More Brontosaurus Stories Tips
I had a great Bronto named Bob, He was great and reliable. I always gathered berries and wood for my tribe. Bob was an absolute beast in combat. He could easily destroy high level Rexes. One sad day, I returned to base. I was on an Argentavis and was flying around. I saw a few strong dinos heading straight to our base. We were about to get raided. They attacked us and shred our base. We fought them with our dinos. Bob started to shred through them. Bob bought us enough time to escape. He fought until his last stand. R.I.P Bob
This has been my experience taming dinosaurs (It's so so sad)
One time I tamed Bronto lvl 12 on Herbivore island, it only took about 23 tranq arrows (no more than 30), after that I gave him 100 Savoroot and 72 Longgrass, then I went to normal island, then I wanted to find some explorer notes (I left Bronto because the torpor time was 2 hours 15 minutes 53 seconds (about 44 minutes for taming), so I left him with 172 crops, when I returned. BRONTO AND ALL MY CROPS ARE LOST.
So never leave the dinosaurs you want to tame even though it takes a long time.
