I'd appreciate some assistance identifying a tree I just came across.

In Northern Ohio, zone 6A 6B.

Not a Bush but a small tree. As it is currently still early March tree is still dormant and rather unremarkable. It's bark is somewhat Maple-like.

No leaves, berries or buds, etc. No leaves found on ground.

I don't know when they dropped but all around its base are dozens of Pods.

They are dark brown, dry. They rattle. No Pulpy material inside. Nothing but 8 to a dozen small seeds within each.

About 1" wide and roughly 8" in their curled state. Straightened out each would measure approximately 12" long.

I assume it to be in the Fabaceae or Leguminosae family but have not yet been able to find a good match. I don't recognize it as anything I've seen before. I do not believe it to be a Locust, Mimosa, Redbud, Catalpa, Kentucky Coffee Tree.

I should have included something in the photos to reference size. The individual seeds are approximately 7/16" in long.

Thanks in advance for any info.
