Note: Object Description

Holding three rods that extend up and terminate in a double backed ring. Two suspension loops on back at top of heads

Note: Condition Review
Fragmentary with many breaks and cracks. Interior appears almost completely black and mineralized. Edges are crumbling. Three small fragments are preserved separately in a polyethylene bag. There is no green corrosion present, which may indicate chemical cleaning. There are also surface areas that appear more coppery, perhaps due to overcleaning. Dendritic pattern on surface may also be from chemical cleaning
Note: Follow-up Notes
Special. Extremely mineralized and brittle but interesting dendritic features visible on surface and at break edge. If it would be at all possible to do ESEM-EDS to determine the composition of the dendrites at break, that would be interesting
Note: Analysis Recommendations
