Some of those footprints are supposed to be REAL! I helped collect them along
with Rob Weems, Peter Kranz and employees of the Botanic Gardens ca 1993.
They were recovered from the Pasaic Formation , Newark Supergroup (Late
Triassic I believe though I have seen a recent date of Early Jurassic
somewhere) near Coopersburg Pa. The tracks were principally of the
'grallator' type , all but one were theropod, and we may have even recovered
a prosauropod track but I have never heard what the final word on it was.
Admittadly though, the last time I was at the 'Gardens' I did not see the
tracks we busted our buts cutting but they should be there. I'll check with
Kranz to get the lodown!
peter used to sell T-shirts with the Jurassic forest motif that said "come to
the dinosaur garden", wait... I forgot, I'm wearing the damn thing under my
sweat shirt ...
It says 'come play in the dinosaur garden' and shows a picture of a Nanosaurus
scurrying among the brush. A footnote explains the scene then in big letters
under that are U.S. Botanic Gardens.
I expect to be in DCnext Monday or Tuesday and must see (and maybe buy one or
two) the orchids. Yes another passion which I too am addicted. I even have a
reprint of a paper on the fossil history of the Orchidacea. They may have
evolved in the Late Cretaceous...
