Eunotia

Searched as Eunotia robusta papilio. The Paleobiology Database treats Eunotia as the accepted name.

Eunotia is a genus of diatoms. They are fresh water diatoms, specifically common in lakes, and they are also common in fossil records, although their siliceous wall design may have been lost and they appear plane, an example is Eunotia tetradon.

Time the record covers

At most 18 million years on record.

The one occurrence read is dated to somewhere between 23.04 Mya and 5.333 Mya, which is a dating window rather than a span.

1 occurrence of Eunotia on record, most of them in the Miocene. 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

1 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.

200 taxa

The Paleobiology Database records 33 sites for Eunotia, 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.

Entered from

1 reference

Each of the 1 occurrence 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 doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
