Acanthochitina

No picture of Acanthochitina was found. Wikipedia, Wikidata and iDigBio were searched and had none. GBIF was not searched: the Paleobiology Database does not place Acanthochitina 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. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is.

Time the record covers

At most 400 thousand years on record.

The one occurrence read is dated to somewhere between 449.9 Mya and 449.5 Mya, which is a dating window rather than a span.

1 occurrence of Acanthochitina 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

1 occurrences

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.

35 taxa

The Paleobiology Database records 1 site for Acanthochitina, 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.

Entered from

1 reference

Each of the 1 occurrence 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.
