Polyzoniida
Polyzoniida is an order of millipedes in the subterclass Colobognatha. This order contains three families and more than 70 described species. The species in this order are also known as camphor millipedes, because ozopore secretions in this order frequently have a strong camphor-like smell. Poison frogs in South America and Madagascar evidently obtain some of their poison from these millipedes.

Time the record covers
At least 73 million years on record.
The record covers at least 93.9 Mya to 20.45 Mya. No occurrence read is dated outside 100.5 Mya to 13.82 Mya.
6 occurrences of Polyzoniida on record, most of them in the Late Cretaceous. 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
6 occurrences- Late Cretaceous83%
- Miocene17%
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 5 sites for Polyzoniida, 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 6 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
