Perisphinctes (Subdiscosphinctes)

Perisphinctes lucingae (Favre, 1875), a relative of Perisphinctes (Subdiscosphinctes) — not Perisphinctes (Subdiscosphinctes) itself

Not Perisphinctes (Subdiscosphinctes). This is Perisphinctes lucingae (Favre, 1875), a relative — both are Perisphinctidae.

Time the record covers

At most 4.2 million years on record.

Every occurrence read is dated to somewhere between 159 Mya and 154.8 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

8 occurrences of Perisphinctes (Subdiscosphinctes) on record, most of them in the Late Jurassic. 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

8 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.

64 taxa

The Paleobiology Database records 8 sites for Perisphinctes (Subdiscosphinctes), 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.

Entered from

6 references

Each of the 8 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. 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.
