Explain your answer. The hard shell of a clam is more likely to fossilize because it is more resistant to biological and environmental destruction. For this reason, teeth, bones and other hard parts of organisms are much more numerous in the fossil record than soft tissues.
Why is a mammoth more likely to fossilize than a caterpillar?
Why is a mammoth more likely to fossilize than a caterpillar? Hard parts like bones and teeth are more likely to be preserved. Rapid burial is important in the fossilization process because: It protect a dead organism from physical and biological destruction.
Where would you expect fossils to be most likely preserved?
Since rapid burial in sediment is important for the formation of fossils, most fossils form in marine environments, where sediments are more likely to accumulate.
What are the 3 most common fossils?
According to “Enchanted Learning,” archaeologists use three main types of fossil: the true form fossil, trace fossil and mold fossil; a fourth type is the cast fossil. Fossilization can take millions of years to occur.
What is least likely to become a fossil?
Organisms without hard parts are the least likely to be fossilized.
What are the 5 types of fossils?
Five different types of fossils are body fossils, molds and casts, petrification fossils, footprints and trackways, and coprolites.
What fossils can show about Earth’s history?
We only know about extinct groups like dinosaurs, ammonites and trilobites through fossils. Some animals and plant are only known to us as fossils. By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other.
What rocks are fossils found in?
Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.
Why do we not use the K CA system for dating potassium bearing rocks?
Calcium is not found in potassium-bearing rocks. c. Most calcium found in rocks is naturally present and not the result of radioactive decay of potassium. … The K-Ca decay has too short of a half-life to be useful for dating rocks.
What 4 things do Fossil records show?
Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
What are the rarest fossils to find?
It’s hard enough to find fossils of hard things like dinosaur bones. Now scientists have found evidence of 95 million-year-old octopuses, among the rarest and unlikeliest of fossils, complete with ink and suckers.
What are the most popular fossils?
Lucy, a 3.2 million year old Australopithecus afarensis named after the Beatles’ song “Lucy in the Sky with Diamonds”, is perhaps the most famous fossil in the world.
Do all bones fossilize?
Bones, teeth, shells, and other hard body parts can be fairly easily preserved as fossils. However, they might become broken, worn, or even dissolved before they are buried by sediment.
What are 3 ways in which a fossil can be destroyed after it has formed?
Once fossils are formed, they might be washed away by streams, moved by glaciers, carried by scavengers, or caught in rockslides. Weathering by wind, water, and sun can destroy a fossil by wearing it away.
What rock is most likely to contain fossils?
Almost all fossils are preserved in sedimentary rock.
