'Feathered' Sharks Survived The Deadliest Ocean In Earth's History

Sharks have been around for a long time. They have technically been around longer than true trees have – originating in the Ordovician period, while the green woody giants emerged in the middle Devonian. Unfortunately, their cartilaginous skeletons decay to mostly nothing when they die under most circumstances. Only hard parts get preserved. This has left us with a slew of tantalizing bits and pieces of some of the weirdest things to slide through the water. One of those mysterious enigmas of the cartilaginous fish fossil record is the porcupine eel shark – Listracanthus. __________________________________________________________________ Art in Thumbnail belongs to - Joschua Knuppe __________________________________________________________________ ✅ PATREON ✅   / edgescience   ✅ STICKERS & SHIRTS ✅ https://www.redbubble.com/people/Pain... ✅Facebook: facebook.com/ExpeditionDG/ ✅Twitter: twitter.com/NatSciChannel ✅Instagram: @edgeonthetrail ✅ MUSIC ✅ “The Most Extreme Theme” - PastEonsProductions “Astrolabe” - PlatinumQuest OST “Endurance” - PlatinumQuest OST “Ice Cave Chant” - Donkey Kong Country OST “Seaside Revisited” - PlatinumQuest OST “Voices of the Temple” - Donkey Kong Country OST “Aquatic Ambience” - Donkey Kong Country OST “Cave Dweller Concert” - Donkey Kong Country OST “SciFi” - Bensound “Bolt” - Joj’s Bizarre Adevnture Battle Tendency OST “Maze” - Joj’s Bizarre Adevnture Battle Tendency OST “Seinwave” - Abelard “Bargain” - Joj’s Bizarre Adevnture Battle Tendency OST “Fear Factory” - Donkey Kong Country OST “The Most Extreme CGI Scene” - Diario’s Music “Introducing the Pre-Roll” - Lee Rosevere “The Stalker” - Karl Casey “Embers” - Karl Casey __________________________________________________________________ If I've used something on my video that you don't want me to use, PLEASE EMAIL ME first before flagging a video, I'm very reasonable and will take the video down to replace whatever image or video belongs to you.
