Fossils

True. In an undisturbed sequence of sedimentary rocks, the bottom layer is the oldest and the top layer is the youngest due to the principle of superposition, which states that in any undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest are at the bottom.

Mold is related to cast because they are types of fossilizations, where the physical characteristics of organisms are impressed onto rocks. Most impressions occur in coarse porous rocks such as sandstones.

What do you mean by "partially evolved"? Since evolution is an ongoing process, any existing species will always be in a state of change. If you're referring to intermediate forms, some of the best examples to have been found in recent years are various fossils that show characteristics of both dinosaurs (scales, teeth, claws on all 4 appendages) and birds (beaks and feathers). Check out a site such as www.NewScientist.com for articles that are understandable without needing a graduate degree in paleontology.

Organisms in the rainforest are typically decomposed rapidly by bacteria, fungi, and insects, preventing fossilization. The warm and humid conditions of the rainforest accelerate decay processes, leaving little time for the necessary conditions for fossilization to occur. Additionally, the dense vegetation in rainforests makes it challenging for fossils to be exposed and preserved.

Yes, mammal fossils can be found in rocks. They are typically found in sedimentary rocks, such as limestone or shale, where the remains of ancient animals have been preserved over time. These fossils provide important insights into the evolution and history of mammals.

A fossil type characterized by an open space left inside a rock by an organism that has decayed is called a mold fossil. Mold fossils are created when the organism decomposes and the impression is preserved in the sediment that surrounds it, leaving behind a cavity in the shape of the organism.

Fossils can make materials like fossilized limestone or marble attractive to architects due to their unique patterns and historical significance. The presence of fossils in the material provides a natural and visually interesting texture that can add character to buildings and bring a sense of timelessness to design.

Geologists can learn about the Earth's history, past environments, and changes in climate by studying fossils. Fossils provide evidence of how life has evolved over time and can help geologists understand the geological processes that have shaped the planet. They also help in dating rocks and determining the age of different geological formations.

Fossils encased in amber or ice are well-preserved, offering unique insights into ancient ecosystems and organisms. The amber fossils often capture minute details due to the clarity and protection provided by the resin. Ice fossils can include soft tissues and DNA that are usually not preserved in other types of fossils due to rapid freezing.

Another kind of fossil is a mold or cast fossil, which forms when an organism's remains decay and leave an impression in the surrounding sediment that is later filled with minerals. Another type is a trace fossil, which is evidence of an organism's activity, like footprints or burrows, preserved in rock.

An archaeologist studies past human life by examining artifacts, while a paleontologist studies ancient life forms by studying fossils.

Well if you mean looking for fossils and such then it is paleontologists.

The earliest remains of humans were found in Africa and are about 300,000 years old. These early fossils belong to Homo sapiens, our species. They provide important insight into the origin and evolution of modern humans.

The timeframe varies by jurisdiction, but typically a complaint becomes public information after probable cause has been found and the defendant has been formally charged or arraigned in court. This process usually happens within a few days to a couple of weeks of probable cause being established.

Fossils are not living because they are the preserved remains or impressions of organisms that lived in the past. Over time, minerals replace the organic material of the organism, turning it into rock-like structures. This process effectively "freezes" the organism in time, making it no longer alive.

No, growth rings are not typically found on living clam shells. They are commonly found on fossil clam shells and can provide information about the age and growth patterns of the clam when it was alive.

Yes, fossils are relatively rare because specific conditions are needed for the preservation of organic material over millions of years. Factors like rapid burial, lack of oxygen, and the presence of minerals play a crucial role in the formation of fossils. Due to these requirements, many organisms never fossilize, making the discovery of fossils a rare event.

A very old fossil in sedimentary rocks is called a "trace fossil" or "index fossil." These fossils provide valuable information about past life forms and help scientists understand Earth's history.

You can purchase authentic Fossil watches at a variety of places. Many retailers, such as Kohl's, Sears, Macy's and JcPenney, sell Fossil watches. Even discount stores, such as Ross and Marshalls, carry Fossil watches every once in a while, and they are often cheaper than the prices you see at a department store.

You can find a rock pool along the coastline where rocks and tide pools form. These natural formations are typically found in intertidal zones, where the ocean meets land, and are known for containing various marine life such as crabs, snails, and small fish.

The first dinosaur fossil was found in Haddonfield, New Jersey, USA in 1858. It was the Hadrosaurus foulkii, a duck-billed dinosaur.

Fossil remains are the preserved traces or remains of ancient organisms, such as bones, teeth, shells, or imprints of organisms in rocks. They provide valuable information about the history of life on Earth, allowing scientists to study and understand the evolution of various species over time. Fossils help to reconstruct past environments, identify extinct species, and provide evidence for evolutionary processes.
