Echinocorys sulcatus Echinoid Fossil

This fossil might be the first one I ever posted from Denmark. The label that came with it listed Dalbyover, Denmark. It appears be an Echinocorys sulcatus from the Paleocene (Danian). See the Fossils of NJ web site for more information: fossilsofnj.com/coppermine/displayimage.php?pid=39

Thank you to Dieter Ketelsen of Hamburg, Germany for this specimen. Much appreciated! Thanks to Michael at foraminifera.eu for transporting the specimen and the identification link.

Pentremites obesus Blastoid

Pentremites obesus blastoid found in Grayson County, Kentucky, USA. Fossil was picked up in the Glen Dean Formation which dates to the Upper Mississippian Period (Carboniferous). For blastoids, this one is large measuring about 3 cm across. Thanks to Herb for letting me photograph it.

Prepped Calymene breviceps Molts

Probably the most commonly found trilobite in the Waldron Shale of Indiana, the Calymene breviceps. These two fossils appear to be molts which were shed during the Middle Silurian Period (about 425-420 million years ago). See some more outstanding prepared trilobites like this one at the Weeks Trilobite web site.

Thanks to Mark for letting me photograph these.
