Semilingula arctica
Searched as Lingula arctica. The Paleobiology Database treats Semilingula arctica as the accepted name.
No picture of Semilingula arctica 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 Semilingula arctica, or no answer at all. This entry cannot say which.

Time the record covers
At least 68 million years on record.
The record covers at least 274.4 Mya to 205.7 Mya. No occurrence read is dated outside 283.3 Mya to 201.4 Mya.
7 occurrences of Semilingula arctica on record, most of them in the Permian. 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
7 occurrences- Permian86%
- Late Triassic14%
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.

Found in the same rock
1 taxonThe Paleobiology Database records 6 sites for Semilingula arctica, and this reads all of them. The number is how many of those sites it was catalogued from too.
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 referencesEach of the 7 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
