In fact, as _Psittacosaurus_ occurs in the Yixian Fm., a unit that seems to
be Barremian aged (due to Swisher et al.'s new radiometric dates), it is
older than the Apt./Alb. Aussie ceratopsian-like ulna.

There is no evidence of this. I expect this is a mix-up on the part of the
press, the rock shop owners, and others involved. I expect that the buyers
were told that they were "ceratopsian eggs" or "_Protoceratops_ eggs", which
phrase was mutated into "_Triceratops_ eggs". (Whether they were actual
ceratopsian eggs is another matter entirely: at least some rock shop owners
are unaware of the previous work reidentifying traditional "_Protoceratops_
eggs" as oviraptorosaur eggs).
Keep us posted on new details.
