Myadesma pacifica
No picture of Myadesma pacifica was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Myadesma pacifica, or no answer at all. This entry cannot say which.

Time the record covers
At least 17 million years on record.
The record covers at least 33.9 Mya to 15.98 Mya. No occurrence read is dated outside 37.71 Mya to 11.63 Mya.
3 occurrences of Myadesma pacifica 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
3 occurrencesThese 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 Myadesma pacifica, 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
2 references- Tumey Sandstone (Tertiary), Fresno County, California2
- California Late Cretaceous donaciform bivalves1
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.
