Archaeagnostus
No picture of Archaeagnostus was found. Wikidata and iDigBio were searched and had none. Wikipedia and 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 Archaeagnostus, or no answer at all. This entry cannot say which.

Time the record covers
At least 1.5 million years on record.
The record covers at least 509.7 Mya to 508.2 Mya. No occurrence read is dated outside 515.3 Mya to 504.5 Mya.
4 occurrences of Archaeagnostus 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
4 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.

The Paleobiology Database records 4 sites for Archaeagnostus, and this reads all of them. The number is how many of those sites it was catalogued from too.
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.
Entered from
2 references- Revision of the Cambrian Agnostina (Trilobita?) from Russia3
- Latest Early Cambrian small shelly fossils, trilobites and Hatch Hill dysaerobic interval on the Québec contental slope1
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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
