You can see all confirmed upcoming creatures here, which includes some on your list: https://fossils-archeology.fandom.com/wiki/User_blog:Adsper/All_Possible_Mobs

I can deconfirm pretty much all of the Dromaeosaurs, since it's confirmed they only have four planned (Microraptor, Austroraptor, Deinonychus and Velociraptor). This probably counts for the Troodontids too. They're trying to add a variety of mobs rather than many similar ones.

Oviraptor, Baryonyx, Suchomimus and probably the other Spinosaurs are confirmed not to be planned as well, for the same reason. I'm also pretty sure I remember them saying they only have one more Tyrannosaur on their list. They do have an "eventually" list with more stuff which may include more Spinosaurs/Tyrannosaurus/Dromaeosaurs, but that's so far away there's no point in thinking about it.

Nanotyrannus, Troodon, Hypselosaurus and Angaturama won't be added because they don't exist any more. Might be a few more on the list like this too.
