sauropods versus blue whales
There are plenty of whale skeletons from the Cenozoic, and there is no doubt
that the blue whale is the biggest ever. It's coincidence, like the moon
perfectly overlapping the sun in eclipses at this particular time (didn't do so
when the moon was closer and soon won't anymore as the moon spirals away).
Although the S Amer titanosaur specimens do not seem to exceed 100 tonnes,
the Morrison Amphicoelus fragillimus vertebrae may belong to a 100-150 tonne
diplodocid assuming Copes description of the collossal and since lost vertebrae
is reasonably accurate. Also, it is not likely that the biggest sauropod
species have been found. So it is possible that sauropod challanged blue whales
in
mass. If just 10% of the super-sauropods body mass was leg muscles - as per
elephants and indicated by the size of leg muscle attachements - then they
would
have had no trouble in locomoting at elephantine speeds.
There are reasons to question the conclusion that the new Canadian
ichthyosaur is as large as blue whales, we must await the description and
detailed
comparisons.
