Sigillaria
''Sigillaria'' is a genus of extinct, spore-bearing, arborescent (tree-like) plants. It was a lycopodiophyte, and is related to the lycopsids, or club-mosses,〔 but even more closely to quillworts, as was its associate ''Lepidodendron''. ==Fossil records== This genus is known in the fossil records from the Late Carboniferous period 〔(Hans' Paleobotany Pages - The clubmoss tree Sigillaria )〕 but dwindled to extinction in the early Permian period (age range: from 383.7 to 254.0 million years ago).〔(Encyclopaedia Britannica )〕 Fossils are found in United States, Canada, China, Korea, Tanzania and Zimbabwe.〔(Paleobiology Database )〕
