Perisphinctes

Searched as Perisphinctes (Perisphinctes) panthieri polonicus. The Paleobiology Database treats Perisphinctes as the accepted name.

Perisphinctes is an extinct genus of ammonite cephalopod. They lived during the Middle to Late Jurassic epochs and serve as an index fossil for that time period. The species P. boweni was named after the English chemist and geologist E. J. Bowen (1898–1980).

Time the record covers

At most 1.1 million years on record.

The one occurrence read is dated to somewhere between 159 Mya and 157.9 Mya, which is a dating window rather than a span.

1 occurrence of Perisphinctes 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

1 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.

The Paleobiology Database records 210 sites for Perisphinctes, 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.
