Re: Triassic dinosaur evolution
However, if articulation is such that the chest and teeth could not
make contact w/ large prey simultaneously, even under those
circumstances, then the "point" is perhaps not so "good"...
Indeed, that's the issue I'm wondering about. Problem is, I'm not an
expert on the range of motion in the cervical series of large
theropods (I'm much more familiar with the values for the avian
variety, which are very, very skewed by comparison...) But, based on
the information I have, quite a few of the mid to large theropods have
reasonably stiff necks in the sense that a tight S-curve is difficult.
There's also the issue that the prey item needs to be quite large for
there to be any real chance of simultaneous grappling and biting,
which then raises all the usual banter and uncertainty regarding
plausible prey sizes (i.e. did allosaurs really attack sauropods and
