Hexaprotodon
Searched as Hexaprotodon sinhaleyus. The Paleobiology Database treats Hexaprotodon as the accepted name.
Hexaprotodon is an extinct genus of hippopotamid. The genus name Hexaprotodon comes from Ancient Greek ἑξα- (hexa-), meaning "six", πρῶτος (prôtos), meaning "first", and ὀδούς (odoús), meaning "tooth", therefore, "six front-teeth" as some of the fossil forms have three pairs of incisors. The pygmy hippopotamus was historically placed in the genus, but today is generally placed in its own genus. The core unambiguous Asian members of the genus ranged from the Indian subcontinent to Southeast Asia, and are thought to have had an aquatic ecology similar to that of the living common hippopotamus. Other species have been attributed to the genus from Africa and Europe, though it is unclear whether they are closely related to the Asian members of the genus. The last members of the genus became extinct during the Late Pleistocene, perhaps as recently as 15,000 years ago.

Time the record covers
At most 2.6 million years on record.
The one occurrence read is dated to somewhere between 2.58 Mya and 11.7 ka, which is a dating window rather than a span.
1 occurrence of Hexaprotodon on record, most of them in the Pleistocene. 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 112 sites for Hexaprotodon, 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.
