Polinices (Euspira) nuciformis

Polinices nuciformis (Gabb, 1864), a relative of Polinices (Euspira) nuciformis — not Polinices (Euspira) nuciformis itself

Not Polinices (Euspira) nuciformis. This is Polinices nuciformis (Gabb, 1864), a relative — both are Naticidae.

Time the record covers

At least 27 million years on record.

The record covers at least 61.66 Mya to 33.9 Mya. No occurrence read is dated outside 66 Mya to 27.3 Mya.

71 occurrences of Polinices (Euspira) nuciformis on record, most of them in the Eocene. 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

71 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.

793 taxa

The Paleobiology Database records 67 sites for Polinices (Euspira) nuciformis, 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

24 references

Each of the 71 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. 12 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.
