Periporopollenites demarcatus
No picture of Periporopollenites demarcatus was found. Wikidata and iDigBio were searched and had none. Wikipedia and 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 Periporopollenites demarcatus, or no answer at all. This entry cannot say which.

- PeriporopollenitesPBDB
- Diet
- "photoautotroph"PBDB, for Streptophyta
Time the record covers
At least 50 million years on record.
The record covers at least 66 Mya to 15.98 Mya. No occurrence read is dated outside 72.2 Mya to 11.63 Mya.
23 occurrences of Periporopollenites demarcatus on record, most of them in the Paleocene. 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
23 occurrences- Late Cretaceous13%
- Paleocene35%
- Eocene17%
- Oligocene18%
- Miocene17%
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 22 sites for Periporopollenites demarcatus, 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 23 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.
