What wood is this

Seems to hard to be pine

Picture is too close up. Need an end grain shot. Looks like poplar at first glance.

Pores look like red oak

kinda looks like a type of pine, but also mimics a type of beech. Does it smell like pine? That'd be the giveaway.

As a matter of fact I sniffed it many times but just didn't get that Pine smell, so IDK.
Dark now can't take a picture of and grain.
By the way that piece is a 4 x 6 part of a big pallet

Is it heavy wood? If so, I'm saying possibly beech.. those little brown flecks remind me of beech, but beech shouldn't be in palletwood, so its probably a conifer.....not any poplar I ever saw.
