[PW] Children's book about a pterodactyl

[Robin Carroll-Mann]

This is for me.  I'm trying to identify a children's book I read in the late 1960s/early 1970s.  It was fiction, an easy reader, not (I think) a chapter book, with simple illustrations in browns and greens.

The book was about a dinosaur couple trying to protect their egg from a menacing pterodactyl.  They were referred to as "Mr and Mrs Brontosaurus" or something similar.  After being driven away several times, the pterodactyl dives down at high speed -- and smashes against the egg-shaped stone that the parents had placed in the nest.

The first line of the book is something like, "Once upon a time, 150 million years ago..."

I don't know why, but the book has been sticking in my mind.  None of the children's librarians I work with have been able to identify it  Can anyone here scratch my mental itch?
