Fossils

Fossils belong to the kingdom Animalia, which includes all animals both living and extinct. Fossils are the preserved remains or traces of organisms that lived in the past.

A fossil bed or fossil site contains many different types of fossils. These can include remains of plants, animals, and other organisms that have been preserved in sedimentary rocks over millions of years.

The trilobite species Eldredgeops rana is a common New York State index fossil found in Devonian rock layers. If a rock layer containing this index fossil is missing due to unconformity, it suggests a gap in the rock record where deposition ceased, erosion occurred, and then new sediment layers were deposited on top.

Almost all monotreme fossils have been found in Australia. An exception is the fossil of a platypus-like creature named Monotrematus sudamericanum found in Argentina, within a Patagonian rock formation.

Fossils of index fossils, which are species that lived for short periods and were widespread geographically, are commonly used in stratigraphy to date and correlate rock layers. These species are useful markers because they can be found in multiple locations and help determine the age of the rock layers they are found in.

Yes, fossils have been found in Death Valley. Remains of ancient marine life, such as seashells and marine reptiles, have been discovered in the region, indicating that the area was once covered by a seabed millions of years ago. Additionally, fossil footprints of early mammals have been uncovered in some parts of Death Valley.

Yes, a fossil purse with a 1954 lining could be considered an authentic vintage item if it was produced by Fossil around that time period. It's important to authenticate the item through research on Fossil's history and product lines from that era to confirm its authenticity.

1) Fossils are imprints of plants or animals from the past

2) Fossils are mainly found in metamorphic rock formations

3) Index fossils are fossils that are found everywhere, but only lived a short period of time. The most common is the trilobite

Some animal groups with a good fossil record showing their evolutionary development include dinosaurs, mammals, and marine invertebrates like trilobites. Fossil evidence of these groups has allowed scientists to trace their evolutionary history and understand how they diversified and adapted over time.

Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.

Sedimentary rocks (such as shale, sandstone, and limestone) are the best types of rock for fossil formation. These rocks are formed from layers of sediment that can preserve and protect fossils over time. Additionally, the fine-grained nature of sedimentary rocks allows for the detailed preservation of fossils.

Soft animal parts can become fossilized through a process called carbonization, where organic material is compressed and heated under sediment, leaving a carbon residue. This can preserve delicate structures like feathers or skin. Another way is through replacement, where minerals gradually replace the organic material, preserving the shape and detail of the soft tissue.

When plants die on land, they can form peat, which can then transform into coal over millions of years due to heat and pressure. Coal is a fossil fuel that is commonly formed from the remains of terrestrial plants.

Fossils of the knee joint and pelvis of Australopithecus anamensis and Australopithecus afarensis show adaptations for bipedal locomotion, such as a valgus knee angle and a broader, shorter pelvis. Also, the position of the foramen magnum at the base of the skull suggests an upright posture. Lastly, footprints in volcanic ash at Laetoli in Tanzania show bipedal walking by Australopithecus afarensis.

Well, by using a method known as carbon dating, archaelogists are able to trace an artifact back to get an estimate on how old ity is. For example, archaelogist recently found 11000 year old fishing equipment in California. With this information, you can conclude that human life has been in the Americas for at least 11000 years, logically, you can assume, knowing that human kind migrated over the once frozen bering staight between russia and alaska, you know that they didn't have any transportation except for walking. Then they had to somehow get to the California shore, settle down and invent the fishing equipment adaquet for the waters of California. So you can probably confirm with those facts that human kind has been in America for at least 1100-12000 years and most people believe it has been longer. You can apply this knowledge to fossils of animals and plants too, and ponder the effects that said animal would have had on nature.

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.
