Some of the columns from the latest map seem to be implausibly under-sampled. This includes some in the middle of Hudson Bay and Canada. A lot of these seem to be lakes or near lakes. Are we getting a strange signal from lake cores?
Let's do a sanity check on the sentences, pbdb, and original documents to get a feel for what's going on here. There may be something messed up with the new cleaning procedures workflow.
Checks
[ ] Look at GDD sentences to see if the sentences are correct
[ ] Look in PBDB to make sure those formations are truly marked as unfossiliferous
[ ] Examine the actual document to see if, beyond the context of the sentence, these units are fossiliferous.
