Geinitzinidae

Geinitzinidae is an extinct family of Foraminifera from the late Paleozoic included in the Fusulinida that comprises genera characterized by unserial tests (chambers arranged in a single row, or line, in which walls are double layered. The outer layer is of light colored hyaline radial calcite. The inner layer is a dark, secreted, microgranular calcite.

Time the record covers

At least 130 million years on record.

The record covers at least 372.15 Mya to 241.464 Mya. No occurrence read is dated outside 382.31 Mya to 237 Mya.

571 occurrences of Geinitzinidae on record, most of them in the Permian. 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

571 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 369 sites for Geinitzinidae, 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.

71 references

Each of the 571 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. 59 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.
