If that easily worked, then Mother Nature would have released lots of calcitic fossils from pure limestone. If the matrix has lots of mud in the limestone, I have heard that lye flakes may selectively break up the mud, but not touch the calcite. In other words, you may be able to extract calcitic fossils from muddy marls. Edited June 27 by DPS ...

Calcite is a versatile mineral treasured by lapidarists for its beautiful forms and dazzling colors. As a relatively soft mineral with a Mohs hardness of 3, calcite may not be suitable for all jewelry applications, but its variability makes it perfect for artful lapidary work. The most prized calcite specimens feature brilliant crystal formations, like the …

The rock layers comprise Black Rock Limestone which was formed in the Carboniferous Period. At some time in the past, cracks opened up in the rocks, breaking it at right angles to the rock layers. These fissures became filled up with calcium from solution in ground water that precipitated out as large calcite crystals on the sides of the spaces.
