What should I switch out?

Here is my current team

I have a new unboosted level 16 Dracoceratops. I’d like to use it on my team, but I don’t know what to switch it out for.
Here are the roles of the creatures on my team;:
Brachiosaurus and Diplodocus: health tanks
T. rex: big hitter
Indominus Rex: revenge killer
Compy: Good flock
Monolometrodon: versatile cunning fierce
Woolly rhino: high damage swapper
Thylacotator: bleeder and render

Probably Diplodocus Or Brachiosaurus…

Brachiosaurus.

Trex is pretty much useless. I would replace it with dracoceratops.
