back to article Dinosaurs were DRAINED of blood by GIGANTIC HORROR FLEAS

As if impending extinction wasn't enough, dinosaurs were also plagued by giant mega-fleas that impaled their soft underbellies and feasted on their blood. Illustration of prehistoric flea Nom, nom, nom, nom... The super-fleas, which were around ten times the size of the fleas that bother dogs nowadays had an extra-painful …

    There's a really unpleasant bit in Will Ferrell vehicle Land of the Lost where he gets drained by a massive blood sucking insect. Am I the only person who finds Ferrell not as funny as everyone says he is?

    Anna Friel in shorts though, cor.

      Actually, just thinking about it, ten times bigger? Modern fleas are only a few millimetres long, so they'd not be that massive would they? Maybe 15 - 30mm long?

      /squirts Frontline on back of neck, just to be sure.

        Nuke them from orbit...

        That would still be a blood-sucking-malaria-infesting-aids-transmitting-one-inch-plus-long creepy crawly.... Imagine your dog covered in asian hornet sized insects, but hungrier...

        15 to 30mm is... 1.5 to 3cm, or approximately 1 inch. A flea one inch long? No thanks!

        not that big not but imagine 2000 of the jumpy jumpy little blood suckers comming after you cause Fido been sucked dry..

        I would be packing the can of raid with the attached zippo

    I can just hear a couple of surviving dinosaurs having a conversation

    <Yorkshire accent>

    "When I was a lad, we proper fleas, not these miniature little things that cannot bit through a piece of paper if they wanted to!"

    "Right you are! I remember fleas that could bite right through a Triceratops's scales, he could"

    "That's nothing, I saw some fleas that could drill straight through an Ankylosaur's club, no less"

    "Rubbish, we had fleas which could drill for oil, they could, bite so strong it would go a mile through solid rock, it could!"

    "And the problem with kids these days is that when you tell them they don't believe a word you say!"

    grain of salt

    I've always been told that insects can not be 'very large' because of the fact thaty they don't have longues but a completely different 'breathing system' that requires them to remain small.

    So they can't have been 'football' size, but they can be 'ping-pong' ball sized.

      Re: grain of salt

      There used to be more oxygen around.

      It took some time for the parasites (that's us, the non-photosynthetic organisms) to suck the excess oxygen from the atmosphere. Looks like there was a window of opportunity for extra-large parasites.

    3. Allan George Dyer

      Re: grain of salt

      And your point, Kleykenb? There are plenty of modern insects larger than this, there's a 3cm hornet that regularly visits my lounge, for instance. I wouldn't like to get attacked by either... I'll leave the hornet be until the gecko gets it, and the flea, well, 65 million years in the bedrock should do it.

    I doubt it would have been that painful. Any pain would result in the parasite being brushed off, whereas it would have preferred to remain undetected.

    Big flea

    The paper says 22.8mm for Pseudopulex magnus. VS ~2mm for a modern flea

    That's close to an inch in old money

    Been done

    I vaguely remember a brilliant SF short story from the 1960s (I think) called something like "Poor Little Hunter". A brilliant scientist invents a time machine and (as one would) jumps back to the Cretaceous to shoot a brontosaur (as they called them in the 1960s). He drops a big specimen - about 60 tons - with his first shot, and is just going for a closer look when he sees some creatures racing towards him from the dead dino's direction. Moments later he is hit by half a dozen dog-sized parasites, which chew him up in seconds leaving little but a few bones.

    Moral: (1) respect the ecosystem - especially if it's in your own distant past - and (2) it's not always the big animal that is the real threat.

      Re: Been done

      Close -- I recall the story but not the author. Tourist time-travel was common and Claude, whose wife was named Maude, decided to bag a big dinosaur. (He was not the inventor of time travel.) After shooting the creature and watching its head slowly sink into the muck, he is disappointed in the anti-climax and turns to leave but is knocked down by something landing on his back (followed by a few others).

      Nevertheless, good morals.

    Not wishing to pour scorn on this but if I got speared by a flea it'd be like being bitten by ... err ... a flea. Now, if I was the size of a tyranno-whatsit and I was bitten by something much bigger than a flea it'd surely be, relatively speaking, like being bitten by a large flea?

    Did the artist bother reading the desription before drawing it?

    Description: flat-bodied, long claws holding onto scales.

    Picture: plump-bodied, short claws holding onto skin with feathers.

    Or maybe El Reg has (mistakenly) chosen a stock image of a modern flea to illustrate the article?

    Either way, someone has stuffed up the picture.
