Burial in sediment
They are called fossils.
A fossil is any evidence of an organism preserved in rock.
A fossil is any trace of an organism preserved in a rock.
These small particles are known as clasts. If they are the remains of living things they may be known as bioclasts. The remains of animals are called fossils if they have hardened and become preserved.

FOSSILS
A fossil is any evidence of an organism preserved in rock.
They are generically called fossils.
A fossil is any evidence of ancient life that is preserved in stone or other material. Fossils can include molds, casts, defecation material, stomach stones, bones, footprints, trails and burrows. Fossils can be preserved in sedimentary rock (and rarely metamorphic and igneous rock), tar pits, and amber, and are usually the result of the organism being covered rapidly upon death. Fossils are very important in helping us trace the history of life on Earth and the evolutionary relationships between organisms of the past and present.
When ancient animals and plants died, their bodies might be covered in silt, mud, sand, etc. Over an extremely long time, the sediment may be turned into sedimentary rock. The preserved remains are what we know as fossils.
A sedimentary rock forms from rock particles cemented (compacted) together. If the remains of dead plants and animals are preserved in the rock, they become fossils. If the remains break down into carbon, oils, or gases, they become fossil fuels.
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
