Just a couple semi-random questions, because I’ve been discussing these issues with friends.
Question the First
Is the Blue Whale really the largest animal that has ever lived on Earth? This statement dates back from the days when Brachiosaurus was considered the heavyweight of the dinosaurs, and it would have been true then. Blue whales average 25 meters long, and I recall that the largest ever found was a 29 meter female.
However, we now know about Seismosaurus. Seismosaurus averaged from 39 to 52 meters long, yet you still always see the dogmatic assertion that the Blue Whale is the largest creature ever. Now obviously, a respectable amount of the Seismosaurus’s length is comprised of the iconic neck and tail - maybe even half of it. But they still have mass, so even if you divide a 52 meter dinosaur’s length in half to 26 meters, with some mathematical additive factor for the neck and tail, wouldn’t you still end up with something larger than the record Blue Whale (let alone the average)?
Question the Second
Does anyone seriously believe that Tyrannosaurus really had those puny little arms, utterly tiny and useless proportional to its body? I mean, come on, that’s not evolutionarily advantageous - it might not even be able to get back up if it fell. No other carnosaur, or dinosaur in general, had such a “feature.”
I am personally inclined to think that one of two things happened. Either a baby tyrannosaur’s arms got put on the body of an adult; or the arms of a prey animal or other miscellaneous dinosaur that was jumbled in with the tyrannosaur’s bone’s got put on the T-Rex’s body. In either case, I believe it is a serious mistake. (Isn’t there only one “complete” t-rex skeleton - “Sue” or somesuch?) Do I have any basis for thinking this?
Thanks for listening to the semi-rant and hopefully for responding.
