Palaeozygopleuridae

Palaeozygopleuridae is an extinct taxonomic family of fossil sea snails, marine gastropod molluscs.

Loxonema hamiltoniae (Hall, 1859), a relative of Palaeozygopleuridae — not Palaeozygopleuridae itself

Not Palaeozygopleuridae. This is Loxonema hamiltoniae (Hall, 1859), a relative — both are Palaeozygopleuridae.

Time the record covers

At least 158 million years on record.

The record covers at least 422.7 Mya to 264.28 Mya. No occurrence read is dated outside 443.1 Mya to 259.857 Mya.

269 occurrences of Palaeozygopleuridae on record, most of them in the Devonian. 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

269 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.

2,499 taxa

The Paleobiology Database records 197 sites for Palaeozygopleuridae, 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.

99 references

Each of the 269 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. 87 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.
