Anisophyton

Anisophyton; Temporal range: Emsian PreꞒ Ꞓ O S D C P T J K Pg N
Scientific classification

Genus:	†Anisophyton

Anisophyton was a genus of Early Devonian land plant with branching axes.^[2] Known fossils are of Emsian age (408 to 393 million years ago).^[1]

A cladogram published in 2004 by Crane et al. places Anisophyton in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).^[3]
