Fossils

Fossilised ancient life-forms. There are even fossilsed bacteria from 30 billion years ago.

The sum of all the fossils that exist is called that fossil record. It includes fossils from all geologic time periods.

Fossils are formed from millions of years ago when sometime during the extinction of the dinosaurs, their skeletons get caught in rocks during Earth's process of Erosion. Fossils of other prehistoric creatures, like the Sea Monsters, were fossilized earlier before and/or after the K-1 Event.

First of all, evolution is a FACT not a theory. You must be referring to Charles Darwin's theory of evolution by means of natural selection. There is no denying the fact that evolution happens, scientists just didn't know exactly how it worked until Darwin suggested one plausible scientific explanation which he called natural selection. Natural selection is simply the change in allele frequencies of an organism which results that organism becoming either better or worse suited to survive in its environment. Being better suited to survive means that the organism is more likely to pass on the beneficial genetic trait to it's offspring.

Rather than asking for evidence which helps prove evolution, try looking for verifiable scientific evidence which disproves it. After all, science is not about making claims and looking for evidence to prove them, but rather generating hypothesis and looking for ways to disprove them.

When an organism is buried it is usually in sedementary rock, which is sof and layered. Over time the layers of sedements compact and can soak into the bones of an organism. As the bones are put under extreme pressure the become more like rocks and are thus presserved.

Scientists can learn from a fossil of animal by its age, diet, and physical characteristics, depending on the condition of the fossil. For example, scientists would not be able to tell of a hominid was a new species or not if a few bones were missing, because of the fact that they could determine different or similar traits than other species of hominid.

Paleontology is the study of fossils, therefore a paleontologist is a person who studies fossils.

Petrification occurs when body parts of the organism are replaced by minerals dissolved in ground water. For example, a buried tree may have its wood replaced over millions of years by silica that is dissolved in the surrounding ground water.

As long as the online class teaches the rules of your state, then an online class would be helpful. If it's just basic information, it could be a waste of time. Be sure you practice driving with your child.

In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.

Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the "jigsaw puzzles" of biostratigraphy.Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.

It tells you the Age, Place is was from and the Species of the Fossil

Fossil fuel + Oxygen gas > Carbon dioxide + water + heat (apex)

Scientists use a method called Carbon Dating to find out the age of a fossil.

1. An ancient animal dies and sinks to the bottom of a river

2. Layers of sediments cover the animal's body

3.Over millions of years, the sediment harden to become rock. The animal is preserved as a fossil.

4. The rock erodes. The fossil is exposed on the surface of a rock.

Dragons are mythical creatures that do not actually exist in reality, so scientists have not found any remains of them. The stories of dragons are part of folklore and mythology, not based on actual evidence or scientific findings.

index fossils are used to date the rock layers they are found incc

Both copy the shape of its ancient organisms.a MOLD is a hollow area in sediment in the shape of an organism or part of an organism.a mold forms when the hars part of the organism,such as a shell,is buried in sediment.Later, water carrys dissolved minerals and sediment there,the result is a cast.

A CAST is a solid copy of the shapes of organisms.a cats is the opposite of a mold.both mold and cast preserved details of the animals structure

The La Brea Tar Pits (or Rancho La Brea Tar Pits) are a cluster of tar pits around which Hancock Park was formed, in the urban heart of Los Angeles. Asphaltum or tar (brea in Spanish) has seeped up from the ground in this area for tens of thousands of years. The tar is often covered with water. Over many centuries, animals that came to drink the water fell in, sank in the tar, and were preserved as bones. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. The La Brea Tar Pits are now a registered National Natural Landmark.

Mammals actually first came into existence about 220 million years ago, which is about 155 million years before the dinosaurs went extinct, and only about 10 million years after they themselves first evolved. So mammals actually lived alongside the dinosaurs, though played a much smaller role.

no. 50,000 years is the upper limit for using it for dating.

Fossils are Animal bones that were preserved for a long period of time.

What you are thinking about is artifacts.

Schists are formed when a sedimentary rock is deformed by great heat and pressure, deep within the Earth's crust. This deformation means that fossils do not survive in schists. Only less deformed rocks, such as slate and shale, can hold fossils.
