Fossils

the bone structure is important.. it is relative to the bone structures in other animals such as humans, fish, tigers ,etc.

the study of the past life me is the key to the futrue

Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.

No one invented fossils. That would be like asking who invented water. Fossils are a natural occurrence that happens over a long time. Aristotle had questions as early as 4 BC of why seashells were found on mountaintops. See the related link for more information.

A True form fossil is a fossil of the whole/entire body of the organism.

Fossils are essentially plant and animal matter that have been replaced with stone over time, leaving a solid stone that appears like the original plant or animal matter.

Fossilized leaves, petrified wood, and small oceanic creatures are common.

Fossilized bone is the most common animal remains with most other parts of the animal carcass decaying very quickly. But, they are somewhat rarer than the leaves & small marine animals.

Keep in mind that multi-million year old fossils are extremely fragile and should only be handled by experts.

Fossils can often be dated by determining the age of the soils surrounding them.

Many species of animals have come and vanished on earth over the centuries and millenia. And the animal species, including man, that have survived, have changed over time.

The fossils provide a record of the species that have existed in the past, as well as providing additional support for Darwin's theory of evolution by demonstrating changes to various species over time.

A few species including Mammoths have been found locked in ice and have been preserved virtually intact for thousands of years as frozen specimens, finds that can be extremely exciting.

The Piltdown man

It creats a cast fossil. This question isn't very tricky to figure out. A fossil is formed when something dies. If buried, it won't take as long for the fossil to be formed. But you won't be alive to see the fossil. It's takes about 1000 years for the fossil to become complete, depending on how much sedimentary rock is around that specific area. But, what about something that's not buried? Well, as you know dinosaurs roamed the earth millions of years ago. As time passed, and they died, the tectonic plates holding the continents of the earth would crash together, forming mountians, and sometimes creating a trench where water slowly grew until it was a pond, river, lake, or ocean. As the water grew, it eventually coverd the carcas of the dinosaur. Once underwater, the soft sand covered the body of the dinoaur. Then, as the river dried, the skeletal structer had grown into the sand and was now hardening as the sun dried the dirt. Once the bones of the dinosaur was wrapped around by sedimentay rock, it was preserved creating fossils in the rock. How scientists get these fossils out of the rock? They have to brush every grain of sand from around the bones, and the put the whole structure together, creating the skeleton and then showing it in museums.

no it is impossible to get both fossils in mt.moon sorry =(

Propane is called a fossil fuel because it was formed millions of years ago from the remains of tiny sea animals and plants.

Propane is one of the many fuels that are included in the liquefied petroleum (or LP-gas) family. In the United States, propane and LP-gas often mean the same thing, because propane is the most common type of LP gas used. Just as water can be a liquid or a gas (steam), so can propane. Under normal conditions, propane is a gas. Under pressure, propane becomes a liquid.

Probably a trace fossil; evidences of an organisms existence, without the body. Trace fossils include footprints, feces, burrow marks, and chemical signatures.

Punctuated equilibrium is a model of a rapid mutation that happens rapidly or over a short period of time. On the other hand the gradualism model states that this change takes place slowly unlike the punctuated equilibrium.

They think it has too many gaps in it to explain anything, even though biologist have proven many, many things with fossils.

1. When that animal/plant lived.

2.What killed that animal/plant.

Indirect evidence from Seismic Waves, and direct evidence from rock samples.

when an organism dies, its soft parts often decay quickly or are eaten by animals. that is why only hard parts of an organism generally leave fossils. these hard parts include bones, shells, teeth, seeds, and woody stems.

relative dating

it happens when dead mammals begin to pile on top of each other after a while then they get compressed or buried under rock and turn into a fossil. It could also fall into a tar pit or marshes locking all of it underneath the earth and the bones turn into rock via a chemical reaction.

To become a rock, mud must first undergo the process of lithification. This would involve the subsequent covering of the mud with additional sediments. If the weight of those sediments becomes great enough, the pressure will squeeze out the air and water from between the small clay and silt particles that the mud is composed of. Eventually, minerals will precipitate out of the remaining water, crystallizing to form a cement that holds the clay and silt particles together as a new sedimentary rock.

Fossilisation is a rather rare occurrence. Organisms must 'fall' into conditions where decay does not occur. The soft tissues of organisms usually do not form fossils. Fossilisation is more likely in seas, lakes, swamps and caves, but unlikely on land. Geological processes, and human activity, are constantly moving and destroying the sedimentary rocks which contain fossils.

* The skin type, the thickness of the skin and the color. * Stupid or smart animal.... * how tall it will be when it grows up..if its a baby, ....... sorta.... O.o * male or female....well kinda....depends * pregante or not

There are many types of rocks that are found in Washington state. The most common ones found are sedimentary rocks and metamorphic rocks.

Actually, the only assumption made is the assumption that the world was not created purposefully with the intention of deceiving scientists into thinking common descent is true.

Molds and casts are a third method of fossil preservation. Molds form after hard parts have been buried in mud, clay, or other material that turns to stone. Later, water dissolves the buried hard part, leaving only an impression or mold of the original. When this mold is filled with new material, a cast of the original is formed.
