| Here are the reverse sides of the three petrified palm roots seen in the previous image. They are from the late Miocene Dove Spring Formation of the Ricardo Group, collected in Last Chance Canyon long before that area was assimilated by the expanded borders of Red Rock Canyon State Park just a few years ago; today, Last Chance Canyon lies within the boundaries of Red Rock Canyon State Park--fossil collecting there is obviously forbidden, except by special permit from the state park system, a permit issued solely to qualified, trained scientists with a degree from an accredited university whose research can be verified by independent investigators. The species of palm from which the specimens came is called scientically, Palmoxylon mohavensis--from top to bottom, the petrified palm roots are 75mm, 49mm and 70mm, respectively, in actual length. |
