Quite of these are already confirmed to be coming (Meganeura is coming in the next update.) You can see a list of all confirmed mobs here.

I can confirm however that Troodon will never be added since its no longer considered a valid genus (same might end up being true for Deinosuchus but I'm not really sure what the situation is there.)
