    Isn’t this a while thing? Where archeologists have drawn alternative interpretations of what dinosaurs could have looked like. I think there was a famous example, where red they got people to.draw a dinosaur from a hippo skeleton and the creature was really scary looking?

    Interesting thought, but don’t penguins have feathers for insulation from cold weather so without the feathers they probably look less chunky.

        They probably have some fat as well, but penguins are mostly insulated by their special feathers, which are adapted to prevent the cold water from actually reaching the skin.

          They definitely do but my point was that the actual volume is from the fat so they are very much fat chonkers. The feathers are laid on top of each other to be waterproof so they don’t really make up volume. You can check the pic below for reference (I am not sure how to add embed sorry).

          Penguin feathers

          I am not sure which would he primary insulator but fat definitely helps a lot and pretty commonly found in other animals for the same purpose. You can also see some featherless penguins in zoo are given cute little jackets lol.

            their circulatory system is also pretty adapted for them, thier blood vessels usually can do countercurrent exchange of heat, rete mirabilis, this is common in cold adapted creatures. so they technically dont lose heat when it goes near the skin surface.

        penguins do have one of the densest feathers per square centimeter of any bird.

    Kind of hard to maintain that bulk on leaves and grass, bud. I guess it would help them with predators, though.

      Hippos and rhinos get pretty big on that diet! If anything plants are a better diet for something really chunky because plants cannot run away

        The largest land animal today is an african elephant which is 14 feet tall. Brachiosaurus was 50 feet tall. They would need to eat an order of magnitude more because the cost of mobility increases with weight.

        Penguins, seals, and whales (and to a lesser extent hippos) can maintain this ratio because it gives them bouyancy while travelling in water.

        Plus, Hippos and Elephants are actually pretty big boned.

          They would, but they also did. They were herbivores

          To be clear I do not actually think that they were as stocky as that pic. Point is that for land animals, though, eating plants actually is often the way to being huge

          Sauropods had hollow bones and air sacs all throughout for lightweight structural support. You can’t just compare sizes and assume similar density as elephants or other large mammals.

        Lion’s eat Wathogs, Gazelle, Zebra and sometimes birds.

        Giraffe and Elephants are likely to kill a lion.

        Also an elephant’s height is like 14 feet max. Brachiosaurus height was 50 feet.

      They have a good idea how much the big sauropods might have weighed based on fossilized foot prints and bone structure. Still, if something is not preserved in the fossil record it will not be shown in reconstructions.
