Fossils

Trace fossils are things like foot prints, burrows, and fossilized feces (coprolites). So quite simply, they're formed by the living-part of an animal's life (rather than its death, being buried as a body fossil). If there's a muddy bottom and an animal crawls across it, it could leave an imprint. Burrows could left behind. These divots and so on can get filled in with hardy sediment that becomes fossilized when the mud is covered over and the sediments become a standard sedimentary rock containing trace fossils.

Note; it only works for sedimentary rocks ... but if you know approximately how long ago that type of animal lived, then you know about when the rock began to form around it (to form the fossil).

3 and a half years.

Weathering and erosion break down rocks into smaller pieces called sediments. This process can happen through physical weathering (mechanical breakdown) or chemical weathering (decomposition of minerals). The resulting sediments can then be transported by wind, water, or ice to new locations.

Relatively short rime span. To be an index fossil, a fossil organism must be easy to identify and many fossils of that organism must exist.

Fossils are not found in extrusions and intrusions, such as lava flows and igneous rock formations, because the extreme heat and pressure generated during these volcanic processes usually destroy any organic material present. Fossils are typically found in sedimentary rocks, where the remains of organisms are buried and preserved in layers of sediment over time.

No. Think about it. Why do archaeologists usually have to dig down to find the remains of ancient civilizations? The same is true with sedimentary rock history.

Because we have quite a lot of evidence of prehistoric life and we just need to put together what we have and know like a jigsaw to make a clear picture.

However many pieces are still missing as fossilisation is quite rare and many species of life will not have been preserved. Pieces are also missing because we have not found all of the fossils on earth yet as we have not had the technology and time to yet.

The fossil record is also like a jigsaw in the way that one little piece of evidence can just put everything together and make things much more clear.

A fossil will most likely be found in a sedimentary rock because sedimentary rocks are made out of organic fragments such as rocks, shells, leaves, fossils, pebbles, and so on. A metamorphic rock would not hold a fossil because a metamorphic rock forms under great heat and pressure, and fossils would be destroyed under such conditions. An igneous rock would not hold a fossil because they form through the hardening of molten rock and fossils would be burned up and cremated in lava. Thus, fossils will most likely be found in a sedimentary rock.

The earliest fossils found in the horse family belong to an animal called Hyracotherium, also known as Eohippus. These fossils date back to the Eocene epoch, about 55 million years ago. Eohippus was a small, dog-sized animal with multiple toes on its feet, which is different from modern horses.

Yes, there is typically higher fossil diversity in warm, wet tropical regions because the conditions are favorable for the preservation of organic remains. The abundance of plant and animal life in these environments also increases the likelihood of fossilization.

Fossils can't usually provide information about the soft tissues of an organism because soft tissues rarely become fossilized. Also, fossils rarely provide information about interactions among organisms and thus tell us little about animal behavior.

There are many ways in which fossils can tell us about the changing surface of earth.

Fossils such as ammonites, jelly fish and fish have been found high in mountains. These species almost definitely were marine animals. If you assume that no "higher being" put them there to confuse us, then you have to conclude that the rock must have been at the bottom of the sea at some point and been pushed up to become the mountains.

You can also use distribution of fossils to tell how the continents have moved.

Examples of a small crocodile like creature named Mesosaurus have been found in Brazil and South America suggesting that during the Permian period (299 - 251 million years ago) they were connected. Another example is the mammal-like-reptile Lystrosaurus. Examples dating from about 250 million years ago were found in Antarctica, South Africa and India.

You cannot obtain the Cover Fossil if you already have the Plume Fossil in the same game without trading. In most games, you can only pick one of the fossils per playthrough. If you want both Pokémon, you'll need to trade with someone who chose differently.

Ammonites are considered body fossils because they are the preserved remains of an organism that lived millions of years ago. Trace fossils, on the other hand, are evidence of the activities of ancient organisms, such as footprints or burrows.

Mary Anning did her work along the Jurassic Coast in Lyme Regis, a town located in Dorset, England. She was a renowned fossil collector and paleontologist who made significant discoveries of Jurassic marine fossils in the cliffs and beaches of the area during the early 19th century.

The sedimentary rock formed from thin layers of compacted clay is called shale. Shale is characterized by its fissility, or ability to split into thin sheets, due to the alignment of clay particles during the rock's formation.

The majority of species whose fossils are found in rocks are extinct. These species lived in the past but no longer exist today. Fossilization occurs when the remains of organisms are preserved in sedimentary rock over millions of years.

the adaptations of species shown in the fossil record gives an idea to what their surrounding were like.
scientists study fossils to learn about climates long ago. If a plant fossil looks like a modern plant , sicentist guess two plants need the same climate.

No, a thin cavity in a rock showing where a shell has decayed is not considered a fossil. Fossils are the preserved remains or traces of ancient organisms, such as bones, shells, or imprints, that have been naturally preserved in rock or sediment over time. The empty space left behind by a decayed shell would be considered a mold or cast, not a fossil.

Yes, shell-shaped minerals can be found in rock cavities known as geodes. These geodes can form in sedimentary or volcanic rocks and can contain minerals such as quartz, calcite, or amethyst that have crystallized within the cavity. While not actual fossils, geodes are a type of mineral formation often found in rock cavities.

That's right; stromatolites are fossils of very old bacterial colonies.

Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by bio-films of microorganisms, especially cyanobacteria (commonly known as blue-green algae). Stromatolites are a major constituent of the fossil record for about the first 3.5 billion years of life on earth and were responsible for creating the atmosphere we breathe.

Futureistical :P we'll have flyin robots? o.o

Fossil records can help us understand past environments, evolution of species, extinction events, and the history of life on Earth. They can also provide insights into ancient ecosystems, behaviors of organisms, and the impact of environmental changes on life forms.

Mud is more likely than sand to fossilize an organism because mud has finer particles that can fill in cavities and preserve details of the organism's structure. In contrast, the looser nature of sand may not provide the same level of protection and support for fossilization.
