Time the record covers
At least 193 million years on record.
The record covers at least 330.3 Mya to 137.05 Mya. No occurrence read is dated outside 339.9 Mya to 132.6 Mya.
376 occurrences of Pseudomonotis 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
376 occurrences- Carboniferous8%
- Permian61%
- Early Triassic11%
- Middle Triassic2%
- Late Triassic5%
- Early Jurassic5%
- Middle Jurassicunder 1%
- Late Jurassic7%
- Early Cretaceousunder 1%
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 339 sites for Pseudomonotis, 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.

Each of the 376 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. 99 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.
