I try to give you various ideas for the new dino (I'm very excited !!), if you want to make a carnivorous dinosaur you could do the Siamraptor, because it would add a new dinosaur the size of a Carno-raptor. but I would be happy to see some new extinct mammals, perhaps glacial. it should also be mentioned that it would be interesting to have another large dinosaur that rules rivers and lakes, such as the already famous deinonichus or others. I hope it has been a little useful to you!
