Auspex Posted August 15, 2011 Share Posted August 15, 2011 Unknown, because of the fossil record is so scanty; I think 4" smaller might be possible (young bird, but how could one know that?), but 4" larger would be beyond the normal range of differential among the neorniths.

Auspex Posted August 15, 2011 Share Posted August 15, 2011 Also could the sediment also factor in the enlargment and or reduction in size? Absolutely, which is why the artful science of ichnology considers tell-tale clues of such in a track plate.

Auspex Posted August 15, 2011 Share Posted August 15, 2011 There is the original impression, which is concave, and it's counterpart (formed when the original is covered and filled) which is convex. "Part" and "counterpart" when the rock is split.
