I regularly eat bunya nuts from the Australian bunya or false monkey puzzle tree (Araucaria bidwillii). It is said to have appeared in the Jurassic (~200 - 145 mya). They are very tasty.
For people that dont know these, think pine cone thats a little bigger than a bowling ball. They are pretty amazing looking things.

(There’s a smallish bunya-bunya near my house, but I don’t think I’ll try gathering nuts from there myself…)
