|---|---|
| 1 | Indication that the date is approximate, with unspecified or unquantifiable errors.Ca. |
| 2 | (For radiometric dates only). Oldest possible age of sample, often representing open ended dating where only one extreme limit is known. Occasionally used as part of a >< pair to define approximate age range. |
| 3 | (For radiometric dates only). Youngest possible age of sample, often representing open ended dating where only one extreme limit is known. Occasionally used as part of a >< pair to define approximate age range. |
| 4 | Oldest possible age of sample, usually part of a from-to pair, but could be used to represent open ended dating. |
| 5 | Youngest possible age of sample, usually part of a from-to pair, but could be used to represent open ended dating. |
| 6 | Approximate oldest possible age of sample, usually part of a from-to pair, but could be used to represent open ended dating. |
| 7 | Approximate youngest possible age of sample, usually part of a from-to pair, but could be used to represent open ended dating. |
| 8 | Dating is disputable. |
