I can not stress enough to my friends how useful the trike is. Early game it makes a great pack animal. Late game in groups of three or four it can be used as a decent battle mount. Taming a trike early on can be a great way to start a large base and keep you well fed with berries.
A triceratops is a very special dinosaur in this game. It is easy enough to tame at a low level, yet powerful enough to take on raptors that could kill you easily. It can collect enough berries that you would never go hungry again, and still have some berries leftover to help tame more trikes. They are very slow but it can make up for it if you increase the weight, attack, and stamina stats. It is an extremely good pack animal because it can carry a lot, but still defend itself, especially if it is in a large group. Overall, the triceratops is one of my favorite and most versatile dinosaurs.
Tip for any really news players, don’t mess with these guys, there might only be one, in sight, but if you attack one then find out you can’t take it, run back to your base, only to find out 4 more are chasing you and they’ll destroy your thatch base. Don’t attack these guys
Get on a rock, shoot it untill it runs, then attack it on the tail with your fists or club. Make sure the Trike can’t climb the rock you’re standing on. Once it’s out, throw some berries or veggies, that’s how I got Banana Rock and Moldy Orange. (Banana is female, Moldy is male)
Trikes are a great harvesting mount for berries and thatch. They also have good attacks (which do knockback to smaller dinos.) My favorite attack is the charge attack. I use it to raid wood/thatch bases. Overall great mount!
To tame one of those early game you just need to get yourself a slingshot (You can get the engram at Level 5), a low Level Trike (Level 1 - 30) and to be safe around 40 Stones. Then find some Trees and attack the Trike with your Slingshot then use a Hit and Run Technique. It should be much easier because the Trike gets stuck in the Trees and has to get around them. Which gives you enough time to shot him some times with your Slingshot. Once he is unconcious you just have to gather Berries. Use Mejoberries for a higher level after taming. Keep an eye on the Trike's Torpor(You find it in the bottom right hand corner in its Inventory). Once it drops on 0 your Trike will wake up and you have to knock it out again. To raise its Torpor you need to put Narcoberries in its Inventory, click on them and then click on the Remote use item Button (Each Narcoberry adds 8 Torpor). In the Dododex App you can Look how many Slingshot-Shots, Narcoberries and Mejoberries your Trike needs. Good Luck!
