Rhaptagnostus cyclopygeformis
No picture of Rhaptagnostus cyclopygeformis 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 Rhaptagnostus cyclopygeformis, or no answer at all. This entry cannot say which.

Time the record covers
At least 1.3 million years on record.
The record covers at least 492.8 Mya to 491.5 Mya. No occurrence read is dated outside 497 Mya to 486.85 Mya.
39 occurrences of Rhaptagnostus cyclopygeformis on record, most of them in the Cambrian. 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
39 occurrences- Cambrian100%
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.

Each of the 39 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.
