Barbatia
Searched as Barbatia (Barbatia) appendiculata appendiculata. The Paleobiology Database treats Barbatia as the accepted name.
Barbatia is a genus of "bearded" ark clams, marine bivalve mollusks in the family Arcidae, the ark clams.

Time the record covers
At most 3.9 million years on record.
The one occurrence read is dated to somewhere between 37.71 Mya and 33.9 Mya, which is a dating window rather than a span.
1 occurrence of Barbatia on record, most of them in the Eocene. 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- Eocene100%
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 515 sites for Barbatia, 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 referenceEach 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 the Paleobiology Database's own record for the work.
