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.

Is it true or False that Fossil Fuels are liquid deposits of iron ore found only in sedimentary rock formations?

FALSE.

Fossil fuels come from organic matter that has undergone anaerobic decomposition.

We suspect that much of our fossil fuel comes from buried plankton and dinosaurs.

What is one reason why the fossil record is incomplete?

The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.

What best describes fossil?

Fossils (from Latin fossus, literally "having been dug up") are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.

Fossil are bones of extinct creatures that are said to live thousands of years ago.

A fossil is the ancient remains of animals, plants and other organisms from the distant past. The word is from a Latin word 'fossus' which means 'dug up'.

Darwin found fossils of many different organisms that were different from any living species How would this finding have affected his understanding of life's diversity?

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.

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.

The hominid fossil has the same number of bones in its hand as a gorilla. what type of evidence for evolution does this represent?

That evidence is homologous. Shared common ancestry. In this case you could trace this homology back as far as the common ancestor of gorillas and hominid fossils, or as far back as the emergence of all tetrapods.

12 periods in order from the preCambrian to the quaternary?

The 11 geological periods from Precambrian to Quaternary are :-

  • Paleozoic Era
    • Cambrian Period - 542 to 488.3 million years ago
    • Ordovician Period - 488.3 to 443.7 Ma
    • Silurian Period - 443.7 to 416 Ma
    • Devonian Period - 416 to 359.2 Ma
    • Carboniferous Period - 359.2 to 299 Ma
    • Permian Period - 299 to 251 Ma
  • Mesozoic Era
    • Triassic Period - 251 to 199.6 Ma
    • Jurassic Period - 199.6 to 145.5 Ma
    • Cretaceous Period - 145.5 to 65.5 Ma
  • Cenozoic Era
    • Paleogene Period - 65.5 to 23.3 Ma
    • Neogene Period - 23.3 to 2.588 Ma

Scientists have found australopithecine fossils in?

Neanderthals never lived in Africa. They only lived in Europe, the Middle East, and Asia.

What kind of things can be fossilized?

A fossil is the remains, trace or indication of life in the past. So any organism, plant or animal that has a mineral or organic or inorganic matter that is not oxidized before burial can be fossilized along with traces like worm trails or dinosaur footprints, impressions of leaves or rarely of jellyfish. The most common fossils are minerals: shells and bone(calcium carbonate) or silicon dioxide (opal) along with the lignin of plants

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.

Younger fossils and not older fossils are more like?

this is an incoherent question that cannot possibly be answered

What type of rock must the rock layer be if it contains clam fossils?


It would necessarily be sedimentary rock, formed in a saltwater or freshwater environment, depending on the type of clam.

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.

Why do paleontologists often look for fossils along the sides of hills?

they search along side hills because that is where the most fossils can be found. when the animals migrated across the land many weren't able to make it all the way up the hill so the ended up falling get stuck in the mud and dying. also they could have gotten stuck in a mud slide or sink hole.

i hpoe this answers your question!

What parts of plants are most often preserved as fossils?

They are leaves stems roots and seeds I checked its in my book(:

What is a half-life and how is it used to determine the absolute age of a rock?

Half-Life is the time it takes for one half of the amount of an element to decay. This process is inverse exponential, i.e. in one half-life there will be one half of the element left, in two there will be one quarter, in three there will be one eighth, and so on.

If you know how much material was initially present, you can measure how much is present now, and you can calculate how long that took.

Often, we use Carbon-14 dating, which compares the ratio of Carbon-14 to Carbon-12. When plants and animals are alive, they affix Carbon-14 into their celluar structures, causing a higher concentration as compared to regular rocks/soils in a regular way based on the amount of Carbon-14 in the general environment. Since we know the original ratio at the point of death, we can date the fossil.

The half-life of carbon is 5730 years after that, half of the remaining carbon - 14 decays.
they uses carbon14 to compare the age of rocks
