I guess you're right. :-) Since A. fragillmus' bones are lost, we can only
compare Cope's old drawings with A. altus' remains. But Cope's drawings were
pretty detailed and good aren't they (unlike Bruhathkayosaurus' drawings,
LOL), so we could come to a more or less solid conclusion. Looks like Ken
did that, meaning that if, a big if here, his theory is correct, then A.
altus is the well 'normal' species of Amphicoelias. That means that the
giant 60 m one is an abnormal species. If that's true, Amphicoelias isn't in
the list of the largest dinosaurs. This is really your branch, Mike.
