Polygonella
No picture of Polygonella was found. iDigBio was searched and had none. Wikipedia and Wikidata have a picture filed under this name, but nothing tied it to Polygonella itself, so it was not used. 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 Polygonella, or no answer at all. This entry cannot say which.

Time the record covers
At least 87 million years on record.
The record covers at least 143.1 Mya to 56 Mya. No occurrence read is dated outside 161.5 Mya to 33.9 Mya.
4 occurrences of Polygonella 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
4 occurrences- Late Jurassic25%
- Paleocene25%
- Eocene50%
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 2 sites for Polygonella, 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
3 references- Paleogene calcium algae fossils and sedimentary environment in Yadongduna area, southern Tibet2
- Coralline Algae from the Cretaceous and Early Tertiary of Greece1
- New Calcareous Algae from the Arabian Peninsula1
Each of the 4 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.
