Asked in Extinct Animals, The Difference Between
How does the background rate of extinction differ from mass extinctions?
The background rate of extinction is much smaller than those that occur during a mass extinction. For example, carnotaurus sastrei went extinct during the mid-Cretaceous, when only a handful of dinosaurs went extinct. On the other hand, 65 million years ago, all dinosaurs went extinct during the K/T mass extinction event.

Why is it important to protect endangered species?

Asked in Saltwater Fish, Prehistoric Animals
Why did the placoderms go extinct?
Placoderms appeared in the fossil register during the Silurian period, and all placoderms (including the nightmarish Dunkleosteus terrelli) went extinct on the Late Devonian extinction. On the Carboniferous period there were already no placoderm fishes in the oceans. This Paleozoic era extinction(s) is not yet fully understood. However, the extinction of many marine life families in the Devonian/Carboniferous mass extinction, during the Frasnian/Famennian stages and specially the Kellwasser event, was due to the widespread oceanic anoxia. Few other reliable paleontologic data is known.

Asked in Biodiversity
Why is an ecosystem with a high biodiversity is considered to be more stable than an ecosystem with a low biodiversity?
What statement describing a cause of extinction includes the other three?
Asked in Pterosaur (Pterodactyl)
Why did the Pterodactyls die out?
Pterodactyls died out along with the dinosaurs and many other animal and plant species during the K-T extinction event. It is believed that an asteroid, along with other environmental changes, struck the Earth and contributed to the mass extinction. Dinosaurs, pterosaurs, and many marine reptiles were not able to cope, so they went extinct.

Why it is important for an animal to have more than one source of food?
Asked in Extinct Animals
How does mass extinction change conditions for species that survive?
How does the extinction of animals affect the earth?
How many extinctions has earth experienced in its history?
Asked in Elephants
Will the extinction of elephants directly impact other forms of life?
Yes. The extinction of elephants may cause many other animals too become extinct too. As an example, many kinds of wild cats are the predators of the elephants. If the wild cats has no food then they will become extinct as well. In the food triangle of animals this will show that many different animals need each other to live.
The effects of extinction of animals?
positive effect is that on the extinction of a specie, a new area and food source is now accessible to other species. the negative effect is that when a specie become extinct, the specie which has an close relationship with that specie tends to loose its grip of survival and fall into extinction too.
Asked in Dinosaurs, Extinct Animals
Is this true or false an extinct animal is one that lived in the time of the dinosaurs?
It is true that most animals alive during the time of dinosaurs are now extinct. However, any animal can go extinct, even in modern times. For instance, the pallid beach mouse went extinct in 1959. The Pyrenean ibex went extinct in 2000. The eastern cougar went extinct in 2011. Extinction simply means there are no animals of that type left. They have all been wiped out through hunting, deforestation, illness, or other reasons.
