Balaenopteridae
Rorquals are the largest group of baleen whales, comprising the family Balaenopteridae, which contains nine extant species in two genera. They include the largest animal ever known to have lived, the blue whale, which can reach 180 tonnes, and the fin whale, which reaches 120 tonnes ; the smallest of the group, the northern minke whale, reaches 9 tonnes.

Time the record covers
At least 15 million years on record.
The record covers at least 15.98 Mya to 11.7 ka. No occurrence read is dated outside 27.3 Mya to 0 Mya.
465 occurrences of Balaenopteridae on record, most of them in the Pliocene. 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
465 occurrences- Oligoceneunder 1%
- Miocene24%
- Pliocene37%
- Pleistocene14%
- Holocene24%
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 Balaenopteridae has been recovered from, largest first. Drawn where the rock is now, not where it formed. 87 further formations hold fewer occurrences each and are not listed. 234 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 352 sites for Balaenopteridae, 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 465 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. 196 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.
