Arca pseudonavicularis
No picture of Arca pseudonavicularis was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Arca pseudonavicularis, or no answer at all. This entry cannot say which.

Time the record covers
At least 10 million years on record.
The record covers at least 33.9 Mya to 23.04 Mya. No occurrence read is dated outside 37.71 Mya to 15.98 Mya.
5 occurrences of Arca pseudonavicularis 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
5 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.
Found in

The named rock units Arca pseudonavicularis has been recovered from, largest first. Drawn where the rock is now, not where it formed. 1 occurrence has no formation on record, which is common for older literature.

The Paleobiology Database records 3 sites for Arca pseudonavicularis, 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- Eocene bivalves and gastropods from the Pallinup Siltstone, Western Australia, with new records from the Eocene and Oligocene of southeastern Australia3

Each of the 5 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.
