Serrulacaulis was a genus of early land plant with branching axes.[2] Known fossils are of Late Devonian age (383 to 359 million years ago).[1]
A cladogram published in 2004 by Crane et al. places Serrulacaulis in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).[3]
