Type Presentation Event PalAss Annual Meeting Authors Spencer ART, Hilton J, Suttton MD Date 2011 Abstract Plants fossilised within siderite nodules (FeCO3) are often three-dimensionally preserved – such as those from the Mazon Creek Carboniferous terrestrial lagerstätte. Fossils preserved in this way have historically been studied using single-surface observation or destructive  investigative methods such as […]
