Quite seriously, CAN ANYONE TELL ME RELIABLY (preferably with references)?:
(1) Has any seemingly HATCHLING (not 'junior sized' but just-after-hatching size) articulated dinosaur fossil ever been scientifically described that was recovered from EAST OF THE MISSISSIPPI RIVER in the U.S.A.?
(2) Has any articulated seemingly HATCHLING Nodosaur -- or, even more broadly, any hatchling Ankylosaurian -- ever been documented (preferably scientifically described in publication) from ANYWHERE? Pawpawsaurus campbelli, e.g., simply does not qualify, being far too large to be a hatchling.
And, quite un-seriously: The 'cryptonomen' for Cryolophosaurus should be: Aintnothin'butasaurus houndogi. :^O
