What caused the Pliocene extinction?
Approximately 2.6 million years ago (Pliocene epoch), a tsunami of cosmic energy from a massive supernova or a series of them about 150 light-years away reached Earth and pummeled the atmosphere, touching off climate change and triggering the mass extinction of large marine animals, according to University of Kansas …

What major events happened in the Pliocene epoch?
Though a relatively short epoch, tremendous events occurred during the Pliocene, such as the development of ice caps, the drying of the Mediterranean, and the joining of the Americas. Biogeographically, this epoch is characterized by the dramatic modernization of mammals.
How did the Megalodon go extinct?
Extinction of a mega shark We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. As the adult sharks were dependent on tropical waters, the drop in ocean temperatures likely resulted in a significant loss of habitat.
What was Earth like in the Pliocene?
Pliocene environments were generally cooler and drier than those of preceding epochs, as revealed by the remains of plants and trees, but marine records indicate that an interval around 3.0–3.5 million years ago may have been a relatively warm period, at least in the North Atlantic.
Are Megalodon’s still alive in 2021?
There is no record, they completely vanish. The only valid conclusion is megalodon became extinct. This shows the evolution of the megalodon, from a small Cretaceous shark to the apex predator of the Pliocene. After the Pliocene, megalodon fossils are no longer present.
Is it possible for a megalodon to still exist?
But could megalodon still exist? ‘No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it.

What are the two theories on the Pleistocene extinction?
The cause of the extinctions has been vigorously debated, with two main hypotheses being advanced: (1) the extinctions were the result of overpredation by human hunters; and (2) they were the result of abrupt climatic and vegetation changes during the last glacial-interglacial transition.
What caused megafauna extinction?
The Megafauna extinction is probably due to human influence (largely hunting) alone. The climate had changed many times (there had been nearly 30 previous glacial/interglacial cycles without similar extinctions.
What animals went extinct in the late Pleistocene extinction?
The end of the Pleistocene was marked by the extinction of many genera of large mammals, including mammoths, mastodons, ground sloths, and giant beavers. The extinction event is most distinct in North America, where 32 genera of large mammals vanished during an interval of about 2,000 years, centred on 11,000 bp.
What ended the Pleistocene epoch?
The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The Pleistocene is the first epoch of the Quaternary Period or sixth epoch of the Cenozoic Era .
