You will notice two very different formats on this page. The most obvious is thatthere isno "0X" image. The reason why is because of the size of the individual grains. These are not sand grains; they are pebbles. I couldn't get an accurate image of the entire assortment with my lens. Second, the label on the container stated that there were "vertebrate fossil fragments" in the collection along with Phosphate pebbles. The sample was collected from a boat wake swash zone. Enjoy the hunt! |
