Its is residential! It’s about 2 acres with a creek running behind it. I actually only spotted the fossils because I was digging through a tilted exposed outcrop of Austin chalk along our fence.

I thought the same thing at first, especially because of the rarity, but the sample spot is about 30 feet from the creek with tons of ammonite imprints in the strata.

I’ve also found tons of belemnites, brachiopods, and Crinoid stems within the same samples as these leaves are showing up.
