Pectinida

Pectinida is a taxonomic order of saltwater and brackish clams, bivalve molluscs, commonly known as scallops and their allies. They evolved somewhere in the late Middle Ordovician epoch. The order was first defined and published by John Edward Gray in 1854.

Time the record covers

At least 432 million years on record.

The record covers at least 432.9 Mya to 11.7 ka. No occurrence read is dated outside 443.1 Mya to 0 Mya.

12,000+ occurrences of Pectinida on record. The Paleobiology Database records this as a living group. 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

12,000 occurrences read

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. The read hit its cap, so every figure above is a floor and the shares are of the occurrences read. More on what this infers.

The named rock units Pectinida has been recovered from, largest first. Drawn where the rock is now, not where it formed. The read hit its cap, so each count is a floor. 894 further formations hold fewer occurrences each and are not listed. 3,453 occurrences have no formation on record, which is common for older literature.

Found in the same rock

1,555 taxa

The Paleobiology Database records at least 753 sites for Pectinida, and this reads 240 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

at least 708 references

Each of the 12,000 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. That read hit its cap, so each count is a floor. 696 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.
