1,553 occurrences of Rhizosolenia 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

1,553 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.

297 taxa

The Paleobiology Database records 1,149 sites for Rhizosolenia, 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.

Entered from

53 references

Each of the 1,553 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. 41 further references are not listed. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.

No 3D scan of Rhizosolenia 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.
