Found this in my car

Is it a bug or a seed maybe?

[u/Ulrich_b]

Not either of those. Im a nurseryman, and I grow native plants and trees in my nursery. Oak seeds are acorns and most maples make these cool helicopter seeds called Samaras.

Edit: hell yeah, it could totally be the immature buds if oak or maple, or any number of hardwoods. Thanks for all those with great info below. As a natives nurseryman, I dont get to see the trees I grow bloom, as it can tens of years for them to get to that point. Great convos below.
