These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 15 sites for Euaesthetinae, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
