Thrinkophyton was a genus of Early Devonian land plant with branching axes.[2] Known fossils are of Lochkovian to Pragian age (419 to 408 million years ago).[3]

A cladogram published in 2004 by Crane et al. places Thrinkophyton in the core of a paraphyletic stem group of broadly defined "zosterophylls", basal to the lycopsids (living and extinct clubmosses and relatives).[4]

lycophytes

†Hicklingia

†basal groups (Adoketophyton, Discalis, Distichophytum (=Rebuchia), Gumuia, Huia, Zosterophyllum myretonianum, Z. llanoveranum, Z. fertile)

†'core' zosterophylls (Zosterophyllum divaricatum, Tarella, Oricilla, Gosslingia, Hsua, Thrinkophyton, Protobarinophyton, Barinophyton obscurum, B. citrulliforme, Sawdonia, Deheubarthia, Konioria, Anisophyton, Serrulacaulis, Crenaticaulis)

	†basal groups (Nothia, Zosterophyllum deciduum)

	lycopsids (extant and extinct members)

Hao and Xue in 2013 listed the genus as a zosterophyll.[1]
