Then, about 600 years ago, they abruptly went extinct. In fact, the resemblance is close enough that paleontologists once thought the fossils of Dorudon were actually fossils of Basilosaurus when they were younger. She has a bachelor's degree in ecology and evolutionary biology from Dartmouth College and a graduate certificate in science writing from the University of California, Santa Cruz (2018).

Which group of mammals evolved around the same period of time as Dorudon? This comes as a surprise asmodern-day sharks can self-regulate their body heat and adapt to their environments. Further, humans introduced invasive species that outcompeted the dodo for food. Dodo: Raphus cucullatus. Heinrich Harder (1858-1935) For millions of years, nine species of large, flightless birds known as moas ( Dinornithiformes) thrived in New Zealand. Flight of the dodo.

The change in vegetation and climate may not have been adaptable for the cold-blooded dinosaurs and caused many of them to die over time. At best, researchers can only hope to produce an animal that has some mammoth features, rather than resurrecting an extinct species. A few hunded years ago, map makers' drawings of sea beasts weren't that far off from the real -- and extinct -- creatures that once swam the oceans. Finally, as the explorersexploreddeeper into the island, the natural resources were exploited and harvested, which harmed not only the dodos, but other endemic species and plantsultimately paving the way for the extinction of this eccentric bird.
