DiscoveryIn 1932 a scientist named Gunnar Save Soderbergh lead an espedition in Greenland to find fossils. He found over four species of a new kind of large amphibian, and named it Ichthyostega, or "fish roof", since the top of its head seemed to resemble that of a fish. Gunnar noticed that each species differed slightly in skull proportions, punctuation, and bone pattern.
AppearanceAlthough Ichthyostega certainly had amphibian-like qualities, there's been some debate as to whether or not it actually is one or just a very advanced lobe-fish, since its skull still had very fish-like features. It was very large for an amphibian, reaching lengths of over 5 feet (1.5 meters) long. Its head was flat with large eyes and powerful jaws with sharp teeth that would've been helpful in keeping a grip on its struggling fishy prey. It likely had a smooth, slimy body to help it go through water easier, keep it hydrated, and absorb oxygen easier. It also had a long, strong tail that helped propel it through the water and either catch prey or stay ahead of predators. One feature that sets Ichthyostega apart from most amphibians is that it had seven digits on its hind feet. Like others of its kind, it had webbing between its toes to help with swimming.
In Popular Culture
Ichthyostega had a small role in the second episode of Animal Armageddon, where it shows how it looked, acted, and lived compared to its ancestor Tiktaalik after the Devonian Extinction.
Ichtyostega appears in Jurassic World: The Game as a legendary amphibian. Ichtyostega is unlocked by beating it in battle stage 38. It can either be free through Legendary card packs or purchased with 3,330 DNA.
