This specimen came from eroded limestone. It was very light and fragile. The sections averaged about 2.5mm in width. Identification currently is unknown, however it does appear to be a straight shelled species.
Eroded Limestone
Most of the limestone exposed to the outside environment has an eroded edge. I am currently not sure what causes this, however I am going to guess it’s the acidity of the rain and perhaps UV radiation from the sun. Fossils can be easy to find in this type of rock, but they can feel like they are made of dirt or sand. The hard limestone further in is in my opinion one of the hardest rocks I have had to break apart.
