Consider: the fact that preserved eggs and nests exist
at all could argue against global crustal disruptions within the
Quaternary. On the other hand, the sedimentary sites where they are
preserved could themselves, indirectly, argue for such global
cataclysms.
Consider: the locations where dinosaur eggs/nests have
been found in large numbers would have, in the past, been closer to
rather than farther from what was then the equator. So, which equator
locations, and how different from the current equator, do these finds
imply.
This assumes that they have not been transported, in
sedimentary layers, great distances from their original locations,
riding on great forces. On the other hand, what if they were?
Again, underlying all, are the established assumptions
about how far back in time dinosaurs can have existed.
Each yellow dot represents multiple egg and/or nest
finds in each area indicated, sometimes as many as a dozen finds for
each.
Are some of these sites possibly pockets of very late
survivors of earlier mass extinctions? If so, could that point to
climatic conditions implying different locations of the Equator.
If not, has the evidence layer possibly been carried
from somewhere else?
