Lingula
Lingula is a genus of brachiopods within the class Lingulata. Lingula has been historically considered a 'living fossil' with members stretching back to the Cambrian, but those fossils likely represent other genera in the order Lingulida and the genus likely first originated in the early Cenozoic or late Cretaceous. Like its relatives, it has two unadorned organo-phosphatic valves and a long fleshy stalk. Lingula lives in burrows in barren sandy coastal seafloor and feeds by filtering detritus from the water. It can be detected by a short row of three openings through which it takes in water (sides) and expels it again (middle).

Time the record covers
At least 501 million years on record.
The record covers at least 504.5 Mya to 2.58 Mya. No occurrence read is dated outside 506.5 Mya to 11.7 ka.
1,046 occurrences of Lingula on record, most of them in the Devonian. 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.

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 951 sites for Lingula, 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 1,046 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. 358 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.
