Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family contains around 5,500 described species in about 90 genera, the largest with over 2,000 species being the "true sedges" or Carex.

Time the record covers
At least 119 million years on record.
The record covers at least 119.57 Mya to 11.7 ka. No occurrence read is dated outside 125.77 Mya to 0 Mya.
916 occurrences of Cyperaceae 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
916 occurrences- Early Cretaceousunder 1%
- Late Cretaceousunder 1%
- Paleoceneunder 1%
- Eocene5%
- Oligocene6%
- Miocene47%
- Pliocene12%
- Pleistocene26%
- Holocene3%
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 named rock units Cyperaceae has been recovered from, largest first. Drawn where the rock is now, not where it formed. 27 further formations hold fewer occurrences each and are not listed. 812 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 241 sites for Cyperaceae, and this reads 240 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.

Each of the 916 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. 84 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.
