The extinction of megalodon set the stage for further changes in marine communities. The average body size of baleen whales increased significantly after its disappearance, although possibly due to other, climate-related, causes. [119] Conversely the increase in baleen whale size may have contributed to the extinction of megalodon, as they may ...
The Pleistocene extinction model is the only test of multiple hypotheses and is the only model to specifically test combination hypotheses by artificially introducing sufficient climate change to cause extinction. When overkill and climate change are combined they balance each other out. Climate change reduces the number of plants, overkill ...
A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction. Scientists find new clue in what led to megalodon’s demise Skip to ...
Marine mammals likely constituted a big part of megalodon's menu, so with it gone, they were free to thrive. Observations indicate that in the years since the mega-shark's extinction, baleen ...
Numerous extinctions occurred during the latter half of the Last Glacial Period when most large mammals went extinct in the Americas, Australia-New Guinea, and Eurasia, including over 80% of all terrestrial animals with a body mass greater than 1,000 kilograms (2,200 lb). Small animals and other organisms like plants were generally unaffected ...

The Bramble Cay melomys, thought to be the first mammal species to go extinct due to the impacts of climate change [9] A 2013 paper looked at 12 900 islands in the Pacific Ocean and Southeast Asia which host over 3000 vertebrates, and how they would be affected by sea level rise of 1, 3 and 6 meters (with the last two levels not anticipated ...
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...
