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.

THANKS FOR READ THE TIPS
