At the risk of being annoying . . .
My principal reason for giving a different perspective on this varied
from the above poster's: I wasn't so much concerned with whether P.
catodon uses it's teeth to eat the squid, but rather with the comparison
of terrestrial and marine predators itself.

But the physics of terrestrial and marine predation are so different in
virtually every respect that I questioned the usefulness of any analogy
I'm just questioning the proposition that observed characteristics
useful for active marine predation can be used to determine that
"similar" characteristics in a terrestrial animal also suggest (or
defend the notion of) active predation.
Translation: in my opinion, a big swimming head with lots of teeth (P.
catodon) does not function similarly to a big walking/running head with
lots of teeth (T. rex). There are significant differences in
locomotion, presence (or lack) of a bow wave, and a million other
variables to consider. So I don't think that the sperm whale, white
shark or other marine hunters have any usefulness in refuting Horner's
"no arms: no good" argument.
