Erixanium sentum
No picture of Erixanium sentum 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 Erixanium sentum, or no answer at all. This entry cannot say which.

Time the record covers
At least 7.3 million years on record.
The record covers at least 494.2 Mya to 486.85 Mya. No occurrence read is dated outside 497 Mya to 484.3 Mya.
5 occurrences of Erixanium sentum 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
5 occurrences- Cambrian80%
- Ordovician20%
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 1 site for Erixanium sentum, 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.

3 references- The Upper Cambrian of the Chopko River section, Norilsk region, northwestern Siberian Platform: stratigraphy and trilobites2
- New polymerid trilobites and the first record of Erixanium from Upper Cambrian in western Hunan, China2

Each of the 5 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.
