without a loupe is the one with the key.. I am wondering if it's possible to tell what is the front of the fish and which is the back.. Unfortunately it is in rough shape (some of it). I cannot tell because I see small fin areas in several places.. Is it the fish minus the head? Thanks!
