But for the past few months, Albanese has been studying paleobotany for a diorama called "The Hottest Day on Earth." The garden includes vanished genera such as Tempskya (a trunkless tree fern of the Cretaceous period) and
Sigillaria (a spore-bearing tree of the Late Carboniferous period).
Likewise, "Several specialized mechanisms for accommodating girth increase evolved: tangential interarea expansion in
Sigillaria and Synchysidendron, interarea fissuring in Diaphorodendron, and subcushion cellular expansion in Lepidodendron" (Bateman et al., 1992, p.
Clement seemed to prefer collecting tree trunk and woody material of Lepidodendron,
Sigillaria, Stigmaria, and Calamites, over leafy material as only three specimens of leaves (Pecopteris and Neuropteris) occur in the collection.
