sedimentary rock
Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.
Igneous rocks and most metamorphic rocks, of an igneous origin.
The Badlands in Badlands National Park contain reptile fossils (including alligator fossils), but do not contain dinosaur fossils. Note that "Badlands" refers to a type of geographical feature, which is not only found in Badlands National Park.
Chert is a type of microfibrous sedimentary rock which contains small fossils. Alibates is exposed flint, it was used by prehistoric hunters.
When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber. Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolite are trace fossils - they show us how an animal lived.

Though somewhat rare, either rock type could contain fossils.

Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.
The Badlands in Badlands National Park contain reptile fossils (including alligator fossils), but do not contain dinosaur fossils. Note that "Badlands" refers to a type of geographical feature, which is not only found in Badlands National Park.
It would necessarily be sedimentary rock, formed in a saltwater or freshwater environment, depending on the type of clam.
Chert is a type of microfibrous sedimentary rock which contains small fossils. Alibates is exposed flint, it was used by prehistoric hunters.
