Tetradium

Just today after taking picture yesterday I found out the specimen in NW corner is Hesperorthis tricenaria, my first positive id of the bottom portion. Might will have to retake pics in the near future as bottom portion of orthids are more similar than I thought. Plus the other challenges of orthids is more species maybe exist in twin cities Decorah than previous reported for some weird reasons. Seem like middle and upper Decorah formation have the most of the rarer orthid genus.
