Polystomella aculeata Foraminifera

UPDATE: I am pretty sure my earlier identification is incorrect. I now think this might be an Elphidium aculeatum (Polystomella aculeata).

This looks like a Nerotalia calcar foraminifera. It was found at Pago Beach on the island of Guam. Image is magnified 40 times under a microscope which should equate to a 1 mm field of view.

Thanks to Pam for obtaining the specimen and Herb for the processed material.

Platyceras and Acanthocrinus Fossilized Spines

This piece of Devonian Period limestone is from the Jeffersonville layer of Clark County, Indiana. It is unique in that it contains spines from two types of creatures: snail and crinoid. The solid spines are from the Acanthocrinus or Gilbertocrinus while the hollow ones might be from the Platyceras snail.

Thanks to Kenny for the picture.

Flexicalymene meeki Trilobite Fossils

Enrolled Flexicalymene meeki trilobite fossils found in Franklin County, Indiana. These creatures scurried along the sea floor back in the Ordovician Period.
