Eohostimella heathana is an early, probably terrestrial, "plant" known from compression fossils [2] of Early Silurian age (Llandovery, around 440 to 430 million years ago [3]). The chemistry of its fossils is similar to that of fossilised vascular plants, rather than algae. [2] Its anatomy constitutes upright, cylindrical tubes, [2] with a thickened outer cortex, [4] which might have contained traces of lignin or a similar compound, [2] even though no tracheids or similar vessels have been found; [4] the lignin-like compound was presumably associated with its thick outer cortex. [5] It branched dichotomously and might have borne small spines. [6] It was probably affiliated with the rhyniophytes. [4]
