Ever Heard of Lithophones?

image from encrypted-tbn0.gstatic.comSome time ago, and during a period of many years, a few archaeologists and various amateur collectors retrieved a number of oblong stone artifacts from the area around and including the Great Sand Dunes National Park in south-central Colorado. Eventually, many of the stones were given to the museum at Great Sand Dunes National Park where they remain stored today. [Photo of Great Sand Dunes artifacts via Archaeology Podcast Network.]

It was not especially unreasonable for archaeologists to first assume that they were an assortment of human-made manos (grinding stones) or some other kind of tool. However, they all seemed unusually large (up to two feet long) and heavy (up to ten pounds), with none of the typical wear patterns of manos. Archaeologist Marilyn Martorano spent over a decade working on the puzzle of what the stones may have been used for, if they were not manos. She recently happened upon an online video of a Paris museum's collection of similar stones that had been recovered in places as diverse as Africa, New England, Hawai'i, and New Mexico. The video demonstrated that these artifacts were not grinding stones at all, but musical percussion instruments - lithophones. (Click on that link to the video above, to hear the stones for yourself. Recommended!)

One of the Great Sand Dunes lithophones was dated to 5,000 years old, but archaeologists cannot determine the ages of the rest and there is no evidence to indicate who made them. In late 2018, Dr. Martorano added, “...Where did they get the rock to make these? And how old are they? We really don’t know a lot about that because many of these were picked up by collectors.”

Once again, people: for the sake of all of us having the chance to learn much more about our collective past, if you come across an artifact like this or of any other kind, leave it where it is and let scientists study them as-is.
