Today the Wooster Geologists of Team Jurassic Utah visited Early Triassic rocks near Hurricane, Utah (N 37.041054°, W 113.273450°). These are rocks of the Virgin Limestone Member of the Moenkopi Formation. I wanted to show the students the abundant brachiopod fauna in these sediments deposited relatively soon after the massive Permian extinctions.
The brachiopods are tiny and gray. I completely missed them in the talus slopes until Nick began to pick them up. He trained us to recognize them quickly. Above the mysterious Vicky Wang scours the slopes.
