This episode marks the end of our extinction series, but on the bright side, Aly’s here!Most of the extinction events we discuss are very animal-focused, but the end of the Carboniferous Period featured one of history’s worst plant extinctions. This event wiped out the famous ecosystems of the Carboniferous, reshuffled ecosystems, and ushered in a more familiar world of plants. In this episode, as usual, we discuss what happened, why, and how it impacted the world.In the news: a croc-bitten sloth, a dinosaur embryo, dinosaur dimorphism, and ancient hibernation.Time markers: Intro & Announcements: News: Main discussion, Part 1: Main discussion, Part 2: Patron question: Follow Aly on Twitter (@kyrietree) or Instagram (@paleolorax)Check out our blog for bonus info and pictures: http://commondescentpodcast.wordpress.com/New merch at the Common Descent Store! http://zazzle.com/common_descent Featuring art by Rob Soto! https://www.rob-soto.com/Follow and Support us on: Patreon: https://www.patreon.com/commondescentpodcast Twitter: https://twitter.com/CommonDescentPC Facebook: https://www.facebook.com/commondescentpodcast Instagram: @commondescentpodcast PodBean: https://commondescentpodcast.podbean.com/ iTunes: https://itunes.apple.com/us/podcast/the-common-descent-podcast/id1207586509?mt=2 YouTube: https://www.youtube.com/channel/UCePRXHEnZmTGum2r1l2mduwThe Intro and Outro music is “On the Origin of Species” by Protodome.
