Time the record covers

At least 41 million years on record.

The record covers at least 113.2 Mya to 72.2 Mya. No occurrence read is dated outside 121.4 Mya to 66 Mya.

220 occurrences of Pterotrigonia (Scabrotrigonia) on record, most of them in the Late Cretaceous. 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

220 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 named rock units Pterotrigonia (Scabrotrigonia) has been recovered from, largest first. Drawn where the rock is now, not where it formed. 16 further formations hold fewer occurrences each and are not listed. 48 occurrences have no formation on record, which is common for older literature.

Found in the same rock

1,015 taxa

The Paleobiology Database records 164 sites for Pterotrigonia (Scabrotrigonia), and this reads all of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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

29 references

Each of the 220 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. 17 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.
