Spongy bones like ball and sockets, vertebra, and the like do not tend to preserve well in harsh conditions and may not yield sufficient collagen for AMS dating.
The collagen is then dissected and inspected for rootlets.
Teeth – For human teeth, preferred samples are single complete incisor or canine. For animal teeth, the sample size depends on the animal. For small animals, please consult the lab regarding the appropriate quantity.
Antlers – Chunks, chips, and shavings are best for radiocarbon dating.
This step is usually highly destructive to the collagen but provides a clean sample for radiocarbon dating.
After a final acid wash, the collagen is dried and measured for d13C.
If your samples are already powderized, please contact us for discussion.
