Calliostoma
Searched as Calliostoma nordenskjoldi. The Paleobiology Database treats Calliostoma as the accepted name.
Calliostoma is a genus of small to medium-sized sea snails with gills and an operculum, marine gastropod molluscs within the family Calliostomatidae, the Calliostoma top snails. Previously this genus was placed within the family Trochidae. Calliostoma is the type genus of the family Calliostomatidae.

Time the record covers
At most 12 thousand years on record.
The one occurrence read is dated to somewhere between 11.7 ka and 0 Mya, which is a dating window rather than a span.
1 occurrence of Calliostoma on record, most of them in the Holocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
1 occurrences- Holocene100%
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 385 sites for Calliostoma, and this reads 240 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
