I found my first one at HERBIVORE ISLAND ( on mobile ) and i lost my level 30 meg with 1000 health and lists of damage to multiple megs but my bary killed the mega due to them having low heath thanks to Maggie my meg, now I’m using my bary to kill the manta’s and a diplo to give me oxygen ( I’m level 52 ) and I’m gonna game a basilo now XD
In real life these were vicious carnivores that would have killed and eaten a human on sight and lived mostly in shallow waters and swam up rivers looking for food they were also twenty metres long, good thing the developers didn't make them more realistic or crossing rivers would be a dream until you have a flyer.
This is one of those tames that is flawless this is why:oil generator, immunity to being shocked by jellies or electric eels,squid grabs,very powerful healing when near surface and it's only weakness is the deep but it's worth it
Trilobites take up a place in their spawns so you’ll need to go and kill them as well as the Coelacanths, Megalodon, mantas and Leeds to get them to spawn if they haven’t already. I’d suggest looking along south coast of The Island and especially around Herbi Island.
