Physeter
Searched as Physeter macrocephalus catodon. The Paleobiology Database treats Physeter as the accepted name.
Physeter is a genus of toothed whales. There is only one living species in this genus: the sperm whale. Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus from the Pliocene of France, and Physeter vetus from the Quaternary of the U.S. state of Georgia. Physeter vetus is very likely an invalid species, as the few teeth that were used to identify this species appear to be identical to those of another toothed whale, Orycterocetus quadratidens.

Time the record covers
At most 118 thousand years on record.
The one occurrence read is dated to somewhere between 129 ka and 11.7 ka, which is a dating window rather than a span.
1 occurrence of Physeter on record, most of them in the Pleistocene. 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 occurrences- Pleistocene100%
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 73 sites for Physeter, 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.
