Time the record covers
At least 240 million years on record.
The record covers at least 473.8 Mya to 233.6 Mya. No occurrence read is dated outside 477.1 Mya to 174.7 Mya.
1,647 occurrences of Grammysioidea on record, most of them in the Permian. 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
1,647 occurrences- Ordovician4%
- Silurian4%
- Devonian31%
- Carboniferous20%
- Permian40%
- Middle Triassicunder 1%
- Late Triassicunder 1%
- Early Jurassicunder 1%
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 1,194 sites for Grammysioidea, and this reads 240 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 1,647 occurrences read was entered from one of these publications, ordered by how many each accounts for.
