Guttulina

Guttulina is a genus of nodosariacean forams belonging to the Polymorphinidae and subfamily Polymorphinidae. The test is ovoid to elongate, inflated chambers added in a quinqueloculine spiral series, 144 deg. apart, each successive chamber extending further from the base but strongly overlapping. Sutures depressed, aperture radiate. As with all Nodosarioidea the wall is of finely perforate, radial laminated calcite.

No picture of Guttulina was found. Wikipedia, Wikidata, iDigBio and Smithsonian Open Access were searched and had none. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Guttulina, or no answer at all. This entry cannot say which.

273 occurrences of Guttulina on record, most of them in the Miocene. 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

273 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.

Found in the same rock

1,034 taxa

The Paleobiology Database records 224 sites for Guttulina, and this reads all of them. Of that, one read hit the database's own return limit, so every count below is a floor rather than a total. 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.

Entered from

55 references

Each of the 273 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. 43 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.
