Why shark teeth are often found as fossils but impression of jellyfish are rarely found?
Because shark teeth are hard enough to be fossilized
How were jellyfish fossils found?
Jellyfish fossils have been found in sedimentary rock formations around the world, generally in areas where ancient seas once existed. The soft-bodied nature of jellyfish makes their preservation as fossils rare, but in some cases, the impressions left by their bodies in sediment have been preserved and fossilized over millions of years. Scientists use careful excavation techniques to uncover and study these fossils to learn more about the evolution and history of jellyfish.
Would you find a jellyfish fossil?
It is possible to find jellyfish fossils, but they are rare because jellyfish have soft bodies that are not easily preserved. In some cases, fossilized impressions of jellyfish have been discovered in certain types of sedimentary rocks that have preserved their soft tissue.
Why are jellyfish rarely found fossilized?
They have no bones.
Why are fossils rarely found?
They have no bones.
In rock layers jellyfish fossils are found lower than trilobite fossils and trilobite fossils are found lower than ammonite fossils. What can be determined from this information?
From the information provided, it can be determined that jellyfish are older than trilobites, and trilobites are older than ammonites. This suggests a chronological order of these organisms in the fossil record, with jellyfish appearing first, followed by trilobites, and then ammonites. This pattern aligns with the principles of stratigraphy, where older fossils are found in lower rock layers.
For which segment of the Earth's geologic history are fossils rarely found?
precambrian
Are fossils abundant in all types of rocks?
no they are not. If you go outside and look around and look at all types of rocks you will probably not find a fossil. Fossils are rarely found.
What is the age of fossils that can be measured by what dating?
Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found
How do you get to know that dinosaurs once existed?
I know about dinosaurs from reading about them, watching documentaries, and a visit to a natural history museum to see dinosaur fossils in person. Scientists learned about dinosaurs by studying fossils, including bones, skin impressions, and footprints, and the rocks the fossils were found in.
What is the definition for fossil?
Fossils are the preserved remains or impressions of living organisms that lived in the past. They can be found in rocks or sediments and provide important information about the history of life on Earth.
Which type of fossils is found only rarely?
Maybe a T rex or some other kind of dinosaur
