Antiquatonia
Antiquatonia is an extinct genus of brachiopod belonging to the order Productida and family Productidae. Specimens have been found in Carboniferous beds across many continents, suggesting the genus had a cosmopolitan distribution. Species level taxonomy of Antiquatonia is in need of revision.

Time the record covers
At least 86 million years on record.
The record covers at least 346.7 Mya to 259.857 Mya. No occurrence read is dated outside 358.86 Mya to 254.14 Mya.
269 occurrences of Antiquatonia on record, most of them in the Carboniferous. 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
269 occurrences- Carboniferous88%
- Permian12%
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 225 sites for Antiquatonia, 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.
