Dinosaur Knowledge Check DC's

[Ms. Pleiades]

I know that as animals the relevant knowledge skill for a character knowing about dinosaurs would be Knowledge (Nature), but the base DC is something I'm uncertain of. Dinosaurs are kind of an open secret that they exist in the tropical regions of Golarion, but they're still exotic. Is the DC for dinosaurs 10+CR or 15+CR?

[DrSwordopolis]

Up to the GM, of course, but bear in mind that the Bestiary's example for a creature rare enough to be 15 + CR is the Tarrasque. For dinosaurs, I'd go with 10 + CR.

[Ms. Pleiades]

Alrighty then. Thanks.
