Please I.D. a Tree
When I was a child in the early 1960's, in southern California, there was a tree up the street from my Grandma's house that dropped large pods on the sidewalk. The pods were hard, dry or dried out, shaped like a canoe, dark brown and about three inches long. The pods were open, like a canoe's inside. They hurt when stepped on with bare feet. I think there was yellowish fiber-y stuff on the inside but I'm not sure.
