Stretching from Montana to New Mexico over 150 million years ago, the Morrison formation is famous for its abundant sauropod population, from Camarasaurus, to Diplodocus, to the most notable among them, the mighty Brachiosaurus!
That means the bird, Pelagornis chilensis had one of the longest wingspan ever recorded–a wingspan that was about as long as a giraffe is high, with 17 feet or 5 meters. It cruised the skies between 5 and 10 million years ago.
Pelargonis sandersi, boasted a 21-foot 6.1 meters wingspan, dwarfs that of today’s biggest flier, the royal albatross, whose span measures a “mere” 11.5 feet (3.5 meters). And it rivals that of the largest flying bird on record: Argentavis magnificens—a South American condor with a 23-foot (7-meter) wingspa
Pelargonis chilensis is still my fav fossil seabird
