They are called index fossils, an aid to relative dating of rock.

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.

Index Fossil


Are index fossils the remains of species that existed on earth for relatively short periods of time?

Yes, index fossils are the remains of species that lived for short periods of time geologically. They are useful for dating and correlating the age of rock layers.


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.

What is the difference between have someone and had someone?

If you have someone, the relationship exists at the current time. If you had someone, the relationship used to exist but no longer does. (If you have had someone, the relationship existed for a period or for periods in the past. If you had had someone, the relationship existed for a period or for periods in the past but ended at some point in the past.)


What are the warm periods that occur between ice ages called?

The warm periods that occur between ice ages are called interglacial periods. These are characterized by higher temperatures, melting of ice, and a relatively stable climate compared to the colder ice age periods.


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.


Is a pterodactuyl a dinosaur?

A Pterodactyl (or Pterosaur) is not actually a dinosaur, but a winged reptile that existed alongside the dinosaurs from the late Triassic to the Cretaceous Periods.


Were all the suffragettes in prison?

No; only a small number of their leaders, and those usually only for relatively short periods.
