These Concretions are found in the Taylor river. They are eroding out of a clay bank along the side of the river. When my son and I first found the site, the concretions on the bank were on pedastals from rain erosion! Wish I would have had a camera. These specimens are the way mother nature made them. Except for the 2 that were painted by my daughter. It is just a short hike down the river from the road.
