Description: I have noticed that many of the records from BMSM Bailey-Matthews National Shell Museum are reported as occurring in 1758. This, unfortunately, is when those taxa were first published by Linnaeus, not when they were collected. I verified this for a few occurrences from the BMSM's actual online collections database.
The problem is that their database has a separate field for the original author's year simply called "year". I can imagine this has caused some serious confusion.
I can't say what other data suppliers may also present this problem, but I thought it should certainly be mentioned.

For all occurrences I have compared the year collected with the year the name was published.
There are 1.741.933 occurrences that were collected after 1700 and more than 5 years before the name was published.
Attached is a file occ_before_species_published.csv with results grouped by dataset.
Example records from the dataset with the largest number of suspicous records:
