Yoldia (Kalayoldia) supramontereyensis
Not Yoldia (Kalayoldia) supramontereyensis. This is Yoldia supramontereyensis (Arnold, 1908), a relative — both are Yoldiidae.

Time the record covers
At least 20 million years on record.
The record covers at least 23.04 Mya to 2.58 Mya. No occurrence read is dated outside 27.3 Mya to 1.8 Mya.
11 occurrences of Yoldia (Kalayoldia) supramontereyensis on record. 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
11 occurrences- Oligocene18%
- Miocene9%
- Pleistocene73%
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 Yoldia (Kalayoldia) supramontereyensis, 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.

Each of the 11 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
