Pecopteris was a form genus of leaves from several unrelated plant groups[1] that flourished the early Carboniferous period and on to c. 250 Ma. Pecopteris first appeared in the Devonian period, but flourished in the Carboniferous, especially the Pennsylvanian. Plants bearing these leaves went extinct around the beginning of the Permian period.

[edit] Etymology

Pecopteris is derived from the Greek pekin, (to comb), and pteris, (a fern)[2]. This is because the leaflets of Pecopteris fronds are arranged like the teeth on a comb.[3]

[edit] Species

As of 1997, there have been 250-300 species assigned to Pecopteris[4].
