Professional archeologists tend, it seems to lean toward nature when it comes to artifacts like “turtle” rock. So of course, this artifact was no doubt shaped by nature and time–but if it is man made, -its obviously a turtle. (And no ones saying it isn’t :0) ).

Maybe there’s something to the Morrow turtle rock after all.

A local archeologist dismissed Dirk Morgan’s find as just an odd sandstone boulder probably shaped by nature.

But, Eric Law, a geologist and associate professor at Muskingum College in New Concord, Ohio, said he’s pretty confident someone carved the rock that resembles the head of a turtle.

How did he come to that conclusion after examining the figure for two hours Wednesday?

“The most significant (feature) is something I interpreted as tool marks…They are shown at a well-protected location and are not easily destroyed by weathering or erosion processes,” Law said Friday.

Simply put, he looked far back into the mouth.

• In April, an archaeologist was skeptical.

Law’s conclusion is exciting news for Morgan, who unearthed the rock in his yard near the Little Miami River in April.

“We now know what we have is an artifact without a doubt…a relic,” he said.

Morgan, who runs a canoe livery, is convinced that the 220-pound rock was left behind by American Indians who once inhabited the area.

But, Law can’t say when the tool marks were made or by whom. That’s for an archeologist to figure out, he said.

His job, as a geologist and specialist in petrology – the branch of science that deals with the composition of rocks — was to find evidence that the rock was altered by something other than nature.

Whatever the case, Morgan’s find has sparked curiosity among professionals and amateurs who study rocks.

Law said he may present a paper on the turtle rock in October at the annual meeting of the Geological Society of America in Portland, Oregon.

“This thing is just so damn big and obvious. You look at it and immediately it says ‘animal head,’” said Alan Day, a retired engineering consultant in Cambridge, Ohio, who considers himself an amateur archeologist.

Day spends much of his retirement studying the many artifacts he’s found on his hilltop property since 1987.

He has featured information about Morgan’s turtle rock on his Web site, Day said he has heard from people all over the United States and Europe who have found similar but smaller artifacts.

“The bottom line is that people thousands of years ago were constantly carving very simple images into rocks,” Day said.
