4.5" Mississipian Fossil Microbial Mat - Bear Gulch Limestone
This is a slab of a 320 million year old microbial mat from the Bear Gulch Limestone in Montana. While collected the formation this summer one of our partner companies encountered a single bedding plane covered in this fossilized microbial mat. They collected some of it and cut it up into interested sections such as this piece. Comes with an acrylic display stand.
