Final proof of dinosaur endothermy?
Good day,
I'm not sure if this was already posted, probably wasn't. In the June edition
of a (czech) scientific magazine 21. stoleti (21st Century) is interesting
article by paleontologist Martin Kundrat and writer Jaroslav Mares dedicated to
the long forgotten fossil foot imprint of a sitting dinosaur located in the
Pratt musem (?) in Amherst, MA. Its catalogue number is PMNH-EHC 1/7. The full
article will be presented in July's edition of Journal of Experimental Zoology
(Part B: Molecular and Developmental Evolution). There is not much info, but
obviously the find shows imprints of a primitive feathers located in the pelvic
area of sitting theropod. Yeah, BTW, the find is 200 Ma old. There are also
preserved imprints of a rain drops falling down from the feathery integument of
the animal. "Feathers" of this dinosaur are very similar to those of an ostrich
fetus before hatching. It has second stage of a feather development according
to Plum's scale (?). This is animal with a feathery
integument 55 Ma older then Archie. Sorry for poor translation. Vlad
"Micropachycephalosaurus" Socha
