Pseudoholaster
No picture of Pseudoholaster 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 Pseudoholaster, or no answer at all. This entry cannot say which.

Time the record covers
At least 27 million years on record.
The record covers at least 113.2 Mya to 85.7 Mya. No occurrence read is dated outside 121.4 Mya to 83.6 Mya.
5 occurrences of Pseudoholaster on record, most of them in the Late Cretaceous. 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.

The Paleobiology Database records 1 site for Pseudoholaster, 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- Late Cretaceous macrofossils from Sinai, Egypt3
- Santonian (Late Cretaceous) echinoids from the Santander area (northern Cantabria, Spain)1
- Aptian-Cenomanian Echinoids from Egypt1
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. 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.
