Barinophyton
is a genus of extinct
EARLY VASCULAR PLANTS
. It was one of the
FIRST FOSSIL PLANTS
to be found which was of Devonian age (about 420 to 360 million years ago). Plants lacked leaves or true roots; spore-forming organs or sporangia were borne on the ends of branched clusters. It’s also not clear whether barinophytes were aquatic, semi-aquatic or terrestrial. Whatever the growth habit, they’re unlikely to have occurred far from the water’s edge.
