'''Problem:''' The date the specimen was [https://dwc.tdwg.org/terms/#dwc:dateIdentified identified], collected (often designated using the [https://dwc.tdwg.org/terms/#dwc:eventDate eventDate] field), or [https://dwc.tdwg.org/terms/#dwc:georeferencedDate georeferenced] is in the future.

=== Date is Suspiciously Old ===
'''Problem:''' The date the specimen was [https://dwc.tdwg.org/terms/#dwc:dateIdentified identified], collected (often designated using the [https://dwc.tdwg.org/terms/#dwc:eventDate eventDate] field), or [https://dwc.tdwg.org/terms/#dwc:georeferencedDate georeferenced] is outside the expected historical date range. The expected date range depends on the institution, but it is unlikely that most collections have specimens with dates prior to 1600.
