- Laboratory comment:
- Radiocarbon measurements are corrected for C13 and are ?numerically equal to delta but are expressed as per cent ?deviation from the count rate of 0.95 NBS oxalic acid, rather ?than as per mill. The deltaC13 mesurements with refernce to ?Chicago PDB standard were carried out by M.Yzuel in the Inst. of ?Geophysic, UCLA. Shells collected and submited by R. E.Taylor and ?R. Berger (1967), UCLA. Uncorected delta C14 = +1.01+-0.45. 0
