Giant Dinosaurs Were Fastest Growing Animals Ever 64

sciencehabit writes "Lufengosaurus, a long-necked, plant-eating dinosaur that lived in China during the Jurassic period, were the biggest animals of their age, measuring 30 feet long. Now, fossilized embryos reveal that they were also the fastest growing animals on record — 'faster than anything we have ever seen,' according to one researcher. What's more, researchers have found traces of organic matter in their bones, which may belong to the oldest fossil proteins ever found."

    Giant Dinosaurs Were Fastest Growing Animals Ever

    Obviously they haven't heard of Cowboyneal

  • If they are the fastest growing animal ever, it seems like the perfect candidate for efficient protein source farming. I mean, come on, what could possibly go wrong?
  • How would they know if a dinosaur fossil is from 1 year old or 2 years old? Carbon dating isn't that specific. They'd be guessing that a dinosaur was fully grown at X amount of years and then sort of backtrack it but it's basically a complete guess.

      I think it's quite safe to assume that the dinos this study is dedicated to are less than one year old, as this is about dinos that were still in their eggs.

      OTOH I'd guess it's normal for a dino to multiply it's size while still in the egg. Just look at human babies, they grow like a hundred times in length and something like a thousand times in weight from the moment they're recognisable as human (arms, legs, head) until they're born. After birth they grow only about four times in length and some 20 times

      First off, carbon dating is only good for the latest couple tens of thousands of years. After that the percentage of C14 is so small that randomness takes over.

      What they would be looking at is the internal morphology of the bones.

    The article doesn't mention much about how fast they really grew.

    How long did it take them to reach adult size, for example?

    And related: what was the approx. lifespan of such animals?

    How could they manage the food intake for that growth? This are plant eaters, and plants are not the most efficient sources of energy - leaves are pretty hard to digest, especially compared to meat. So they must eat a lot of it (probably pretty much constantly), and have a rather efficient digestive system that can handle the huge quantities of food.

  • Maybe chicken tastes like dinosaur
    • Considering that chickens are the closest living relative to dinosaurs, I wouldn't be too surprised if they did. Of course, serving a Pterodactylus wing would mean placing a 2.5 foot wing on the table.

  • "Fastest growing animals ever" HA!

    You need to come to my home state and take a look at some of the mammals we have here. They truck around in their motorized wheelchairs in the isles of Walmart.

    C'mon, we've all seen it, you toss the capsule in the bathwater, and BOOM, you got yourself a dinosaur in a few seconds, how is this news?
