  Fossil record - Wikipedia, the free encyclopedia
These are called fossils, and the totality of these objects and their placement in rock formations is referred to as the fossil record.
The fossil record is one of the primary sources of data relevant to the study of evolution.
The fossil record and faunal succession form the basis of the science of biostratigraphy or determining the age of rocks based on the fossils they contain.

 Fossil - Wikipedia, the free encyclopedia
The totality of fossils and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.
However, fossils may also consist of the marks left behind by the organism while it was alive, such as the footprint or feces of a dinosaur or reptile.
This can be a species known only from fossils until living representatives were discovered, such as the coelacanth and the ginkgo tree, or a single living species with no close relatives, such as the horseshoe crab, that is the sole survivor of a once large and widespread group in the fossil record.

 Examining the Fossil Record
A fossil is the hardened remains of a plant or animal, preserved in rock.
When a fossil appears in the record, it appears full-grown, so to speak, as developed as it is going to get, and that type of fossil stays pretty much the same either down to the present time (for creatures that are still alive) or until it disappears from the fossil record.
Darwin and TH Huxley argued that the fossil record was incomplete, and that intermediate forms would eventually be found to support the theory of evolution.

 The Record of Time:  Introduction
Some of the best preserved fossils were deep frozen in permafrost soil or ice, dehydrated in dry desert caves, or encased in tree resin that hardened into amber.
There is bias in the fossil record resulting from the fact that paleontologists have not equally searched all areas of the globe.
For long periods of time, most individuals in some species may not have survived long enough after their deaths to become fossils because they were eaten, and the few fossils that were formed may have been destroyed at a high rate by increased erosion in particular regions.

 Resource of the American Scientific Affiliation: Taxonomy, Transitional Forms, and the Fossil Record by Keith B. Miller
Even within well-preserved fossil series it is usually difficult to distinguish the record of speciation occurring within a particular depositional basin (or environment) from the effects of immigration of new species from outside that basin.
When the fossil record is included, the boundaries between higher taxa become blurred during the major morphological radiations associated with the appearance of new higher taxa.
As a result, for lineages with a good fossil record, the appearance of a new higher taxon is associated with the occurrence of species whose taxonomic identities are uncertain or whose morphologies converge closely on that of the new higher taxon.

 Fossil Record
Fossils are traces of organisms that lived in the past.
The absolute age of the fossil can be determined though radiometric dating and determining the layer of rock in which the fossil was found.
In each fossil column, you may have 3 specimens, one from the main time period, one from the upper and one from the lower.

Within the past few decades, population genetics and studies in the fossil record have lead to the rise of punctuated equilibria over phyletic gradualism as the dominant mode of evolution.
While the general nature of the fossil record is a good evidence for evolution, it tends to exclude certain forms of creationism (particularly essentialist ones).

 The fossil record   (Site not responding. Last check: 2007-10-07)
Fossils of the mammal-like reptile, Lystrosaurus, are so common, notably in South Africa, that it is said that paleontologists don’t even bother to pick up specimens when they see them at their feet.
Whenever a fossil is listed as having a long stratigraphic range (say, Cambrian to Devonian), this range may conceal a contradictory stratigraphic occurrence of the fossil from one part of the world to another.
These include marine fossils, for which a poor fossil record cannot be used as an excuse for their appearance beyond the ‘proper’ stratigraphic intervals.

Heathcote said that there have been many attempts to analyze evolutionary patterns using the fossil record, but that the patterns can only be interpreted usefully in the context of stratigraphy — essentially how old the fossils are.
It's important to know the quality of the fossil record to better assess whether an apparently large number of genera at any one time - say, the late Jurassic period - is due to genuine species diversity or just exceptionally good preservation.

The overall fossil record reveals that even when we use the evolutionists dates (which are incorrect) and arrange the fossil according to these dates that no human evolution has taken place.
The total fossil picture is not shown in these types of "family trees." If the total fossil record is used a drawing of a family tree is not possible because the fossil do not fit the evolutionary scenario.

Fossil sites within the localities were also used as this better represents the wealth of material from different regions.
Of extreme importance when considering human fossils is the notion of man’s place in nature and the understanding of evolutionary processes by the ‘culture’ that discovers and describes these fossils.
We think it follows then that the recovery of fossils in Europe and their interpretation as having to do with man’s ancestry were contingent upon the paradigms set in place by the Age of Enlightenment.

 CC200: Transitional fossils
What a transitional fossil is, in keeping with what the theory of evolution predicts, is a fossil that shows a mosaic of features from an older and more recent organism.
There are many fossils of human ancestors, and the differences between species are so gradual that it is not always clear where to draw the lines between them.
Fossils of the diatom Rhizosolenia are very common (they are mined as diatomaceous earth), and they show a continuous record of almost two million years which includes a record of a speciation event (Miller 1999, 44-45).

 Fossil Record Overview - Missing Transitional Forms
A severe problem for evolutionists is the absence of transitional forms in the fossil record.
By transitional forms, we mean intermediate forms of life appearing in the fossil record that are "in-between" existing types of organisms found today or in the past.
When fossils are examined they form records of existing and extinct organisms with clearly defined gaps, or missing transitional forms, consistent with a creationist's view of origins.

Much of this vast database is observational, and the evidence came to light with the study of fossils (paleontology) and the rock record (geology).
The fossil record remains first and foremost among the databases that document changes in past life on Earth.
With the passing of time, the layers of sediments are compacted by the weight of overlying sediments and cemented together to become the sedimentary rocks called limestone, shale, sandstone, and conglomerate.

Although scientists will continue to discover new varieties of fossil animals and plants, it is generally agreed that the millions of fossils already discovered (and the sediments already explored) provide a reliable indication of which way the evidence is going.
In almost all cases, the very existence of the fossils, in the types and numbers discovered, strongly indicates catastrophic conditions were involved in their burial and preservation.

 New study affirms reliability of fossil record
The quality of the fossil record has passed a critical test, as indicated by a study of bivalves conducted by Susan Kidwell, Professor in Geophysical Sciences at the University of Chicago.
The fossil record may not be perfect, but it passed a critical test with flying colors, according to a study by University of Chicago paleontologist Susan M. Kidwell that will be published in the Feb. 11 issue of the journal Science.
Her study ruled out longstanding predictions that patterns in the fossil record would be dictated by differences in shell toughness among evolutionary lineages.

The point emerges that if we examine the fossil record in detail, whether at the level of orders or of species, we find–over and over again–not gradual evolution, but the sudden explosion of one group at the expense of another.
When terrestrial strata and the fossil record are examined, it is to be seen that all living organisms appeared simultaneously.
As may be seen, the fossil record indicates that living things did not evolve from primitive to the advanced forms, but instead emerged all of a sudden and in a perfect state.

Fossils of the same species were found on several different continents.
Wegener proposed that the species dispersed when the continents were connected and later carried to their present positions as the continents drifted.
The distribution of other species can also be accounted for by initially spreading across Pangaea, followed by the breakup of the supercontinent, and movement of the continents to their present positions.
