What are other organisms that went extinct during the mass extinction?

∙ 6y ago
Many types of large reptiles died out, along with non avian dinosaurs, during the K-T mass extinction. These include pterosaurs, plesiosars, mosasaurs, and marine crocodylomorphs. Ammonites, a highly successful group of molluscs, became extinct. On land, scientists believe that no species larger than a housecat survived.

How are extinct organisms related to other extinct organisms as well as living organisms?
By the way they look, (their bone structure, body weight) and DNA too.
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 are higher levels of biodiversity good for ecosystem stability?
The higher the biodiversity, the higher the number of species, and the lower the rate of extinction. A decrease in biodiversity means a single species will become extinct and this will have a negative impact on other organisms for all organisms in an ecosystem are connected.
What are the extinction rates of terrestrial and freshwater organisms?
The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
What might have caused the mass extinction at the end of the paleozoic era?
The mass extinction, known as the Permian extinction, affected both plants and animals on land and in the seas. Scientists do not know what catastrophic events caused the mass extinction, many kinds of organisms suddenly became extinct, as much as 90% of Marine species may have died out.
Do dolphins face extinction?

What is the name for the happening that makes things extinct?

What problem does a hole in the ozone cause for humans and other organisms?
A hole in the ozone is a big threat. It can cause humans and other organisms to extinct.
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.
What statement describing a cause of extinction includes the other three?
member of extinct species lacked adaption essential for survival
Why did the pterodactyl die?
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.
What does the Eastern hare wallaby eat?
The Eastern Hare-Wallaby is extinct. Prior to its extinction, it ate grass and other native vegetation.
