Otariidae
An eared seal, otariid, or otary, is any member of the marine mammal family Otariidae, one of three groupings of pinnipeds. They comprise 15 extant species in seven genera and are commonly known either as sea lions or fur seals, distinct from true seals (phocids) and the walrus (odobenids). Otariids are adapted to a semiaquatic lifestyle, feeding and migrating in the water, but breeding and resting on land or ice. They reside in subpolar, temperate, and equatorial waters throughout the Pacific and Southern Oceans, the southern Indian, and Atlantic Oceans. They are conspicuously absent in the north Atlantic.

Time the record covers
At least 23 million years on record.
The record covers at least 23.04 Mya to 11.7 ka. No occurrence read is dated outside 27.3 Mya to 0 Mya.
329 occurrences of Otariidae on record. 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
329 occurrences- Oligoceneunder 1%
- Miocene15%
- Pliocene11%
- Pleistocene31%
- Holocene43%
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 named rock units Otariidae has been recovered from, largest first. Drawn where the rock is now, not where it formed. 38 further formations hold fewer occurrences each and are not listed. 197 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 289 sites for Otariidae, and this reads 240 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 329 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. 132 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.
