Time the record covers
At most 4.3 million years on record.
Every occurrence read is dated to somewhere between 27.3 Mya and 23.04 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
3 occurrences of Yoldia olympiana on record, most of them in the Oligocene. 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
3 occurrences- Oligocene100%
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 3 sites for Yoldia olympiana, 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.
Entered from
3 references- Megafaunal zones of the Oligocene of northwestern Washington1
- Paleontology of the Marine Tertiary formations of Oregon and Washington1
- Pelecypoda from the Marine Oligocene of Western North America1
Each of the 3 occurrences 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.
