Valvulinidae

The Valvulinidae is a family of Paleocene to recent benthic textulariid Foraminifera characterized by trochospiral tests in the early stage which may become uniserial in the later. Walls are of cemented agglutinated material and have cavities created by micro-tubules, i.e. are canaliculate. Apertures have a valvular tooth or flap, at least in early stage, but may become multiple and areal in the later stage.

618 occurrences of Valvulinidae on record, most of them in the Pleistocene. 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

618 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 577 sites for Valvulinidae, 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.

74 references

Each of the 618 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. 62 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.
