The material comprising the rocks coal and limestone are derived from organisms. Therefore, they are classified as organic sedimentary rocks.
sedimentary rocks can be classified by detrial, chemical ,or organic
Kaibab Limestone is not an organic sedimentary rock, but classified only as a sedimentary rock. Organic sedimentary rocks form from the remains of carbon rich plant life normally.

Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.
Examples of organic sedimentary rocks include coal, which forms from the accumulation and compaction of plant remains, and limestone, which can contain organic debris such as shells and coral. Organic sedimentary rocks are derived from the remains of living organisms.
Sedimentary rocks formed from living or once-living material are called organic sedimentary rocks. Examples include limestone, coal, and chalk.
Sedimentary rocks are classified into three main types based on their formation processes: clastic, chemical, and organic. Clastic sedimentary rocks are formed from the accumulation and compaction of mineral and rock fragments, such as sandstone and shale. Chemical sedimentary rocks result from the precipitation of minerals from solution, exemplified by limestone and rock salt. Organic sedimentary rocks, like coal, form from the accumulation of plant or animal debris.
Crystalline limestone and chert are classified as biochemical sedimentary rocks. Crystalline limestone forms from the accumulation of calcite-rich remains of marine organisms, while chert forms from the silica-rich remains of marine organisms such as radiolarians or diatoms.
Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
Marble, the rock, is metamorphic. From limestone.
Granite, shale, coal, and limestone are commonly known as types of rocks. Granite is an igneous rock, shale is a sedimentary rock, coal is a sedimentary rock that forms from organic matter, and limestone is a sedimentary rock composed mainly of calcite.
