Retaria

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

12,000+ occurrences of Retaria on record. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

12,000 occurrences read

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. The read hit its cap, so every figure above is a floor and the shares are of the occurrences read. More on what this infers.

The named rock units Retaria has been recovered from, largest first. Drawn where the rock is now, not where it formed. The read hit its cap, so each count is a floor. 34 further formations hold fewer occurrences each and are not listed. 2,055 occurrences have no formation on record, which is common for older literature.

Found in the same rock

1,327 taxa

The Paleobiology Database records at least 109 sites for Retaria, and this reads 109 of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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.

Entered from

at least 65 references

Each of the 12,000 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. That read hit its cap, so each count is a floor. 53 further references are not listed. 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 picture of Retaria was found. iDigBio was searched and had none.

Wikipedia has a picture filed under this name, but nothing tied it to Retaria itself, so it was not used.

Wikidata 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 Retaria, or no answer at all. This entry cannot say which.

Smithsonian Open Access and MorphoSource were 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.
