Time the record covers
At least 49 million years on record.
The record covers at least 52 Mya to 2.58 Mya. No occurrence read is dated outside 56 Mya to 774 ka.
11 occurrences of Lissotesta on record. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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
11 occurrences- Eocene9%
- Miocene36%
- Pleistocene55%
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 Lissotesta has been recovered from, largest first. Drawn where the rock is now, not where it formed. 6 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 6 sites for Lissotesta, 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.

Each of the 11 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. Each entry links to the Paleobiology Database's own record for the work.
