Gleicheniaceae

The forked ferns are the family Gleicheniaceae, which includes eight genera and about 160 known species. The formerly independent families Dicranopteridaceae and Stromatopteridaceae are generally included in the Gleicheniaceae, whereas the Dipteridaceae and Matoniaceae, although closely related, are considered separate families by most authors.

Time the record covers

At least 323 million years on record.

The record covers at least 323.4 Mya to 11.7 ka. No occurrence read is dated outside 358.86 Mya to 0 Mya.

1,076 occurrences of Gleicheniaceae on record, most of them in the Late Cretaceous. 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

1,076 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.

1,701 taxa

The Paleobiology Database records 623 sites for Gleicheniaceae, 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

220 references

Each of the 1,076 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. 208 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.
