Ecphora
Ecphora is a genus of extinct predatory ocenebrinid murexes indigenous to the North American Eastern Seaboard from Miocene until their extinction during the Pliocene. The common name for this genus and a group of related genera is "ecphora"(s).

Time the record covers
At least 68 million years on record.
The record covers at least 72.2 Mya to 3.6 Mya. No occurrence read is dated outside 83.6 Mya to 2.58 Mya.
129 occurrences of Ecphora on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
129 occurrences- Late Cretaceous11%
- Oligocene5%
- Miocene60%
- Pliocene24%
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 108 sites for Ecphora, 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 129 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. 19 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.
