- Abstract
This section offers updates on several studies of interest in biosciences. Two paleobiologists, the Smithsonian's William DiMichele and University of Bristol's Howard Falcon-Lang, collaborated with Illinois State Geological Survey scientists John Nelson and Scott Elrick and Peabody Coal Company's Philip Ames to map the spatial structure of tall forests of lycopsids that was hidden underground in eastern Illinois. A quarry near Gilboa, New York, has exposed sandstone casts of large stumps dating from the Middle Devonian. Their lack of crowns has made it difficult to ascertain what type of plants they were. Since first discovered in 1870, they have been interpreted as progymnosperms, pteridosperms, lycopsids and cladoxylopsids.
