how did carcharodontosaurus go extinct? When did the Carcharodontosaurus become extinct? These dinosaurs probably became extinct during the Turonian Age, which took place right after the Cenomanian of Late Cretaceous.

When did Carcharodontosaurus go extinct? The last definite members of the allosaurs, the Carcharodontosauridae, went extinct around 90 million years ago, during the Late Cretaceous Period [3].
How do sea otters help the environment? Sea otters help ecosystems capture carbon from the atmosphere and store it as biomass and deep-sea detritus, preventing it from being converted back to carbon dioxide and contributing to climate change.
What happened to the environment after the sea otters disappeared? Since the otters disappeared, sea urchins have proliferated and mowed down the seaweed. In the meantime even the reefs, which were created over very long periods of time by crusty red algae (about 0.35 millimeters vertical growth per year) and which the kelp once used as substrate, are in danger.

Extinction is more likely to occur with rapid, large-scale environmental change, because species do not have time to adapt to the changing conditions. The fossil and geologic records show us that human induced changes in the Earth system have caused extinctions, especially over the last 200 year.
