Trigoniida

Trigoniida is an order of medium-sized saltwater clams, marine bivalve molluscs. Within the fossil record the occurrence of this order is widespread, ranging from the Devonian Period to Recent.

Time the record covers

At least 465 million years on record.

The record covers at least 471.3 Mya to 5.333 Mya. No occurrence read is dated outside 477.1 Mya to 3.6 Mya.

6,419 occurrences of Trigoniida on record, most of them in the Late Cretaceous. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

6,419 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.

1,898 taxa

The Paleobiology Database records at least 1,412 sites for Trigoniida, 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.

Each of the 6,419 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. 874 further references are not listed.
