    Sharks are pretty perfect

    Perfectly tasty for an orca whale :)

    Megladon :p

    As it turns out, it has been thypothesized that orca whales played a part in the downfall of the megalodon, out-competing and possibly predating upon their young.

    A Tv documentary recently put forward that there was a large toothed whale that hunted Megalodon in packs. Not an Orca but an earlier version. I can't remember the name of the creature I am afraid, but I know one of you will have heard of it.

    Yeah that paleontologist / interviewee guy they have on it is quite the head wrecker.

    Or this... scavenging but shark-eating at the end of the day. I have a better pic of a hyena eating a shark in my computer but, I think you can´t upload directly from your hard drive to the forum?

    The big Dunk is really just a tiddler you know.

    I think some of those shark eating fish may have been this fella too:

    As soon as I get my printer fixed I would like a copy of that.

    Thank you very much Cap'n.

    Some serious messing about with sizes going on in that pic if they are meant to be somewhat to scale.

    Leedsichthys looks in the 80 foot range in that pic. All recent studies on it have put it in the 30 - 35 foot range with a few saying it may have had a maximum size of 50-55 foot.


    The Archelon in the pic looks to be three or four times longer than the human, but the largest ever fossil remains were from a specimen estimated to be about 13 foot long.

    The pic is from Tim Haines' Chased by Sea Monsters, which is from the same "litter" as Walking with Dinosaurs. I have the Walking with Dinosaurs book and it explains how the series creators would often base their creatures on undescribed and fragmentary remains. For example, Stegosaurus is officially "only" 9 meters long but there were fragmentary remains found in the US that suggested that larger individuals, probably up to 12 meters long, had existed. So of course they embraced this maximum estimate. They did the same with Diplodocus, Ankylosaurus and Ornithocheirus, and more famously with Liopleurodon.
    So I wouldn´t be surprised if this was their modus operandi with Chased by Sea Monsters as well.
    Even so I don´t think the pic is all to scale; the Xiphactinus looks almost as long as the Elasmosaurus and the "Megalodon"...

    Because nobody has ever found a complete Leedsichthys skeleton, it’s not clear how big, exactly, Leedsichthys Problematicus grew. Modern estimates put it at 50 to 75 feet long (16 to 22 metres), making it the biggest fish ever – bigger than the Whale Shark or the Megalodon ! Not everyone agrees, however


  • Registered Users Posts: 30,747 ✭✭✭✭ Galvasean


    The Xiphactinus is way too big. He could swallow a human like a pea!

    Those estimates are based on old research. Pretty much all research since 2003 has them in the 30-25 foot range with the possibility of a few 50-55 foot outsized specimens. The 60, 70, and 80 foot estimates have long since been discounted and put down to overestimation and incorrect scaling up from fossil finds.

    To be honest I think that poster is one of those things they pin up in a school for science class. None of the sizes look right really.

    Thanks for the info Kess.

    280 million years ago back in the Permian there was mesosarus it looked like a croc so it may have gobbled the odd shark too

    how long have remoras been around ?

    I think the oldest are from the Eocene. Could be wrong tho...
