World's Biggest Underbite Came Before The Dinosaurs!
495The world’s oceans have changed dramatically over time. We live in a world in which the oceans are dominated by giant mammal and fish predators. Go back to the Mesozoic and its various families of reptiles. Go back to the Paleozoic, and you get gradational ecosystems of all types of weird animal groups calling the shots. From the Silurian to the Devonian periods, fish finally evolved jaws with teeth to crunch up the invertebrate animals around them, allowing them to take the top rungs of the ecological ladder. New remains of one of these fish have been found and show it to be unlike anything from its group every found. Let’s meet Alienacanthus.
