Squirrels maybe?![]()
Yes, beans and corn both. On a 15th century site near Clyde Ohio. If they are carbonized they survive just like charcoal (because they are). The beans looked like small dried navy or kidney beans. Yours look more like squash or sunflower seeds, also possibilities. Is there evidence of occupation at your site, pottery, fire cracked rock, or a plowed out hearth. If all of the above are absent and the seeds aren't carbonized, then you've dug out a field voles winter food Stache.
Probably left from animal PooP!
On a side note...50 years ago my dad would entertain us kids by saying
"Beans beans, The musical fruit.
The more you eat, the more you toot.
The more you toot, the better you feel.
Let's have beans for every meal."
The version I grew up with was,
"Pork and beans are good for the heart.
The more you eat , the more you fart."
