Time the record covers
At least 5.5 million years on record.
The record covers at least 393.47 Mya to 387.95 Mya. No occurrence read is dated outside 410.62 Mya to 382.31 Mya.
4 occurrences of Corocrinus 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
4 occurrences- Devonian100%
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 4 sites for Corocrinus, 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.

4 references- Early Devonian echinoderms from South Africa1
- Strata and megafossils of the Middle Devonian Silica Formation1
- A new Brittle-star from the Middle Devonian Arkona Shale of Ontario1
- Two new crinoids of the family Periechocrinitidae from the Middle Devonian Thunder Bay Limestone of Michigan1
Each of the 4 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 the Paleobiology Database's own record for the work.
