Time the record covers

At least 366 million years on record.

The record covers at least 393.47 Mya to 27.3 Mya. No occurrence read is dated outside 410.62 Mya to 20.45 Mya.

273 occurrences of Polidevcia 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

273 occurrences

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.

Found in the same rock

2,214 taxa

The Paleobiology Database records 241 sites for Polidevcia, 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.

Entered from

77 references

Each of the 273 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. 65 further references are not listed. Each entry links to the Paleobiology Database's own record for the work.
