A calcarenite is a form of limestone composed of sand-sized grains derived from the erosion of other rocks.

A biocalcarenite is a calcarenite which contains fossils.
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.
One way to distinguish between the samples is to examine the grain size and texture: calcarenite fossiliferous limestone typically has larger grains and a coarser texture compared to the finer grains and smoother texture of carbonite mudstone with fossil shells. Additionally, conducting a chemical test such as a reaction with acid can help differentiate between the two types of rock, since limestone will fizz when it comes in contact with acid due to its calcium carbonate content.
The stone that forms from coral is called limestone, specifically a type known as calcarenite or coral limestone. This sedimentary rock is created when coral reefs, composed of calcium carbonate from coral polyps, accumulate over time and undergo lithification. The process often involves the compaction and cementation of coral fragments and other marine organisms, resulting in a durable rock that can be found in various geological formations. Coral limestone is significant for its role in marine ecosystems and its use in construction and decoration.
