Omphalotrochidae

Omphalotrochidae is an extinct taxonomic family of Paleozoic molluscs (gastropods?) with anisostrophically coiled shells of uncertain position (Gastropoda?).

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

At least 158 million years on record.

The record covers at least 413.02 Mya to 254.14 Mya. No occurrence read is dated outside 419.62 Mya to 251.902 Mya.

223 occurrences of Omphalotrochidae on record, most of them in the Permian. 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

223 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.

1,954 taxa

The Paleobiology Database records 197 sites for Omphalotrochidae, 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.

Entered from

60 references

Each of the 223 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. 48 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.
