Atrypa reticularis with lophophore

This fossil is chipped which revealed what looks to be its feeding apparatus or lophophore. The Silurian Period brachiopod is probably a Atrypa reticularis. It was found in the Waldron Shale of Clark County, Indiana.

Calymene celebra Fossil

This Silurian fossil is a Calymene celebra. It was found in the Racine Formation of Milwaukee County, Wisconsin. Such nice preservation and it reminds of trilobites found in the dolomite around Bardstown, Kentucky.
Thanks to Nathan for the fossil.

Meekoceras Ammonoid Fossil

This ammonoid fossil appears to be a Meekoceras sp. It was found in the Thaynes Formation of Salt Lake County, Utah. It dates to early Triassic Period.

Thanks to Nathan for this fossil. Recently, he visited the Louisville area with a group of students from the University of Wisconsin and we exchanged some fossils. They were very dedicated and impressive in their fossil searching capabilities. We visited a number of local sites and collected for hours in the rain, sleet and snow. Brrr, it was cold and wet. Lots of neat fossils were found, including a Silurian cystoid, a spiny brachiopod, trilobite segments, a giant snail, colonial coral colony, and lots of ziplock bags of fossils. After Louisville, they had more areas to visit around the midwest to find fossils at.
