Clam shells are sedimentary rocks but not until they are fossilized.
Rocks formed from sand, rocks, and shells are known as sedimentary rocks. Sandstones, mudstones, and limestone are common examples of sedimentary rocks that can be formed from these materials.
Sedimentary rocks made from fragments of rocks, minerals, and shells are known as clastic sedimentary rocks. Examples include sandstone, shale, and conglomerate. These rocks form when pre-existing rocks are weathered, eroded, transported, and deposited in layers.
They are called clastic sedimentary rocks.

Clastic and nonclastic

Sedimentary rocks made from fragments of rocks, minerals, and shells are known as clastic sedimentary rocks. Examples include sandstone, shale, and conglomerate. These rocks form when pre-existing rocks are weathered, eroded, transported, and deposited in layers.
Clastic sedimentary rocks are made of fragments from rocks, minerals, and shells. These fragments, called clasts, are compacted and cemented together over time to form rocks like sandstone, shale, and conglomerate.
There are different ways sedimentary rocks are formed. Many sedimentary rocks are made from the broken pieces and particles of other rocks, [which is a reason why the name was given to these types of rocks (sediment)] and these bits get cemented together. These types of sedimentary rocks are called clastic sedimentary rocks. Chemical sedimentary rocks are another type that comprise of mineral crystals, like gypsum and halite. Lastly, organic sedimentary rocks are made of, well...... organic materials. They are made of the remains of once living organisms and contain the remains of living creatures such as clam shells, plankton skeletons, dinosaur bones, and plants.
The class of sedimentary rocks made of fragments of rock minerals and shells is known as clastic sedimentary rocks. These rocks form from the accumulation and lithification of sediments such as sand, silt, clay, and sometimes organic material. Examples include sandstone, shale, and conglomerate.

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.
The "solid rocks" are sedimentary rock - they started out as the bottom of lakes, streams and rivers. That's where you find shells.
