Olenellus chiefensis Palmer, 1998, a relative of Olenellus (Paedeumias) chiefensis — not Olenellus (Paedeumias) chiefensis itself

Not Olenellus (Paedeumias) chiefensis. This is Olenellus chiefensis Palmer, 1998, a relative — both are Olenellidae.

Time the record covers

At most 7.8 million years on record.

Every occurrence read is dated to somewhere between 516 Mya and 508.2 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

13 occurrences of Olenellus (Paedeumias) chiefensis on record, most of them in the Cambrian. 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

13 occurrences

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.

19 taxa

The Paleobiology Database records 6 sites for Olenellus (Paedeumias) chiefensis, 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

5 references

Each of the 13 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.

No 3D scan of Olenellus (Paedeumias) chiefensis was found in MorphoSource and Sketchfab.

Smithsonian Open Access was not reached for this taxon, so this list is what the others held rather than everything there is.

This is what the site found, which is not the same as what exists.
