Fossils

Perhaps, as we will likely be on earth a relatively short time, we are abundant and are wide spread geographically.

Most invertebrates do not fossilize because of the lack of bones or exoskeleton. Soft tissue rarely fossilizes.

B for PLATO users

Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.

chemical information is often desirable and can be supplied by means of the correlation

index (CI).

The correlation index, developed by the US Bureau of Mines, is based on the

plot of specific gravity versus the reciprocal of the boiling point in degrees Kelvin

(K = 0C + 273). For pure hydrocarbons, the line described by the constants of

the individual members of the normal paraffin series is given a value of CI = 0

and a parallel line passing through the point for the values of benzene is given as

CI = 100 (Fig. 3.5); thus,

CI = 473.7J - 456.8 + 48, 640/K

where K for a petroleum fraction is the average boiling point determined by the

standard Bureau of Mines distillation method and d is the specific gravity (Gruse

and Stevens, 1960).

Yes

Oldest fossils have been found in many areas of the Great Persian Empire. This was in ancient history, when Cyrus The Great ruled Persia. At the time of his rule many archaeologists found fossils dating back to 1 billion years ago from creatures never thought of by any human. Persia is modern day Iran, and is going through many revolutions, however if you ever decide to go there, there is a Museum called, "Kootlet", it contains many of the most ancient fossils ever discovered by man kind!

Hope this helps,

i have no idea people search on the internet i mean comon dont be lazy just search for it (derf) your very welcome...........please improve :-D

The Mudstone was packed so tightly around the fish that moisture, warmth and oxygen could not reach it and begin the process of decay. This is why most fossalised fish found in Mudstone are still intact with skin and bone!

The Trilobite.

False

Uranium dating methods were not used for fossils dating.

550 million years old

Shale is made from layers of mud and clay pressed together. :)

because they change slowly through time

Index fossils are very important to geologists because they identify geological time periods.

Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.

Iridium is a very rare element in Earth's crust, however rocks that have an age equal to that of the K-T boundary are significantly enriched in iridium. It is theorised that this enrichment is due to the impact of an asteroid with Earth (as asteroids are rich in iridium and the resultant massive explosion spread iridium enriched debris all over the world). This asteroid impact is thought to have been a significant event in the mass extinction even that wiped out the dinosaurs.

This is known as the Alverez hypothesis. For more information, please see the related link.

covered up quickly, also important depending on the type of fossilization, water running through the area. Key would be the mineral replacement offered to the fossil.

Amber and petrified wood are both formed from organic material, with amber being fossilized tree resin and petrified wood being fossilized wood. Both can contain preserved organisms and have a similar appearance due to their fossilization process. They are valued for their beauty and used in jewelry and decorative items.

Bleach

Yes, It was discovered near Earnscliffe, PEI along the beach about 2010, by our aunt. We have some from their.

amber and ice

well you have to dig in a place that you might fossils and you start diging up and you start seeing bones

The bedrock in Syracuse, New York, belongs to the Marcellus Formation, which is a Devonian-aged formation, approximately 390-370 million years old.
