Marginifera
Searched as Marginifera pusilla mapingensis. The Paleobiology Database treats Marginifera as the accepted name.
Marginifera is an extinct genus of brachiopod belonging to the order Productida. Specimens have been found in Carboniferous to Triassic beds in Asia, Europe, Madagascar, and North America.

Time the record covers
At most 11 million years on record.
Every occurrence read is dated to somewhere between 303.7 Mya and 293.52 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.
6 occurrences of Marginifera on record, most of them in the Permian. 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
6 occurrences- Carboniferous17%
- Permian83%
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 602 sites for Marginifera, and this reads 240 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.
