The largest extinction of species occurred during the Permian-Triassic period, approximately 252 million years ago. This event, known as the "Great Dying," is estimated to have wiped out about 90-96% of marine species and around 70% of terrestrial vertebrate species. Factors contributing to this mass extinction included volcanic eruptions, climate change, and ocean anoxia. It marked a significant turning point in Earth's biodiversity and set the stage for the rise of the dinosaurs in the subsequent Mesozoic era.
What else can I help you with?
When all the in individuals of a species have died what is it called?
The death of every member of a species is called extinction. When a large number of different species is dies out at the same time it is called mass extinction.
Disappearance of many species at the same time?
extinction
When doe extinction occur?
Extinction of a single species can occur at any time if said species in hunted excessively, but mass extinction only occurs every 27 to 33 million years.
What is the a period of time called when many species disappeared?
A major extinction event.
The largest extinction the world has ever known occurred at the end of which period?
The largest extinction event known is the Permian-Triassic Extinction Event, 250 million years ago. It is nicknamed "The Great Dying" in reference to how 96% of all known marine animals and 70% of all known terrestrial vertebrates at the time went extinct due to climatic changes because of volcanic eruptions and the formation of Pangaea.
What term describes development of new species and a mass extinction?
Evolution is the term that describes development of new species and mass extinction. Over time all living thing have evolved.
Whats a gradual change in the characteristics of a species over time is?
Evolution.
What is background extinctions?
A background extinction is the continuous extinction of individual species caused by climate change, disease, loss of habitat, and competitive disadvantages against other species. Background extinctions occur at a slow rate over time, affecting only a few species at one time.
Which term is defined as a species dying or becoming extinct in a very short time?

What is the large-scale disappearence of many species within a short time called?
