So what i did was to tame them easy first if u dont need a trap so if they eat fast so what u gotta do is go w ur flyrer drop ur tank combat mount for my case i used my imprinted rex which has 21k hp and killed the carnos make the yuty aggro on it and killed everything hostile and then took it somewhere safe dismounted and let it attack my rex while my rex on passive and js knocked it out using crossbow and tranq arrows and fed it if u need to make a trap and stuff i did the same let it aggro on my rex and bite it while im dismounted and surrounded both of them with metal billboards then proceeded with the tame
