Phacops rana is considered a good index fossil because it lived during a specific geological period, primarily the Devonian, which allows geologists to date rock layers accurately. Its widespread distribution and distinctive morphology make it easily recognizable and useful for correlating the ages of different rock formations. Additionally, it existed for a relatively short geological time span, enhancing its effectiveness in identifying and dating specific strata.
was an english scientist who lived at the same time as vanleeuwenhoek
We would conclude that the bird and the dinosaur lived around the same time.
The layer most likely to have organisms that lived at the same time as a specific bear species would be the one corresponding to the same geological time period in which that bear existed. For example, if the bear species is from the Pleistocene epoch, then the associated layer would contain fossils and remains from that epoch, indicating contemporaneous organisms. Typically, this would be a fossil-rich stratum within the same geological formation or sequence.
Sedimentary rock is the most likely type of rock to contain fossils of animals that once lived in the ocean. This is because sedimentary rocks form from the accumulation and compaction of sediments, which can entomb and preserve the remains of organisms over time.
Different animals
A fossil that is likely to be found in the same age bedrock as Centroceras is a marine organism such as other types of algae, foraminifera, or marine invertebrates like brachiopods or ammonites. These organisms lived in similar environments and time periods as Centroceras, making them common in the same age bedrock layers.
No! Although this is a common mistake, all dinosaurs were land animals. All animals that lived in the sea at the same time as the dinosaurs weren't actually classed as dinosaurs even though they have similarities :)
Yes, all animals we have now lived then, just some that lived then have gone extinct so we don't have them now.
I'm not sure about plants, but animals that lived at the same time as the saber toothed cat would be: Terror birds, early humans, woolly mammoths, woolly rhiocerous. ~ ~Sleenky
Two people who were alive at the same time in history lived in the same era.
dogs
The Maya of Mexico lived around the same time as the Mound Builders
Queen Victoria and Abraham Lincoln lived at the same time as Charles Dickens.
Stegosaurus lived 80 million years before Triceratops evolved. They were both herbivores, so they wouldn't have been natural enemies even if they had lived at the same time. If they had lived at the same time though, they probably wouldn't have been "friends" either, because most species only form relationships of any kind with animals of their own species.
Well, most of the time geologists find fossils of plants and animals, and then study them to find out how long ago the plant(or animal) lived.
