On Val you can find them around Lat 74.2 and Long 87 just look for their burrowss. They are mean and babies seem to be as well.

You can encounter them in open plains on several maps i just dont have an exact list of maps

I've had a lot of luck with flat grassy areas on Valguero

Just look for a mound of dirt on the ground; the burrowbuck (or burrowdoe!) will be nearby

I happened to come across a burrow but with 2 Trex wondering about which I despatched,the adult burrowbuck got killed, I acquired one baby and just tamed the second one, obviously from the same litter and about to cryo it after taming and another Trex came from nowhere and wasted the 2nd baby.

Tip need words

If they have a baby they will try to murder you and you tames stay safe :D
