Not an abstract, just me and my laptop. Inference is
based on some new material. can't say anymore other
than it is really big.
Can you say if it is (a) really _Alamosaurus_; or (b) co-existed with
I would go so far as to say 'Alamosaurus' may have been the biggest North
American sauropod ever (my claim from SVP2004), certainly it gave all the
morrison sauropods a run for their money.
Wow. Like Mike, I find this snippet very tantalizing. When one talks about
Morrison sauropods, you're really in the big leagues: _Amphicoelias_,
_Supersaurus_ (?=_Barosaurus_), _Seismosaurus (?=_Diplodocus_),
_Brachiosaurus_. To be the "biggest North American sauropod ever" is quite
a feat. My apologies to _Alamosaurus_.
Diplodocids were long, but not very heavy for their length; _Brachiosaurus_
was heavy, but not very long. Titanosaurs were heavyset like brachiosaurs,
but tend to have much shorter necks and tails than diplodocids. A better
yardstick might be to compare this new _Alamosaurus_ material with a big-ass
titanosaur like _Argentinosaurus_ or _Pelligrinisaurus_. AFAIK, there are
no Morrison titanosaurs (unless _"Apatosaurus" minimus" is one).
