Brush Uconn suggests some simple parental behavior  may have
occurred with respect to protecting dinosaur nests from
predation. Crocodilians, of all the reptiles extant, have
one of the most involved parental nest tending repetoires.
The female  builds her nest so that she can see it from a
nearby body of water; she guards it against predators; she
opens the nest when she hears distress calls from within; she
may even crack eggs hatchlings are unable to escape from 
by themselves and she carries her young to water in her
mouth.  Some species tend their brood for a year or more
and while adult males may cannibalize young occasionally 
females generally respond to the distress calls of young in
order to protect them.  In addition if the female perceives
the nest is too hot she has been known to bathe herself in
water and drip it over the nest to effect cooling.  Not all
species build elaborate nests such as the alligatorids
but most do protect their nests and their young from
predation. (references to these behaviors appear in
Grenard,S: Handbook of Alligators and Crocodiles. 1991)
