Therizinosaurus is a household dinosaur name compared to the rest, so it'd be the most likely option to bring in guests.

Only one of these is not a mod

I voted tarchia because with the theri you can't keep it with anything as it will try murdering it and with its in game stats being as high as they are going to kill them even sauropods, irritator is my second choice, then megatherium then concavenator then astrodon

Can you ping me the cmnts Conc?

Sure

Also to those who wonder what the next animal selection is it is first aviary animal that is not a hybrid as I found a pterosaur hybrid mod

As much as I love Irritator, I will go with Concavenator. It looks so cool
