Ok so there is this tree on a corner near my home. I don't have a pic of the tree, just what falls from it. Its on the border of a vacant lot so I can't hope to see the owner and ask them. I noticed all over the sidewalk next to it these " leaves " I'll call them for lack of a better way of describing what they really are. They fall off the tree, they look like large thick wooden daisy petals . I collected a ton of them in a bag and its been sitting in my " to do craft bin " for awhile. Im thinking of painting them and gluing them together to make a huge piece of art for over my couch. I've never seen something that looks like this fall off a tree. Any idea what kind of tree it is?

of course my dog needs to check everything out
