Could these be Podocarpus seeds?
I've found these near an old podocarpus tree. Thou I didn't see them on the tree, they were below some bird nest, so I presume that the fruits must have been eaten along with the seeds, but couldn't find on the web a decent picture of the clean seed alone... all pictures seem to be of whole fruits.
If they're not Podocarpus, any clue what other thing could they be.
Thanks and regards. Paul.
