More Prehistoric Mobs

I think we should have more prehistoric mobs like the sniffer like 1 or 2 it doesn't need to be like a t-rex or something like that. I think a small and docile one would be cool and a big hostile one that we'd be able to tame and ride it and since the sniffer is already red i think the hostile mob could have huge claws or something with blue feathers since the sniffer has moss on his back, and the docile mob could be green and would have wings to fly like the alley and would plant a new pink prehistoric flower when he touches the ground, or maybe just plant a seed every 10-20 minutes.
