40 Trikes imo.
80 Velociraptor: Canon fodder, might get a few nibbles at best
25 Quetzes: Apart from their beaks they can't do anything to get past a trike's defense. Even less of them than the trikes lol.
60 Ekrixes: Only big carnivore here, still gets eviscerated but definitely does more damage than the previous 2.
50 Peloroplites: Probably too slow for their armor to be of any use, most Ankylosaurs get low diffed by Trike anyway.
200 Hylonomus: Just happy to be there.
Really the only things that can do any damage here are the Quetzes and the Ekrixinatos. Unless the 85 of them can somehow pull of a coordinated attack the Trikes are gonna slaughter everything else.
Edit: I did not know Peloroplites was that small
Oh my days
