Is it possible that the eggs were leathery like some lizard/snake eggs and
that
fossilization calcified (or otherwise hardened) the shell pieces?

Considering the egg size to thickness, how does this compare with say an
Ostrich
egg? Are the ratios of overall size to shell thickness similar? Emu or Moa
eggs?

Just an amatuer amazed by such thin shells on such a huge egg.
