Microcallista (Costacallista) conradiana meganosensis

Not Microcallista (Costacallista) conradiana meganosensis. This is Microcallista conradiana (Gabb, 1864), a relative — both are Veneridae.

Time the record covers
At most 8 million years on record.
Every occurrence read is dated to somewhere between 56 Mya and 48.07 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
8 occurrences of Microcallista (Costacallista) conradiana meganosensis on record, most of them in the Eocene. 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
8 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 8 sites for Microcallista (Costacallista) conradiana meganosensis, 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.
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.
