Crassostrea

Searched as Crassostrea vaughani insularis. The Paleobiology Database treats Crassostrea as the accepted name.

Crassostrea is a genus of true oysters containing some of the most important oysters used for food.

Time the record covers

At most 7.1 million years on record.

The one occurrence read is dated to somewhere between 23.04 Mya and 15.98 Mya, which is a dating window rather than a span.

1 occurrence of Crassostrea on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

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.

3,352 taxa

The Paleobiology Database records 468 sites for Crassostrea, 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.

Entered from

1 reference

Each of the 1 occurrence read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
