These are easy to knock out, Just get a bow and a bunch of trans arrows, Then keep shooting it and running away so it wont hit you, Then feed it mejoberries and then wait... Theres your bronto thanking you because you tamed it.
Whoever it was who said one pushed them off a cliff for no reason. That was a diplodocus not a bronto diplodocus are small and have straight necks and pointy teeth for stripping leaves off of bushes and ferns while brontos are big with bendy necks and kind of beak like mouths for snapping leaves and twigs put of the canopy.
Bronto are slow just shoot shocks or tranqs and walk backwards. Use large rocks to jam them they struggle to cross non flat terrain. Use EXCEPTIONAL kibble to tame high levels or you will be waiting 5-10 min even from starve using berries or veg.
Bronto can carry as many people as you like with or without platform saddle aslong as weight limit is not exceeded. (There is no seat for passangers to mount)
