∙ 13y agothey are about the same age. otherwise they would be different fossils.
Wiki User
∙ 12y agoWe may conclude that they were neighbors in both space and time.
Wiki User
∙ 10y agoIt means that the two organisms probably lived around the same time period.

Are Fossils used to correlate sedimentary rocks that are widely separated by using the rocks distinctive fossil content and applying the principle of fossil succession?
no
What is the tissue type that has fibers widely separated?
nervous tisue
What are hydrocarbons and what are they widely used for?
Hydrocarbons are natural or artificial compounds that contain hydrogen-carbon bonds that can release energy when oxidized (mainly burned). Fossil fuels are organic hydrocarbons and are widely used to generate energy. Simpler inorganic hydrocarbons such as methane and ethane exist in substantial quantities on other planets and moons.
How did the opponents of the continental drift hypothesis account for the existence of similar life forms on widely separated land-masses?
Migration across land bridges.
How is graphite different from other allotrope's of carbon?
The carbon atoms in graphite are arranged in widely spaced layers.
Which characteristics of a fossil would you make it useful as an index fossil in determining the relative age of widely separated rock layers?
C). a narrow time range and a wide geographic range

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.
