But after seeing this video were a giant pacific octopus tries to prey on a bald eagle, as well as this video with an octopus dragging a seagull underwater, a feel that it is possible that occasionally the giant ammonites would prey on pterosaurs, snatching them as they dove underwater in search of fish. Given how large they are some theorise Parapuzosia were filter feeders that ate plankton, though it is also possible that like squid and octopi they were predatory and ate mainly fish, crustaceans and smaller cephalopods. Like most ammonites, the shells of this genus are the only known parts, which is understandable considering that their soft, squishy cephalopod bodies wouldn’t fossilise easily, so their exact lifestyle is uncertain. bradyi is not as large, but with a shell around 1.8 meters in diameter it is no small fry either. seppenradensis is the largest of these cephalopods known to have lived, with a shell possibly over 3 meters in diameter. The genus Parapuzosia contains several species of large ammonites, but some were particularly massive. He had seen others of his kind lose their lives to sharks and mosasaurs and had always known to be careful about those, but the predator that gets him isn’t either of those, but a massive ammonite named Parapuzosia bradyi. For one male individual however, today’s flight is his last and when he swoops down towards the surface he is grabbed by a predator. I blame YouTube for not telling me this 3 days sooner and now I am a bit late, but ah well here we go now.Ĩ5 million years ago during the late Cretaceous period of the Western Interior Seaway, a stretch of sea that once ran right across the center of North America, the large pterosaur Pteranodon longiceps glides over the ocean in search of small fish as they’re usually doing. Hey look it’s Ammonite Week! ( youtu.be/rz7pkUK4tHE).
