Pinacodendron
fossils are  fund extremely rare.
Pinacodendron
is an extinct genus of primitive, vascular, arborescent (tree-like) plant related to the Lycopsids (club mosses). It was part of the coal forest flora.
Pinacodendron
was rather small arborescent lycopod plants. They reached heights of over 2 - 3 metres.
Pinacodendron was primitive and unusual clubmoss. Although, unlike its better known cousins like Sigillaria, Lepidodendron, Bothrodendron
was not an arborescent clubmoss, and it did not produce any cones ! Like some herbaceous clubmoss
Pinacodendron
produced spores on it’s branches.
Pinacodendron
twigs are very, very rare and could be found only
in very few collections.
