Time the record covers
At least 73 million years on record.
The record covers at least 464.3 Mya to 390.5 Mya. No occurrence read is dated outside 471.3 Mya to 382.31 Mya.
46 occurrences of Harpes on record, most of them in the Devonian. 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
46 occurrences- Ordovician17%
- Silurian4%
- Devonian78%
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 Harpes has been recovered from, largest first. Drawn where the rock is now, not where it formed. One further formation holds fewer occurrences and is not listed. 8 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 46 sites for Harpes, 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 46 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. 19 further references are not listed. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
