What happened to the species that are now used as index fossils?
Index fossils are typically chosen due to their widespread distribution and short-lived existence, making them useful for dating rock layers. Many of the species selected as index fossils in the past may have gone extinct due to changing environmental conditions over time, while others may still exist but have evolved significantly from their ancient counterparts.
What are the ways that fossils helped support of the continental drift?
Fossils of the same species can be found on continents that are now today separated by oceans. btw continental drift is a fact.
How do fossils help explain continental drift?
Fossils provide evidence for continental drift by showing that similar species or species that were once connected are now found on separate continents. For example, identical fossils have been found on continents that are now widely separated, supporting the idea that these land masses were once part of the same larger landmass. Additionally, the distribution of fossils of ancient organisms can also suggest how certain species were able to migrate across continents when they were closer together.

How do scientists know that some places that had once been under water are now deserts'?
Fossils of fish and other aquatic species have been found where the desert now is.
How do fossils help explain the theories of evolution?
Fossils give us a lot of information about species which used to exist on Earth but which are now extinct. With this information we can see in greater detail how species have evolved over time.
How the principle of uniformitarianism and evidence from index fossils supports the existence of Pangaea?
well cant say how uniformitarianism would support it but as far as index fossils go think about the fact that a for a single species to survive on multiple continents at same time it would need the same environment and apparently its not the case now but Pangaea was a single continent @ one place with single environment. so if any index fossils spread across multiple continents point towards them being of same environment and the most logical explanation is them being at the similar lat-long which sort of points us towards the idea that is Pangaea!

What are Types of fossils found from continental drift?
Fossils found as evidence of continental drift include similar species of plants and animals on continents now separated by vast oceans, such as the Mesosaurus, a freshwater reptile found in both South America and Africa. Additionally, fossils of the ancient plant Glossopteris have been discovered across continents like Africa, South America, Antarctica, and India, supporting the idea of a once-connected landmass. These fossils indicate that the continents were once joined, allowing species to inhabit a continuous environment before drifting apart.
Why do fossils provide evidence that many species of organisms that lived long ago are now extinct?
Fossils serve as crucial evidence of extinction because they represent the remains or traces of organisms that lived in the past, allowing scientists to study their physical characteristics and distribution. When fossils of certain species are found in sedimentary layers that are no longer inhabited by those organisms, it indicates that those species no longer exist. Additionally, the fossil record shows a pattern of diversification and disappearance over geological time, highlighting mass extinction events and changes in biodiversity. This cumulative evidence confirms that many species that once thrived on Earth have since vanished.
How does scientsis now that to cassify organism is fossils?
you tell me
Where would you find most fossils?
well,you sometimes find fossils under the sands and they were alive but now dead
