      Dieser Asteroideneinschlag ist doch nur ein Gerücht, das die Globalisten in die Welt gesetzt haben, um uns alle schwul zu machen!

        Globalisten? Ich dachte die Techno-Nekromanten von Alpha Centauri?

        Birds originated in the Jurassic, and could (can) fly. Some dinosaurs could fly. Pterosaurs are lizards, who also could fly.

      They are the direct sister group. It’s kind of a definition thing. People defined dinosaurs before pterosaurs were known so they were not included

        it’s not really a definition thing as such, “dinosaur” just means anything descended from a specific point on the tree of life.

          Yes, dinosaurs are defined as all descents of the last common ancestor of [blank] and [blank].

          I don’t remember what the blanks were but I’m sure they would have included pterosaurs if they knew about them back than

              I understand quite well how monophyletic clades work and I hope you understand that they are a human construct. That doesn’t mean they are wrong or bad or something, but the question you are ignoring is: Who decides what the stem dinosaur is and would the decision be the same if they know about pterosaurs? Maybe but maybe not. Now that decision is made and set in stone, there is no going back but “dinosaur” and “ornithodiran” are just words that would be swopped (again, not gonna happen anymore)

    ‘This post is a palaeontological disaster’ is a marvelous turn of phrase, and I intend to steal it for use at the first opportunity.

    The funny part about this is…

    We do know what some of them sounded like. (Well I forget which ones so, maybe they’re not Dino’s, but uh, yeah.) (also, big “maybe” attached. They took 3d scans of what they think are the vocal organs and ran air through a 3d printed version.)

      That was an exaggerated bit in the Lost World movie, but vocalizations are mostly done with soft tissue, which isn’t fossilized.

        They found a fossilized Anklyosaurus larynx, which is what I 3d printed.

        I got the file from a chain of friends passing the STL along, and highly-scientifically printed it in TPU and ran some air through just for the fun of it.

        It sounded like a squeaky fart and was worth about of laughter and jokes. My nephew may have been at the age of fart jokes and not knowing when they were dead.

      well almost, we don’t know what they sounded like but we can make pretty decent educated guesses at what they probably sounded like in general.

      For example parasaurolophus very definitely seems to have a resonating structure, like a trombone strapped to their face, so it’d be weird if they didn’t make some sort of trumpeting sounds.

      Another big one is that dinosaurs generally didn’t have anything like a voicebox or whatever the thing is that birds use to make their calls, so we can be quite confident that most dinosaurs didn’t make any bird-like noises, and they wouldn’t have been able to do stuff like roar either.

      Which leaves us with t.rex probably just having sounded somewhat like an alligator.

      I think there was also something about taking modern bird sounds and pitching the accordingly to body size and the fossilized vocal structures? Too lazy to look it up right now though, might as well have dreamt it.

        They definitely 3d printed their larynx- I know this because they published the model and I printed it in TPU.

        It sounded like a squeaky fart. (But I’m guessing TPU is nothing like the appropriate material.)

    Here’s half an hour of reconstructed dinosaur sounds.

    An ongoing study utilizing the most recent scientific data on dinosaur vocalizations. Sounds are produced by myself and digitally workshopped from modern non-syrinx based avian reptiles. Using skull and olfactory cavity proportions, one can attempt to recreate the flow of sound, frequency, and volume of each animal. Much study is required for each particular species, and often several phases are trashed due to general unlikelihood. The final results are based on acute representations of what sounds would be most comfortable and base-line for each animal. Video also includes other reptiles, even though they are much more difficult to produce accurately.

    I just read in a podcast that studying the effects of Helium in our throats helped us understand better the acoustics of our throats, and from there we also gained some understanding into how other animals, including dinossaurs, sound like.
