Lenticulina (Planularia)

Planularia umbonata Loetterle, 1937, a relative of Lenticulina (Planularia) — not Lenticulina (Planularia) itself

Not Lenticulina (Planularia). This is Planularia umbonata Loetterle, 1937, a relative — both are Vaginulinidae.

18 occurrences of Lenticulina (Planularia) on record, most of them in the Miocene. 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

18 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.

392 taxa

The Paleobiology Database records 15 sites for Lenticulina (Planularia), and this reads all 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.

3 references

Each of the 18 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. Each entry links to the Paleobiology Database's own record for the work.

No 3D scan of Lenticulina (Planularia) was found in Sketchfab.

Smithsonian Open Access and MorphoSource were not reached for this taxon, so this list is what the others held rather than everything there is.

This is what the site found, which is not the same as what exists.
