What are the remains of species that existed on Earth for relatively short periods of time were abundant and were wide-spread geographically?
The remains of species that existed for relatively short periods of time, were abundant, and widely distributed geographically are referred to as "index fossils." These fossils are valuable for dating and correlating the age of rock layers, as their presence indicates specific geological time frames. Common examples include trilobites and ammonites, which help geologists and paleontologists understand the chronological sequence of Earth's history.

Which are the remains of species that existed on earth for relatively short periods and were abundant and widespread geographically?
Fossils of index fossils, which are species that lived for short periods and were widespread geographically, are commonly used in stratigraphy to date and correlate rock layers. These species are useful markers because they can be found in multiple locations and help determine the age of the rock layers they are found in.
Is it true that To be a useful index fossil a species must have been rare?
No, an index fossil does not have to have been rare to be useful. The key characteristic of an index fossil is that it is easily recognizable, widespread geographically, and existed for a relatively short period of time. This allows geologists to use it to help date the rock layers in which it is found.
What Index fossils are the remains of species that were once abundant an?
Index fossils are the remains of species that were widespread, abundant, and existed for a relatively short geological time frame, making them valuable for dating and correlating the age of rock layers. These fossils serve as indicators of specific geological periods, allowing geologists and paleontologists to identify and correlate the ages of different sedimentary strata across various locations. Examples of well-known index fossils include Trilobites and Ammonites. Their presence in rock layers helps to establish a timeline of Earth's history.
Which fossil organisms could possibly be used as index (guide) fossils?
Index fossils are typically species that were widespread, abundant, and existed for a relatively short geological time period. Examples include trilobites, ammonites, and certain species of brachiopods or foraminifera. These organisms help geologists and paleontologists correlate the age of rock layers across different regions. Their distinctive features and rapid evolutionary changes make them reliable indicators of specific geological time frames.
How long must a species have existed to be an index fossil?
A species must have existed for a relatively short period of time (usually less than 10 million years) to be considered an index fossil. This is because index fossils are used to help date rock layers, and having a short existence helps to narrow down the age of the rocks they are found in.

Which are the remains of species that existed on Earth for relatively short periods of time were abundant and were wide spread geographically?
Trilobites are an example of remains from a species that existed for relatively short periods of time, were abundant, and were geographically widespread. Trilobites lived from the Early Cambrian to the Late Permian period, spanning over 270 million years, and were diverse and numerous in marine environments worldwide. Their fossils are commonly found in rocks around the world.
What fossils are the remains of species that existed abundantly on earth for relatively short periods of time widespread areas?
Index Fossil
Is it true that To be a useful index fossil a species must have been rare?

The key characteristic of an index fossil is that it is easily recognizable, widespread geographically, and existed for a relatively short period of time. This allows geologists to use it to help date the rock layers in which it is found.
What are the 3 characteristics of index fossils?
Index fossils help scientists figure out the plants and animals that were alive in a certain time period. There are different types of index fossils that are used for different amounts of time.
What criteria are used to identify index fossils?
An index fossil must be of a rapidly evolving organism that only existed for a specific period of time, is easily recognizable, is abundantly preserved, and was widespread geographically. Most index fossils are therefore of marine organisms.
What characteristics must a fossil have to be useful as an index fossil?
An index fossil must be of a rapidly evolving organism that only existed for a specific period of time, is easily recognizable, is abundantly preserved, and was widespread geographically. Most index fossils are therefore of marine organisms.
What is an important characteristic of an index fossil-?
a. pex: it might have lived in a very wide geographic region

Why was there a widespread unrest in the 1780's under the confederation congress?
They was widespread unrest in the 1780's under the Confederation Congress because they found out werewolves and other lycanthropes existed.
How many different major cultures of Native Americans existed on the American continent in 1500?
Major cultural differences are designated geographically, such as: Southeastern, Plains, Northeastern, and Coastal. (There ARE more)
Is the dodo bird an index fossil?
Yes, the dodo bird is considered an index fossil, although it is not commonly used in geological dating due to its relatively recent extinction in the late 17th century. Index fossils are typically species that were widespread, abundant, and existed for a brief geological time period, which helps in correlating the age of rock layers. The dodo's distinctive characteristics and limited time frame make it useful for identifying specific periods in the Holocene epoch. However, it is more often referenced in discussions about extinction and conservation rather than formal geological dating.
