Neithea

Neithea is an extinct genus of bivalve molluscs that lived from the Early Jurassic to the early Paleocene, with a worldwide distribution. Neithia sp. are inequivalve. That means that the two valves are not the same shape, the right valve being strongly concave and the left valve being flattened or concave. Sculpture consist of alternating strong and weaker radiating ribs.

Time the record covers

At least 71 million years on record.

The record covers at least 137.05 Mya to 66 Mya. No occurrence read is dated outside 161.5 Mya to 61.66 Mya.

494 occurrences of Neithea on record, most of them in the Late Cretaceous. 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

494 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.

2,194 taxa

The Paleobiology Database records 359 sites for Neithea, and this reads 240 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

128 references

Each of the 494 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. 116 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.
