Paleonet: Online graptolite databases

Hi Mike,

That's a very interesting summary!

You might be interested in adding some more information to the entries, such
as the geographic scope of the database and the nature of the data records.

It looks like most of the counts in your list are of specimen records and
(as you've noted) one is for the number of distinct localities including
graptolites.

Meanwhile, the counts for the PaleoDB are of fossil occurrences. That is,
each record shows that a species is present in an individual collection. A
single data record therefore might equate to an individual specimen but also
could pertain to multiple specimens of the same species from the same place.
We do store one-record-per-specimen data, but they're housed in other tables
(one that includes type specimen info and another that tracks measured
specimens).

I'm sorry if this distinction wasn't made clear, and I hope this information
proves to be helpful.

Cheers,
