Deacybele
Deacybele is a genus of trilobites in the order Phacopida, that existed during the upper Ordovician in what is now Ireland. It was described by Whittington in 1965, and the type species is Deacybele arenosa, which was originally described under the genus Calymene by McCoy in 1846. The type locality was the Avoca Formation.
No picture of Deacybele was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Deacybele, or no answer at all. This entry cannot say which.

Time the record covers
At least 6.7 million years on record.
The record covers at least 457.2 Mya to 450.5 Mya. No occurrence read is dated outside 458.2 Mya to 449.2 Mya.
25 occurrences of Deacybele on record, most of them in the Ordovician. 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
25 occurrences- Ordovician100%
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 25 sites for Deacybele, 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 25 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. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
