Not really. Most of the IOW prints are visible because they are infilled with
clay or sand of a different colour. It's not so much that the print/cast itself
is only mm thick: most of the sst prints are pretty darned thick, up to a foot
or more (!) and often show 3d twisting of the foot etc. really cool actually.
The clay prints are still 6 inches deep or more: about what you'd expect for a
large animal stepping onto soft mud. These thick prints get slowly serially
sectioned by the erosion of the tide, and can look not-much-like prints once
they get a little eroded.
Some iguanodon footcasts:
and I have US14 (UK13) size feet for scale.
There's a big range of tracks visible there.. sauropods, ankylosaurs, theropods
and ornithopods of different sizes: thing is the big iggy prints are the most
As for size - with the bigger beasts

Yes they can.
And anyway.. the footprint described as t-rex from new mexico, is certainly
theropod, and the sheer size of it would suggest a large tyrannosaur.
