Brontosaurus Prints

[WolfBard]

Okay are these just really rare, or on a particular level of the Savannah cave? I've been mining the caverns for two whole in-game months with every other print (including pterodactyl) showing up for me. Still have not hit brontosaurus.

I've got a boatload of fossil nodes and tried opening a few but got no prints so I'm assuming they don't show up there once they unlock in game.

I think they're really rare? So when I found one while getting to floor 125 and finishing the giant quest, I simply replicated the other four. Sorry the RNG gods are being so difficult.

Dino prints do not unlock in fossils. They just drop by themselves. At least once you find one you can can pop it in the slime of replication for the rest you need.

Hey. I know this is two months old but I had the same problem.
The good news is Brontosaurus Prints do exist, you can get them the same way as the other prints, they randomly drop in the Cave of Memories in Savannah. They seem to be very rare - I have already unlocked all of the other holograms before I came across the first print for Borntosaurus. Luckily once I found just one I could simply put it in a Slime of Replication, which I recommend for anybody who struggles with this.
