Those acorns are similar in appearance to Bur Oak acorns. Only not as big.
I'd love to have some Bur Oaks, and planted some acorns here a couple years ago with no results. They were gathered acorns, and may not have been prime..
I'm not sure that I know what a Bur oak is... we have overcups, but they grow right next to the water, so I dont figure that is what you are talking about. Are the bur oak acorns larger than the saw tooth? The overcup acorns are almost if not as large as the sawtooth and deer love them.
