The 4 common dinos are those two plus Mammoth and Stegosaurus. As I recall, a simulation I ran said there's about a 50% chance of getting all 4 common dinos from 10 random eggs (guessing their distribution from what I'd gotten, and putting rare dinos at < 1%). My experience from 45 random dino eggs is Stegosaurus 33%, Mammoth 31%, Ankylosaurus 20%, and Parasaurolophus 16%, rare dinos 0%. I think your experience is pretty normal. I had all 4 common dinos after 6 eggs.

I also got a Brontosaurus egg from Bingo (not a random dino egg).

I think I might get more rare dinos from random eggs if I ran a Dino Den farm (e.g. 500 of them running at once). But don't worry, TV only lets you have one.
