Dictyophyllum

Dictyophyllum is an extinct genus of ferns belonging to the family Dipteridaceae. It is known from the Triassic and Jurassic periods. Like most other members of the family, it consists of multiple segments of pinnate leaflets connected to an arm, of which there were two per plant. The monophyly of the genus has been questioned, with a 2018 study suggested that the genus was polyphyletic as currently used.

297 occurrences of Dictyophyllum on record, most of them in the Late Triassic. 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

297 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.
