The first stones identified as Bird Effigies had

what looked like writing inscribed on them.

These were initially thought to be grave stones

written in a script most like Iberian Punic, a

phoenician related alphabet found in Spain and

Portugal that dates to 1,000 BC. Unfortunately,

no 3,000 year old artifacts have been found on

the SDM Site to support that time period.

Everything found is clearly Paleo, with maybe a

trace of Early Archaic.

Many of the "inscriptions" turned out to be

marks from agricultural machinery, commonly

called "plow marks". Some, however, are not.

Similar abstract symbols inscribed on rock

appear in Western Europe by a distantly related

culture over 15,000 years ago. That script was

used strictly for religious and ritual purposes.

Many Hundreds of roughly triangular granite

stones without inscriptions have been identified

as "Bird Effigies" because of the surface

alteration done to them by pounding, pecking

and chipping, in obvious contrast to the

normally rounded and smooth glacial finish.

These stone "Bird Effigies" range in size from

under one inch to about four feet high, though

most are under about twelve inches.

In numbers as well as mass, stone Birds are the

most prominent artifact found on the SDM Site.

Natural 'Bird' shapes are not uncommon if you

look hard enough anywhere that stones or rocks

are exposed. Most stones were found

somewhere off-site and brought here to SDM to

be modified.It is possible that 'birds' were made

of other material as well such as bone, wood, or

clay for example, and left at the funeral site

where only the stone effigies survived.

The idea and practice of making and using the

"Bird Effigy" at a funeral or to be left at the

cemetary in the far distant past evolved into

the erection of the uncounted thousands of

Megalithic standing stones that start to appear

all over the World well over 6,000 years ago.
