Pitar
Searched as Pitar uvasana duprei. The Paleobiology Database treats Pitar as the accepted name.
Pitar is a genus of saltwater clams, marine bivalve molluscs in the subfamily Callocardiinae of the family Veneridae, the Venus clams. The genus contains over 60 species.

Time the record covers
At most 15 million years on record.
Every occurrence read is dated to somewhere between 56 Mya and 41.03 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
10 occurrences of Pitar 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
10 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 801 sites for Pitar, 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.
