A NEW AMPHICOELIAS
PAPER HAS DROPPED!!!
This paper basically sums up that if Amphicoelias
was real and correctly described by Cope, it was absolutely huge. They estimate vertebra height at 2.80 meters, with a centrum 90cm wide, and a femur length of 4.76 meters!!! I'll save the estimates of body size for another post, but that indicates a 70+ meter 150+ ton animal. Anyway, the paper then follows with ecological studies that indicate that such a huge animal is beyond the bounds of it's environment. (I don't buy it)
And that Cope may have made a mistake in his measurements. They propose the 1500mm vertebral height Cope typed should have read 1050mm, which they state is a somewhat unlikely idea. If it truly was 1050mm, the animal still had a 1.95 meter tall dorsal, and a femur 3.3 meters long.
The paper also sinks Amphicoelias fragillimus
into A. altus
, considering it an adult of altus
. They then sink A. altus
into Diplodocus altus
, keeping Diplodocus altus
as the formal name for all Amphicoelias
material. The paper comes with some awesome figures, and includes ontogeny into their estimations. It's a very cool paper, and I suggest taking a look!
Diplodocus may claim the title of the biggest dinosaur ever found!www.voluminajurassica.org/volu…
