I made a trap on a tall rock put spine walls around the side that was lower to the ground. Stacked 3 pillars and and put a ladder leading up to the rock. Had a friend lure the thing the the rock while me and a buddy loaded it with Travis arrows. Sadly we knocked it out in the water, which made the tame way harder. Still got it in the end! It is way worth the wait and is a very good tame!!
How to tame, this is a lot easier than most people say it is. The moment you get narcotic arrows you can tame this guy. Step 1: get a strong tame like a trike as long as it has a good health and you can shoot off it. Step 2: Level up it’s health by a lot you will need this in order to tame a Thereizinosaurus. Step 3: get a lot of narcotics and narcotic arrows so the taming process is not hard. Step 4: find a thereizinosaurus and clear the area so no raptors or carnos will get in the way. Step 5: saddle up your Dino and ride over to it. Now the process begins, once your in range pull out your bow and start shooting. Once you hit it will agro on you and start running to you but just keep shooting. Once the thereizinosaurus is within melee range it will start attacking. You need to stand you ground and continue shooting. If you Dino has a lot of health it won’t be a problem. Eventually it will run away from you now you chase it down shooting it until it’s knocked out. Then enjoy taming.
If this dino spawns near your base and you are low and mobile player then just do one thing. Put your all stuff in your base and go near the dino then run in opposite side of your base and lead him to far away from your home before he destroy all you have even your pets. just don't uninstall the game bcoz of this😂
