An Archaeological Find
While visiting my family in southern Maryland for Thanksgiving, I had the privilege of finding something of archaeological significance (to me at least). My Mom lives along the Chesapeake Bay and we enjoy walking along the beach looking for fossil shark teeth and anything interesting. I stumbled upon something that looked similar to a shark tooth but the color was more of a tan then the dark color that shark teeth normally have. I picked it up to inspect it and it turned out to be an arrowhead made of chert. I emailed a picture to some archaeologists in Maryland and below is their replies . .

Mr. Riddile,
I think you found an authentic arrowhead, or projectile point, made from a stone called chert. Triangular points like these were used on arrows during the Late Woodland Period, between roughly 900 and 1600 A.D. Yours is probably one of two types of triangular points, called Levanna and Madison. The two types overlap somewhat in appearance, and yours falls in that overlap zone. Levanna points tend to be older than Madison points. I think your point is authentic because the surface seems to show evidence of weathering or water wear. If it was a newly-made point, the surface would be fresh, not worn. Triangular points are pretty common in Calvert County, so it is not surprising that you found one, although yours is in notably good condition, without any fractures. Also, in Calvert they are more commonly made from quartz, not chert, so yours is a little unusual in that respect also. If you have any questions, feel free to contact me. If you are interested in archaeology, you should come help us excavate a site next summer here at Jefferson Patterson Park and Museum. You will find more details about our Public Archaeology Program on our website, www.jefpat.org. Information about next year’s dig should be posted by the springtime.

Dear Mr. Riddile,
I’m happy that Ed answered your inquiry. His answer is excellent, complete, and right on the mark. I’d add that your artifact was actually manufactured to tip a bow-shot arrow. The bow and arrow didn’t make an appearance in Maryland until quite late in prehistory (perhaps as early as AD 500, certainly by AD 900). Before that the only projectile in use was a spear, usually tipped with a much larger and heavier point. I’d also add that the material from which your arrowhead was made (chert) is an “exotic” to Calvert county. It occurs naturally in areas underlain with limestone bedrock. Most likely the chert from which your arrowhead was made was transported to the middle Bay area from far to the north by the ancestral Susquehanna River long ago during the Pleistocene geologic epoch, before the Chesapeake existed. Alternatively, it may have been transported by an individual who had traveled to the source area either far to the north or west of Calvert County. Either way, it’s interesting!
Thanks for sharing your artifact with us.
