Chelonariidae
Chelonariidae or turtle beetles is a family of beetles in the superfamily Byrrhoidea. It was described by Blanchard in 1845. There are 3 genera with around 300 described species. Little is known of their ecology, though it seems they are associated with the roots of orchids and the nests of ants and termites. Their exoskeletons are heavily sclerotised and their limbs can be effectively retracted into their bodies due to the presence of socket-like cavities. Adult specimens have seed-shaped bodies that are typically colored brown or black with lighter patches.

Time the record covers
At least 100 million years on record.
The record covers at least 121.4 Mya to 20.45 Mya. No occurrence read is dated outside 125.77 Mya to 13.82 Mya.
5 occurrences of Chelonariidae on record, most of them in the Eocene. 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
5 occurrences- Early Cretaceous20%
- Eocene60%
- Miocene20%
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 Chelonariidae, 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 5 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. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
