It is true for at least some species of croc's.
As to dinosaurs, they were an amazingly diverse lot, and it is
unlikely that they all had the same style of parenting. There
is fairly good evidence favor parental care after hatching in
hadrosaurs (in particular, Maiasaura). On the other hand there
is at least suggestive evidence that some groups of dinosaurs
layed their eggs and abandoned them.
The peace of God be with you.
