Scaphokogia
Scaphokogia is an extinct genus of pygmy sperm whales that lived off the coasts of Mexico and Peru, South America during the Late Miocene to Late Pliocene. Two species have currently been described: the type species S. cochlearis and S. totajpe. It is estimated to have reached up to 2.2–2.8 metres (7.2–9.2 ft) in total length. Fossils of Scaphokogia have been found in the Tirabuzon Formation of Baja California and the Pisco Formation of Peru. Scaphokogia existed about 5 million years ago, and were relatively rare animals.
No picture of Scaphokogia was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Scaphokogia, or no answer at all. This entry cannot say which.

Time the record covers
At least 1.9 million years on record.
The record covers at least 7.246 Mya to 5.333 Mya. No occurrence read is dated outside 11.63 Mya to 2.58 Mya.
4 occurrences of Scaphokogia on record, most of them in the Miocene. 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
4 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 4 sites for Scaphokogia, 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.
