Fossil Sponge in Ice


Here is a very fresh find from the Waldron Shale. This morning it was below freezing in the Louisville area. This fossil appears to be a Receptaculites subturbinatus. It was found in Clark County Indiana USA and dates to the Silurian Period. I might have some better pictures later once it thaws out.

Thanks to Kenny for the image.

Modern Brachiopod



This specimen came from the Dr. James Conkin collection. It had no label and I suppose was used for teaching purposes to show what a non-extinct species of brachiopod looked like. It definitely looks like a lamp shell. At first I thought it might be easy to figure out its name but now I am not sure. It might be a species of Laqueus. I know some are found off the coast of California. My next idea was to look at images I took at the American Museum of Natural History in New York. They had a picture of a lamp shell called Liothyrella notoreadensis that look similar to this one. They had several containers on display with no names so these creatures are a lot more diverse than I realized.


So I am not sure where it is from or its exact name.
