Terebridae
The Terebridae, commonly referred to as auger shells or auger snails, is a family of predatory marine gastropods in the superfamily Conoidea. They have extremely high-spired shells with numerous whorls; their common name refers to the resemblance of their shells to rock-drill bit. More than 400 species are recently known worldwide.

Time the record covers
At least 61 million years on record.
The record covers at least 61.66 Mya to 11.7 ka. No occurrence read is dated outside 66 Mya to 0 Mya.
1,728 occurrences of Terebridae on record, most of them in the Miocene. 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
1,728 occurrencesThese 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 640 sites for Terebridae, 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.

Each of the 1,728 occurrences read was entered from one of these publications, ordered by how many each accounts for.
