Short summary
We discovered two new species of Sigillariostrobus cones belonging to the extinct arborescent lycophytes (club mosses). These cones usually fall apart, so finding new intact cones is rare and very important for understanding the diversity of Carboniferous lycophytes. The two species are the first from Britain, although the other cones are known from Europe. One of the cone species has Laevigatisporites glabratus-type spores inside; the other has Tuberculatisporites brevispiculus-type spores.
