I also felt they did not fully address some of Horner's evidence for
long-term occupation of the nest (which need not imply altriciality,
as you say).

In particular I refer to the difference between Maiasaura nests in
which the egg shells are crushed to bits (literally) and Orodromeus
nests where the lower halves of the hatched eggs remain intact.

I seem to have missed this.  JVP, right?    [ No, _Science_. -- MR ]
If I can find time to get to the univ. library again I will try to
check this out.
