not sure what’s going on here or if the weirdness originates in iNaturalist or GBIF, but i wanted to make a note of it here.
i was looking at iNaturalist metrics over at GBIF (https://www.gbif.org/dataset/50c9509d-22c7-4a22-a47d-8c48425ef4a7/metrics), and the Occurrences by Year graph at the end of the page seems to start in year 1601:
Sure enough, it looks like there are 6 occurrences that have been loaded with a date of January 1, 1601:
looking at the original iNaturalist record for one of these records, it looks like the submitted and observed dates are both in 2020.
