"These animals do not have any teeth, and since they
are ready to hatch, that is strange," said Robert
Reisz of the University of Toronto at Mississauga in
Canada, who led the study.

"The only explanation for that is they must have
been fed by the mother. That would be oldest
evidence of parental care in the fossil record,"
Reisz added in a telephone interview.

Or that the young ate different material from the
adults. Parental care is not the only answer.

What could they eat if they really had no teeth at all? (There's no evidence for a beak in *Massospondylus*, contrary to earlier hypotheses.)
