Patella

Patella is a genus of herbivorous marine sea snails, commonly known as limpets, in the family Patellidae within the class Gastropoda. Primarily a marine group of prosobranch gastropods, they typically live on tidal shores in non-tropical climates. As limpets in the family Patellidae, they are a sister group to the other three accepted genera: Cymbula, Helcion, and Scutellastra. Members of the genus Patella are characterized by a cup-shaped shell and gills, and move by means of muscular waves along their

210 occurrences of Patella on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. 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

210 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.

2,694 taxa

The Paleobiology Database records 91 sites for Patella, and this reads all 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

82 references

Each of the 210 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. 70 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.
