Time the record covers
At least 20 million years on record.
The record covers at least 20.45 Mya to 11.7 ka. No occurrence read is dated outside 23.04 Mya to 0 Mya.
24 occurrences of Morula 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
24 occurrences- Miocene25%
- Pliocene21%
- Pleistocene50%
- Holocene4%
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 12 sites for Morula, 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 24 occurrences read was entered from one of these publications, ordered by how many each accounts for.
