The Early Ludfordian leintwardinensis graptolite Event and the Gorstian-Ludfordian boundary in Bohemia (Silurian, Czech Republic)

The late Gorstian through early Ludfordian hemipelagic succession of the Prague Synform preserves a rich fossil record dominated by planktic graptoloids associated with pelagic myodocopid ostracods, pelagic and nektobenthic orthocer...

Silurian Tetinka Barrande, 1881 (Bivalvia, Spanilidae) from Bohemia (Prague Basin) and Germany (Elbersreuth, Frankenwald)

Silurian Tetinka Barrande, 1881 (Nepiomorphia Kříž, 2007) six species are characteristic for the recurring Gorstian, Ludfordian and earliest Přídolí cephalopod limestone biofacies in the Prague Basin, Bohemia and for the Saxothuring...

Ludlow Series in the Prague Synform - a progress in biostratigraphic correlation

The Ludlow Series in the Prague Synform is marked by general transition from shale-dominated Gorstian to largely carbonate sedimentation in the Ludfordian. The facies distribution and changes reflect regressive-transgressive eustati...

Silurian Kenzieana Liljedahl, 1989 (Bivalvia, Spanilidae) from Bohemia, Gotland and Sardinia

The genus Kenzieana Liljedahl, 1989 (Nepiomorphia Kříž, 2007) from Perunica, the European peri-Gondwana and Baltica is the oldest known, very long ranging Silurian (late Wenlock to late Přídolí) genus of Spanilidae Kříž, 2007, and was most probably t...

Integrated stratigraphy of the Ludfordian in the Prague Synform

The stratigraphic correlation of the Ludfordian in the Prague Synform is summarized using refined biostratigraphic data from updated conodont and graptolite faunal records. The seven graptolite and seven conodont biozones and faunal interval...

New cephalopod limestone horizon in the Ludlow (Gorstian, lower L. scanicus Biozone) of the Prague Basin (Bohemia, Perunica)

From the Prague Basin (Čechy, Perunica) was described new cephalopod limestone horizon from the Ludlow, Gorstian, lower L. scanicus Biozone. It contains the Bivalvia dominated Cardiola donigala - Slava sathon Community and cephalopod Pseudoc...

At what stratigraphical level is the mid Ludfordian (Ludlow, Silurian) positive carbon isotope excursion in the type Ludlow area, Shropshire, England?

The balance of evidence suggests that the mid Ludfordian positive carbon isotope excursion (CIE) commences in the Ludlow area, England in the uppermost Upper. Conodont and thelodont evidence, however, are consistent with the mid Ludfordi...
