Fossils
This category is for questions about the bones, fragments, imprints, and other remainders from a different time. The questions and answer you will find here are history set in stone -- our past, immortalized in solid rock. You will also be able to find questions pertaining to the locations of these fossils, how you might identify them, and how they were formed.

Did Everything that died long ago become fossils?
Lots of things did but not EVERYTHING lots of the smaller things Became oil and coal It was mostly big things that became Fossills. Lots of things did but not EVERYTHING lots of the smaller things Became oil and coal It was mostly big things that became Fossills.
When did trilobites first appear in fossil record?
The first trilobites appear about the same time in Siberian, Moroccan and North American strata of about 524 million years of age, at the start of series 2 of the Cambrian Period. The first trilobites include fallotaspidoids Profallotaspis, Eofallotaspis, and Fritzaspis, but also include an ellipsocephaloid, Hupetina. For the role of trilobites in biostratigraphy, see this page: http://www.trilobites.info/biostratigraphy.htm
If you find a fossil of a furn in an iceberg what would this tell you about the region?
A fossil of a fern in an area would indicate that at one time, the region had a temperate to tropical climate. Ferns cannot grow if the climate is too cold, though they can grow in cool climates and moderate elevations.
What are fossil fuels used for?
Fossil fuels are used to generate electricity in our homes and for to power our automobiles and other vehicles and power tools.
No, fossil fuels (coal, oil and natural gas) can only be used once. For this reason they are called non-renewable sources of energy.

What does relative dating provide for the age of a rock layer or fossil?
Relative dating provides an estimated age of a rock layer or fossil based on its position in relation to other rock layers or fossils. It helps determine the sequence of events in Earth's history, but does not provide an exact numerical age.
The area was probably a wet area like a lake or an ocean that dried out some time after the fish died. (you should know this stuff!!)
Scientists have found australopithecine fossils in?
Neanderthals never lived in Africa. They only lived in Europe, the Middle East, and Asia.
- The Adirondack rocks have been both severely folded and sheared by ductile deformation and shattered by brittle.
Are trilobites warm or cold blooded?
Trilobites were warm blooded creatures that lived in the ocean from the cambrian period all the way until they were wiped out in in the permian period.
Darwin realized after seeing a bunch of fossils (and the differences between the finches on the Galapagos Islands) that animals must be adapting to better fit their environments, and thus, becoming more diverse.
If a leaf is fossilized it would most likely form what type of fossil?
Probably, carbonateous fossil.
What link do seed ferns represent in fossil record?
The first fossil records of vascular plants that is land plants with vascular tissues Fossil ferns and seed ferns include Pecopteris Cyclopteris
What are three requirements for a fossil to be an index fossil?
Index fossils
Fossils of organisms that lived during a relatively short geologic time span.
The three conditions
To be an index fossil, a fossil organism must be found throughout the world. It must be easy to identify and many fossils of that organism must exist.

Cyanobacteria fossils are the oldest known fossils on Earth. Stromatolites found near Shark Bay, Western Australia, which are made by cyanobacteria, have been dated back to 3.5 billion years in the Paleoarchean Era . They survive to modern day. Identical stromatolites are being formed not 15 miles from there 3.5 billion year old fossilised ancestors.
Icthyosaurs on the other had appeared in the fossil record about 245 million years ago in the Middle Triassic Epoch. They died out about 90 million years ago in the Upper Cretaceous Epoch, about 25 million years before the KT extinction that saw the deaths of the other great marine reptiles the mosasaurs and the pleisoasurs as well as all non avian dinosaurs.
Fossilized evidence of Earth's first forms of life would consist of?
The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago.
To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.
Is stratigraphic dating accurate for dating fossils?
Carbon dating and radioactive dating are more effective, assuming those arn't the same thing. =]

The three major categories of evidence provided by the fossil record are?
The three major categories of evidence provided by the fossil record are body fossils (actual remains of organisms), trace fossils (impressions or structures left by past organisms), and chemical fossils (organic molecules preserved in rocks). These categories help scientists understand past life forms, their environments, and evolution over time.
The way fossils are formed in very dry places is called what?
Fossils can be formed by:
- Mummification
- Petrification
- Desiccation

Fossils are the remains of plants and animals that lived long ago?
I think your looking for Fossils, They contain imprints of Plant and Animal material up to millions of years old.
If you want a specific rock that contains Preserved animal or plant remains, try Amber, its Tree sap that has solidified into rock over time and often the insects or plants are perfectly preserved inside.
I hope this was helpfull!
