Index fossil a fossil that is found in rocks of only one particular time period. a species of ancient extinct elephants. archaeology. the scientific study of artifacts toward an understanding of the lives and cultures of past peoples. artifacts. objects made or modified by a human culture and often late recovered by some archaeological endeavor. Fossil An actual remaining part or mark that shows evidence of an organism that lived in the distant past. The orderly collection of all known fossils that have existed throughout life's history. Most ethanol is made from non fossil fuels, but it is a popular misconception to consider it a non-fossil fuel unless it is clearly from a biologic source. Bio diesel is by definition made from biological sources and therefore is not a fossil fuel. It is a used as a replacement for petrochemical diesel which is an oil distillate.
An index fossil is organisms that is a signature for certain geographical eras. Index fossils are a charting of time that is used to describe other organisms found in that time era. The fossils were found in the stones that are determinations by carbon indexing and therefore are index fossils.

The fossils were found in the stones that are determinations by carbon indexing and therefore are index fossils. Organic matter (dead plants and animals) were compressed and heated to form fossil fuels. Fossil fuels were formed when Earth formed. {apex} Organic matter was compressed and heated. Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.

The fossils were found in the stones that are determinations by carbon indexing and therefore are index fossils. index fossil [ ĭn ′ dĕks′ ] The fossil remains of an organism that lived in a particular geologic age, used to identify or date the rock or rock layer in which it is found. A type of trilobite is used as an index fossil these fossils were made about 540 million years ago a scientist finds a trilobite fossils in layer 5 apex. Answer. B. Fossils in layer 5 are less than 540 million years old.

Eggs are laid at two distinct times of the year: early in spring when the o. ak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata.” Index fossils are used to "index" a certain period of time, to date it.

Fossils in layer 5 are less than 540 million years old. Fossil occurrence. In the Netherlands known from interglacial deposits with a Tiglian and Pretiglian age. In the United Kingdom only present in the late Tiglian. As an index fossil. Viviparus glacialis is, although already present in the Pretiglian, considered as a guide fossil or index fossil for the Tiglian.

Ancient Life: Apex Chert Microfossils This slide shows pictures of some of the oldest known fossils from Earth, bacteria fossils from the Apex Chert in Western Australia. Approximately 3.5 billion years ago, this rock was sediment on the floor of an ancient lake or ocean. Index Fossil. a fossil known to have lived in a particular geologic age that can be used to date the rock layer in which it is found. Order of Rock Layers. A way in which scientists can find the relative age of a fossil and can only be used when rock layers are preserved in their original sequence. Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
