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

Time the record covers
At most 16 million years on record.
Every occurrence read is dated to somewhere between 458.2 Mya and 443.1 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
2 occurrences of Cliefdenella alaskaensis on record, most of them in the Ordovician. 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
2 occurrences- Ordovician100%
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 1 site for Cliefdenella alaskaensis, 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 references- Ordovician sponges from west-central and east-central Alaska and western Yukon Territory, Canada1
- Ordovician sponges from the Montgomery Limestone, Taylorsville area, northern Sierra Nevada, California, USA1
Each of the 2 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
