Ancyrochitina
No picture of Ancyrochitina was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was not searched: the Paleobiology Database does not place Ancyrochitina 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.
On record
Recorded, not inferred- Sits inside
- RhizopodeaPBDB
Time the record covers
At least 25 million years on record.
The record covers at least 445.2 Mya to 419.62 Mya. No occurrence read is dated outside 452.8 Mya to 410.62 Mya.
124 occurrences of Ancyrochitina on record, most of them in the Silurian. 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
124 occurrences- Ordovician10%
- Silurian88%
- Devonian2%
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 45 sites for Ancyrochitina, 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 124 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. 2 further references are not listed. 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.
