Pecopteris is a very common

filicalean ferns, and at least one seed fern.[1]
[2] Pecopteris first appeared in the Devonian period, but flourished in the Carboniferous, especially the Pennsylvanian. Plants bearing these leaves became extinct in the Permian period, due to swamps disappearing and temperatures on Earth dropping.[3]

Etymology

Pecopteris is derived from the Greek pekin, (to comb), and pteris, (a fern).[4] This is because the leaflets of Pecopteris fronds are arranged like the teeth on a comb.[5]

Species

As of 1997, there have been 250-300 species assigned to Pecopteris.[6]

In

form genus Pecopteris was located in outcrop Morro Papalé in the city of Mariana Pimentel. They are in the geopark Paleorrota in Rio Bonito Formation and date from Sakmarian in Permian.[7]
