What are these?

[PleaseW84myRX8]

Do you know what these are? I found them outside at a local park. This tree dropped a bunch and many of them were torn up. So I was wondering if they were edible. But since I didn't know what they were, didn't want to eat one. I live in Reno, NV if the geography is necessary, but I know a lot of the trees here aren't native.

It's an Osage Orange. It's also known as a hedge apple.

Squirrels love the seeds, which is probably what tore them up.
I think the seeds are edible for humans - but you might want to check me on that.

It's an Osage Orange.

Great, thank you.

Osage Orange (Maclura pomifera) is an unusual deciduous tree in the Mulberry family (Moraceae). The family relationship is clear as the fruit of Maclura pomifera bear a close resemblance to those of such related plants as breadfruit (Artocarpus altilis), though those of Maclura are not edible.
There are several tropical members of the genus, Maclura, with at least one species occurring on each tropical continental region of North America, South America, Asia, and Australia. However, Maclura pomifera is a relictual outlier, occurring natively only in the U.S. states of Texas, Oklahoma, and Arkansas,. Osage Orange is remarkably cold hardy (to -30º F/-34º C) considering its close tropical relatives.
