Even disregarding the later, I will tell you what I logically conclude from
this. I have been asking myself if these footprints could have been
produced underwater and I have concluded probably not. The reason is that
there are footprints from many different dinosaurs of different sizes. It
seems to me that the water depth has to be just right for a dinosaur to be
swimming along and leave a trail of prints and that same water depth will
not allow for smaller or larger dinosaurs to efficiently leave prints. I
would have to propose wildly changing depths of water over time in order to
account for the variety of prints. Is my logic way off, the only thing I
can come up with otherwise is that all the prints were made by the same
animal but at different times at different depths of water (thus the weight
placed on the sediment varied giving what appears to be different prints).
Anyway, I thought this particular discovery might be worth keeping an
eye on for future developments.
