Strophomena is a genus of brachiopods belonging to the family Strophomenidae in the order Strophomenida, named by Rafinesque in 1824. They were stationary epifaunal suspension feeders.

At least 217 million years on record.

The record covers at least 477.1 Mya to 259.857 Mya. No occurrence read is dated outside 486.85 Mya to 254.14 Mya.

998 occurrences of Strophomena on record, most of them in the Ordovician. 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

998 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 872 sites for Strophomena, 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 998 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. 151 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.
