A Complete Reconstruction of the Hyolithid Skeleton
U-Pb (zircon) age constraints on the timing and duration of Wenlock (Silurian) paleocommunity collapse and recovery during the “Big Crisis”
Testing the limits of Paleozoic chronostratigraphic correlation via high-resolution (<500 k.y.) integrated conodont, graptolite, and carbon isotope (δ 13 C carb ) biochemostratigraphy across the Llandovery–Wenlock (Silurian) boundary: Is a unified Phanerozoic time scale achievable?
Vertebrate extinctions and reorganizations during the Late Silurian Lau Event
Carbonate platform evolution and conodont stratigraphy during the middle Silurian Mulde Event, Gotland, Sweden

Sudden appearances of Silurian conodont lineages: Provincialism or special biofacies?
Many conodont lineages that appear in the Ludlovian on Gotland and elsewhere have no known earlier record anywhere. The closest relatives are found not in the earliest Ludlovian but in the latest Llandoverian-earliest Wenlockian or in still older beds. Ordinary biofacies and lithofacies models fail to explain the observed distribution, since such lineages appear in all of the different facies identified. Either these lineages evolved in an as yet unsampled province, the isolation of which broke down gradually during the Ludlovian, or their appearance reflects changes in the chemistry of the seawater. If the latter interpretation applies, then it indicates that conodonts can be used as sensitive indicators of fluctuations in the marine realm.
