Nematophyta

Nematophyta; Rentang waktu: Silur Atas – Famennium
	Kutikula Cosmochlaina yang didapatkan dari Burgsvik Beds dengan metode persiapan fosil (en). Diameter sel-selnya kira-kira berukuran 12 μm.
Klasifikasi ilmiah
Kerajaan:	Plantae
Filum:	"Nematophyta"
Famili dan genera
	Famili Nematothallaceae: Nematothallus Lang, 1937 ; Cosmochlaina Edwards, 1986; Famili Nematophytaceae: Nematoplexus Lyon, 1962 ; Nematasketum Burgess and Edwards, 1988 ; Prototaxites Dawson, 1859;

Nematophyta adalah kelompok organisme darat yang bersifat parafiletik, mungkin termasuk beberapa tumbuhan dan juga ganggang.^[1]^[2] Nematophyta hanya diketahui dari catatan fosil, dari zaman Silur hingga Devon Awal di Chert Rhynie.^[3]

Sedikitnya definisi yang jelas mengenai nematophyta menjadikannya sebagai takson keranjang sampah. Seluruh jenis tabung dan kutikula berpola sel dari Silur disebut "nematophyta".
