There have been six or seven "Great Dyings" in Planet Earth's biological history. All of them resulted in extinctions of some sea life. You may be thinking of the K-T Event, which exterminated the amorites as well as the dinosaurs.
This is picky, I admit, but I suspect you mean Ammonites, not Amorites. The Amorites were a group of Semitic peoples who lived in the Sumer area of the near east some 4 thousand years ago.
Just FYI, the greatest extinction pulse occurred at the end of the Permian Period and closed the Proterozoic Era with an enormous die-off of life on earth. More than 95 percent of all organisms vanished with the end of that era. Paleontologist are still trying to hypothesize conditions that might explain such an enormous catastrophe.
What else can I help you with?
Animals of the mesozoic extinction?
During the Mesozoic extinction, some of the animals that went extinct included non-avian dinosaurs, pterosaurs, marine reptiles like ichthyosaurs and mosasaurs, and various marine invertebrates. This extinction event was primarily caused by a combination of volcanic activity, climate change, and possibly asteroid impact, leading to the demise of many species that could not adapt to the changing environment.
How might overturning contribute to the extinction of marine animals that live in surface water?
Overturning can impact marine animals in surface water by disrupting their feeding patterns, exposing them to predators from deeper waters, reducing oxygen levels, and altering their habitat conditions. This disturbance can lead to decreased survival rates, decreased reproductive success, and ultimately contribute to the extinction of these marine animals.
What period did most marine animals become extinct?
Most marine animals experienced significant extinction during the Late Permian period, around 252 million years ago, during the Permian-Triassic extinction event. This event is considered the largest mass extinction in Earth's history, with approximately 90% of marine species going extinct. Other notable marine extinctions also occurred during the Late Cretaceous period, around 66 million years ago, which led to the demise of the dinosaurs and many marine reptiles.
Are mosquitoes responsible for the extinction of the dinosaurs?
Mosquitoes in modern time are know to pass parasites and deceases. This was also probably true in ancient times as well, maybe some kind of dinosaur malaria. However although this may have contributed to the deaths of individual dinosaurs (there is absolutely no evidence for this) it is not thought that this is a contributing factor in the extinction of all non-avian dinosaurs. Most telling is the extinction of the large marine reptiles such as mosasaurs. Since they were completely aquatic it is unlikely that mosquitoes could have caused their extinction. Another clue is the lack of extinction of small animals. Mosquito born diseases would not have just attacked the larger species and leave most of the smaller ones alone. The most popular current theory suggest that at the end of the Cretaceous saw a great increase in volcanism. This would have changed the environment causing climate change and also would have "poisoned" the environment. The non-avian dinosaurs were living in a dying world. To make matters worse a 6 mile wide asteroid hit the Yucatan Peninsula in what is now Mexico. This caused global fires as rock ejected into orbit by the asteroid started to fall back to earth. It also caused a "nuclear winter" which made many species of plants to die out. This was just too much for dinosaurs and other animals to cope with. Mostly the only animals that survived this extinction were all under 10kg. They perhaps were animals that lived underground or where able to shelter away from the fires.
What types of organisms does the WWF protect?
The WWF stands for the World Wildlife Federation. It is their mission to protect endangered species of animals to prevent extinction. They deal with all types of animals - primates, marine animals, and big cats.
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.
Mass extinctions of marine species are believed to have been caused by which event?
Mass extinctions of marine species are often attributed to significant geological and environmental events, such as volcanic eruptions, asteroid impacts, and drastic climate changes. For example, the Permian-Triassic extinction, the largest mass extinction event, is thought to have been driven by massive volcanic activity that released greenhouse gases, leading to ocean anoxia and acidification. Similarly, the Cretaceous-Paleogene extinction is linked to an asteroid impact that caused rapid climate shifts and disrupted ecosystems. These events collectively resulted in the loss of a substantial number of marine species.
Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
Who are the marine animals?
marine animals are sea toads & more!
What was the first major extinction event?
First major extinction (c. 440 mya): Climate change (relatively severeand sudden global cooling) seems to have been at work at the first ofthese-the end-Ordovician mass extinction that caused such pronouncedchange in marine life (little or no life existed on land at that time). 25%of families lost (a family may consist of a few to thousands of species).
What happened to many land and sea animals at Paleozoic era?
During the Paleozoic era, many land and sea animals experienced significant evolutionary changes and diversification. The era saw the emergence of early fish, amphibians, and reptiles, as well as the development of extensive marine ecosystems. However, it ended with the Permian-Triassic extinction event, the largest mass extinction in Earth's history, which wiped out around 90% of marine species and a significant number of terrestrial organisms. This extinction dramatically reshaped the biological landscape and set the stage for the Mesozoic era.
What event occured about 250 million years ago and caused about 90 of the species living in the oceanto become extinct?
About 250 million years ago, the Permian-Triassic extinction event occurred, marking the most significant mass extinction in Earth's history. This event led to the extinction of approximately 90% of marine species, largely due to catastrophic environmental changes including volcanic eruptions, climate shifts, and ocean anoxia. The scale of the extinction dramatically reshaped marine ecosystems and paved the way for the rise of new species in the Triassic period.
