Elimia
Elimia is a genus of freshwater snails in the family Pleuroceridae. Species of the genus are aquatic gastropod mollusks that have an operculum. Various species are found in creeks throughout much of the eastern and central United States and the Great Lakes region of Canada. Fossils have been found across the whole of the North American continent, including from the Paleocene of Mexico and the Eocene of California. They were formerly included in the genus Goniobasis, together with the western Juga species.

Time the record covers
At least 85 million years on record.
The record covers at least 85.7 Mya to 11.7 ka. No occurrence read is dated outside 89.8 Mya to 0 Mya.
14 occurrences of Elimia 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
14 occurrences- Late Cretaceous14%
- Paleocene21%
- Eocene50%
- Oligocene7%
- Holocene7%
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.

The Paleobiology Database records 11 sites for Elimia, 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.

Each of the 14 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. 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.
