    The Cretaceous–Paleogene (K–Pg) extinction event, [a] also known as the K–T extinction, [b] was the mass extinction of three-quarters of the plant and animal species on Earth [2][3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.

  3. Human extinction - Wikipedia

    en.wikipedia.org/wiki/Human_extinction

    Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.

  4. Human–dinosaur coexistence - Wikipedia

    en.wikipedia.org/wiki/Humandinosaur_coexistence

    Humandinosaur coexistence. The coexistence of avian dinosaurs (birds) and humans is well established historically and in modern times. The coexistence of non-avian dinosaurs and humans exists only as a recurring motif in speculative fiction, because in the real world non-avian dinosaurs have at no point coexisted with humans. [1]

    Late Devonian: 375 million years ago, 75% of species lost, including most trilobites. End Permian, The Great Dying: 251 million years ago, 96% of species lost, including tabulate corals, and most trees and synapsids.

    They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs. [25] [26] One of the last Plesiadapiformes is Carpolestes simpsoni, having grasping digits but not forward-facing eyes ...

  7. Timeline of Cretaceous–Paleogene extinction event research

    en.wikipedia.org/wiki/Timeline_of_Cretaceous...

    Since the 19th century, a significant amount of research has been conducted on the Cretaceous–Paleogene extinction event, the mass extinction that ended the dinosaur -dominated Mesozoic Era and set the stage for the Age of Mammals, or Cenozoic Era. A chronology of this research is presented here.

  9. Extinction event - Wikipedia

    en.wikipedia.org/wiki/Extinction_event

    The largest extinction was the Kellwasser Event (Frasnian - Famennian, or F-F, 372 Ma), an extinction event at the end of the Frasnian, about midway through the Late Devonian. This extinction annihilated coral reefs and numerous tropical benthic (seabed-living) animals such as jawless fish, brachiopods, and trilobites.
