The Trike is a great tame for use in taming large dinos (Rex, Therezino, etc.) What you do is tame a high level one, pump health, and then aggro the Dino you’re taming, start shooting, and slowly move back. The trike will tank due to it’s head armor, allowing you to easily pump tranquilizer into your Dino of choice.
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.
The best way to utilize the trike when tamed or untamed when tamed it can gather loads of berries for you or when it's untamed you can use it as a shield for instance like a carno is running after you and there's a trike try to run for the trike to get the carno to fight the trike so you can escape unharmed
