Procolophonoidea
Procolophonoidea is an extinct superfamily of procolophonian parareptiles. Members were characteristically small, stocky, and lizard-like in appearance. Fossils have been found worldwide from many continents including Antarctica. The first members appeared during the Late Permian in the Karoo Basin of South Africa.

Time the record covers
At least 51 million years on record.
The record covers at least 256.8 Mya to 205.7 Mya. No occurrence read is dated outside 298.9 Mya to 174.7 Mya.
177 occurrences of Procolophonoidea on record, most of them in the Early Triassic. 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
177 occurrences- Permian10%
- Early Triassic47%
- Middle Triassic22%
- Late Triassic21%
- Early Jurassicunder 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 107 sites for Procolophonoidea, 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 177 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. 92 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.
