I found a wild 230 parasaurs what I did was grab mejoberries do the kill 5 mega Phirana quest and did the kill dilo quest then I killed raptors and carnos and Sarcos at spawn for levels and tranqs and then hit it once with the dilo quest bow with tranqs and it was knocked out and I used the balm from the mega Phirana quest to tame it 10% per mejoberrie and this will allow you to even 2 shot knock out a rex and 4 tranq shot all the good maxed 300s exept giga
