Stenochlaena

Stenochlaena is a genus of ferns of the plant family Blechnaceae. Six species were formally accepted in an April 2013 scientific review of the genus, first written some years earlier and submitted in 2009. One additional species S. hainanensis awaits confirmation of its difference from S. palustris by means of differences in fertile material and/or its formal publication. One additional likely species grows naturally in Cameroon, Africa, recognised with the descriptive name Stenochlaena sp. 'Cameroon' but it awaits formal description.

11 occurrences of Stenochlaena on record. 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

11 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.

The named rock units Stenochlaena has been recovered from, largest first. Drawn where the rock is now, not where it formed. 7 occurrences have no formation on record, which is common for older literature.

The Paleobiology Database records 11 sites for Stenochlaena, 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

4 references

Each of the 11 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. 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.
