Crotalocrinus sp.
No picture of Crotalocrinus sp. was found. Wikidata was searched and had none. iDigBio and GBIF were not searched: the Paleobiology Database does not place Crotalocrinus sp. firmly enough to tell it from something else bearing the same name, and a search on the name alone returns whichever of them was photographed. Wikipedia and Smithsonian Open Access did not answer, so this is what the others held rather than everything there is.
Time the record covers
At least 13 million years on record.
The record covers at least 438.6 Mya to 425 Mya. No occurrence read is dated outside 443.1 Mya to 422.7 Mya.
7 occurrences of Crotalocrinus sp. on record, most of them in the Silurian. 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
7 occurrences- Silurian100%
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 7 sites for Crotalocrinus sp., 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.
