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.
Is a fossilized bee hive common?
no - not common. corals are often mistaken for beehives. Check out "favosites."
Do fossils define earths history?
yes. It gives vital clues to uncover the events that once occurred on earth.
# It was sedimentary rock. # They were below the tree line. # The rock layer was exposed. # They were able to recognize tropical plants of ancient origin. # The fossils were once live plants at a time in which a tropical climate existed. # The climate is different now than it was at the time the fossil plants were alive. # The area where the fossils were found was once closer to the equator than it is now.
By comparing fossils of a species from long ago to those of today you can conclude that?
today's species evolved from those of the past.
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
Where were fossils of carnotaurus sastrel recently found?
As I konow they lived in Patagonia, Argentina, so probbably fossils were found there.
the answer is cooled magma
Ediacaran fauna are the fossil animals found in rocks dated around 650-540 million years ago, just before the Cambrian period.
What conditions were needed to turn the plants and animals into fossils?
near immediate plastering by mud and afterwards a period of drought and even then, many fossils are destroyed by nature and are generally very fragile
Why are fossils important to scientist?
it gives information about the past which to scientists is important to know
What does the fossil record gourmet say is needed to make a fossil?
A living thing.
Look at the Bill Nye Fossils video for more
How carbon imprint fossils made?
gago kau at ang bumassa n2 no kaya uwi na dun g@g0 kac walang mahahanap d2 kaya uwi kana walng ya mong nanay
A fossil of a plant, insect, animal - carbonized; the meaning of carbonized is reduced only to a carbon footprint.
What led hooke to argue that fossils had once been living organisms?
hooke published his conclusion that fossils are remains of plants and animals .
Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
decent with modification
Why are there few fossils from the precambrian era?
Actually, it isn't really true! We now know (unlike Darwin who would have rejoiced to know what we now know!) that fossils in the PreCambrian are numerous and spread world-wide. But many are very small and not easily recognised or exist in specialised geologically circumstance, often preserved in relatively little-known places. Much PreCambrian rock is igneous, products of vulcanism, and obviously do not preserve fossils. But where suitable conditions prevailed, unusual fossils can be found are a the subject of a great deal of study. Many of the best preserved are where fine volcanic ash settled over the ancient seabed preserving the soft-bodied forms which were around 500-600ma ago.
Precambrian fossils may be found at several localities in UK (notably Charnwood Forest in Leicestershire), in Canada, Namibia, Russia, China and especially in Australia.
What are the 5 types of fossil?
the 5 types of fossils are:
1.petrified fossil
2.carbon films
3.trace fossil
4.perserved remains
5.mold and cast
The lack of Precambrian index fossils is the primary reason that?
correlation between rock units is impossible
eroding hillsides
How are rock layers used to determine the relative ages of fossils?
The Principle of Superposition argues that rock layers towards the top are younger than those at the bottom. This was the principal technique used in the early days.
Fossils have discontinuities - a group will appear, and after a time will vanish again. But very similar fossils appear around the world at the same time.
This subject paleontology, has good records, and a newly found fossil can usually be identified by comparison with the paleontological record.
Today of course, radiometric dating is used very widely to determine the age of both rocks themselves, and of fossils. These techniques use the half-life of radioactive elements to determine the age.
