    on March 21, 2017 at 1:27 pm

    Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct. […]
