Are Megalodons 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.
When did the Megalodon disappear? Fossil evidence suggests that megalodons went extinct before about 2.6 million years ago, during a period of cooling and drying in many parts of the world. These changes may have been related to the closing of the seaways separating North from South America and Eurasia from Africa.
Is the Megalodon confirmed extinct? Megalodon is definitely extinct—and great white sharks may be to blame. Megalodon were the rulers of the ancient oceans. The massive creatures grew up to 60 feet long and sported jaws more than six feet wide.

Extinction. The Trophy System is also available in Extinction mode, where it is simply called “Trophy”. Its main function is to destroy the Gas Cloud attacks from Scorpions. The Trophy will not be attacked by Cryptids.
what is global extinction crisis?
The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
what is the difference between a dormant and extinct volcano?
Active volcanoes have a recent history of eruptions; they are likely to erupt again. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.
when did the dodo extinct?
The dodo was extinct by 1681, the Réunion solitaire by 1746, and the Rodrigues solitaire by about 1790. The dodo is frequently cited as one of the most well-known examples of human-induced extinction and also serves as a symbol of obsolescence with respect to human technological progress.
how will bee extinction affect humans?
We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the amount of fruit and vegetables.
what if wolves went extinct?
If wolves went extinct, the food chain would crumble. The elk and deer population would increase (see chart on next slide) and eat the cow and other livestock’s food. Then we, the Humans, would have a food shortage in beef and dairy and possibly shortages in other food products too.

Why we should bring back extinct animals?
When the species was lost, the forests lost the main driver of their regulation cycle and have never been the same. Reviving extinct keystone species, then, could help us preserve biodiversity, and, possibly, the ecosystems as a whole.
Why did the saber tooth tiger become extinct?
Scientists theorize that environmental change, decline in prey population, and human activity lead to the death of the saber-tooth tiger some 10,000 years ago.
Will oysters ever go extinct?
The European native oyster (Ostrea edulis) population has declined by 95% since the 1950s, and oysters are now extinct in some regions of Europe, such as the Wadden Sea along the coast of Germany. Removing these vast ecosystems has deprived the sea of essential services, reducing water quality.

What is global extinction risk?
The extinction risk of climate change is the risk of species becoming extinct due to the effects of climate change. Climate change is the long-term conversion of temperature and average weather patterns. Currently, 19% of species on the IUCN Red List of Threatened Species are already being impacted by climate change.
