If you see one near your base and tames kill it or tame it quickly. I first time one came it was pretty far and I thought it would be fine so I went out destroying fish with my sarco for sake and when I came back I found the therizino attacking my carno. I fired darts at the theri just in case my carno was outmatched and the theri died. My carno was on 23 health and if he didn’t kill the theri then my base would of been destroyed and he would kill dusky the para that somehow took on a carno.
