Yes, sedimentary rocks often contain shells and skeletons of marine animals. These fossils form when sediments accumulate and lithify, preserving the remains of organisms that lived in aquatic environments. Common examples include limestone, which can contain fossilized coral and shell fragments, and shale, which may include tiny shells or remnants of marine life. The presence of these fossils provides valuable insights into the Earth's history and past ecosystems.
What else can I help you with?
Sedimentary rocks that are formed partially by animals and plants are called what?
Sedimentary rocks that are formed partially by animals and plants are called organic sedimentary rocks. These rocks are formed from the accumulation and lithification of the remains or traces of once-living organisms. An example of an organic sedimentary rock is limestone, which is formed from the accumulation of marine organisms' shells and skeletons.
Biogenous sediments are shells and skeletons of marine animals and algae what are two examples of this?
Two examples of biogenous sediments are foraminifera shells and diatom skeletons. These materials accumulate on the ocean floor over time and contribute to the formation of sedimentary rocks like limestone.
What is lithified of tiny marine organisms with skeletons composed of silica?
Diatoms are tiny marine organisms with skeletons made of silica. When these diatom skeletons accumulate and become cemented together over time, they form a type of sedimentary rock known as diatomite or diatomaceous earth.
Is limestone made from clastic organis or chemical?
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
What is the origin of chert?
The origin of chert in sedimentary rock formations is silicon derived from siliceous skeletons of organisms or silicon solutions replacing voids or entombed animals or plants in the formations.
What 3 kinds of sedimentary rocks make up coquina?
Coquina is a sedimentary rock made up of shells, shell fragments, and skeletons of small marine creatures.
Cemented shells of marine organisms form which kind of sedimentary rock?
The cemented shells of marine organisms form limestone, which is a type of sedimentary rock. Limestone is predominantly composed of the mineral calcite and can contain fossilized remains of shells and other marine organisms.
What is radiolarian in geology?
Radiolarians are single-celled marine organisms that secrete intricate silica skeletons. When these organisms die, their skeletons sink to the ocean floor and can become preserved as radiolarian ooze, which eventually turns into chert, a type of sedimentary rock. Radiolarian fossils are important for dating and understanding ancient marine environments.
What is a type of sedimentary rock formed from skeletons of microscopic living things once in the ocean?
Organic Sedimentary rock would probably be the best answer!
What sedimentary rocks are formed from the remains of plants and animals?
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.
WHAT ARE two types of sedimentary rocks and describe what they are made from?
Two types of sedimentary rocks are sandstone and limestone. Sandstone is made from grains of sand that have been compacted and cemented together, while limestone is primarily made from the accumulation of the shells and skeletons of marine organisms.
Which type of material does biogenous sediment form?
Two types of biogenous sediments are calcareous ooze and siliceous ooze.
