The really cool thing about that brach plate Kevin, is that it looks like at one time to have extended over a really large area I'm finding little pockets scattered around the exposed rocks there and all the brachs weathered out of the matrix just laying around.


Two photos of the Early Ordovician (Ibexian) Hesperonomiella minor Shell Bed. Shells average about 1cm wide. This bed is found over a large area of Utah and Nevada. Paleozoic shell beds are mostly composed of brachiopods while after the P/T extinction they contain mostly bivalves. Looks like you may have a shell bed in common with hallucigenia.
