How would you distinguish a sample of calcarenite from a sample of mudstone with fossil shells?
Calcarenite has sandsized shell fragments and sometimes a few larger whole fossil shells. Mudstone is mostly comprised of silt or clay and may or maynot contain fossils, the mudstone will break, fissil, or crumble.
What is hard mudstone?
Hard mudstone is a sedimentary rock composed mainly of clay and silt particles that have compacted together over time.

Hard mudstone often has a fine-grained texture and can appear as dark gray, black, or brown in color.
Is mudstone igneous or sedimentary?
