The Time Terror Birds Invaded

  • Publicado el 22 ene 2018
  • About 5 million years ago, a new predator made its way from the south and onto the coastal plains of North America. It was a giant, flightless, carnivorous bird and came to be known by one of the coolest and most richly earned nicknames in all of paleontology: the terror bird.
    Correction! Thanks to Ben Creisler for pointing out that at 4:10, we mixed up the Paleogene Period with the Neogene Period. We regret the error and hope you still find these birds as terrifying as we do.

    Please note a correction at 4:10... 5 million years ago would not be the "late Paleogene Period"--it's the end of the Miocene Epoch/beginning of the Pliocene Epoch during the Neogene Period. Titanis is usually dated from the Pliocene to Pleistocene. Interesting video, though.

    I've dreamed about the Terror Bird before I ever heard of it, It was my dream extinct flightless bird and it still is, Although it was alive at some time I stil love them, They are one of my favorite extinct birds. When I heard of Terror Birds I wanted to cry of happiness and no it's not weird or overreacting I just literally made a "made up" bird my favorite flightless extinct bird but, It's real and extinct. I am not lying ._. (Just to let you know.)

    huh, no mention of the one thing I've seen said about them in every single other spot I've seen terror birds mentioned: most species of them that functioned as predators functioned as rushdown predators and had one critical weakness in that regard: they couldn't turn all that well while running at speed, this put them at a big disadvantage anywhere that wasn't an open plane with enough cover for them to get close.
    ironically enough every piece of fiction I've read/watched portrays them as hyper-agile forest predators with a thing for climbing trees.

    Glaciers never made it close to where Titanis lived, but it did start getting colder and drier. There would have been significant floral turnover which may have lead to the extinction of Titanis prey species.

    Mm doesn’t sound right they died out came back years later. Honestly I think it’s just Europeans bringing them years later. Because the South American empires and northern tribes have seen a horse before until the various Europeans came over. Cause would think it would be recorded some how that there were these animals by the people living and that knowledge pass down other people down the line

      chamboyette853 Hace un mes

      I don't think so. I understood that there were species which developed in North America. But it is still strange that there would be no species found in South America even though originally these birds were from there and continued to live there, on top of that in more favorable conditions.

    Just came back from the National Museum of Natural History, and here's what i got...
    There is a pretty good chance that Titanus walleri, the species he focused on, was a fruit eater or scavanger. Think about it. If you compare the skeletons of a modern Ostritch or Emu, and that of Titanis, the bodies don't match up. The leg bones of Titanis, though they supported a much larger animal, are far thicker and broader than what you would find on the modern bird. It would be much more difficult for the bird to reach speeds capable of hunting the deer and horses native to North America at the time. As boring as it may seem, Titanis just doesn't seem to have the body for an "apex preditor" in a land covered by quicker and lighter prey. I think it would be much more suited to the life of a slow plodding omnivore... or in the least an opportunistic preditor like modern flightless birds.
