Dr. McAllister et al -

        Can you provide a reference for these tracks?  I haven't heard of
them.  I _do_ know, however, that Keith Rigby, Jr., of Notre Dame and his
crew are working on what he believes to be not only articulated dinosaur
skeletons (hadrosaurs) but intact nests and eggs in the Paleocene of
southwestern (I think) China.  Little if anything has been published on
these yet, as all his analyses of the relevant ash beds is taking a

        Already, though, many people are (rightfully, to my way of
thinking) doubting his findings -- the attribution of these skeletons to
the Paleocene is based on some iffy vertebrate associations of the
dinosaurs with Paleocene mammals.

OOO f the Earth's many creatures, not all did survive.
O   O Only those that adapted are today still alive!
OOO Those that couldn't -- or wouldn't -- are with us no more:
The most famous of these is the great dinosaur!
"Evolution," they call it; a 10-dollar word.
That's how nature, in time, from a fish, made a bird.
