Contribution to the biostratigraphy around the Lochkovian-Pragian boundary in Central Asia (graptolites, tentaculites, conodonts)
Autor: A. I. Kim, O. H. Walliser, T. N. Koren
Publikováno v: Senckenbergiana lethaea. 87:187-219
Graptolites, conodonts and pelagic tentaculites were collected from three sections (Shishkat, Kyk, and Almaly) in the Southern Tien-Shan, Central Asia, in order to integrate these biostratigraphic sequences around the Lochkovian-Pragian boundary. The

An Unusually Diverse Llandovery (Silurian) Diplograptid Fauna from the Southern Urals of Russia and Its Evolutionary Significance
Autor: R. B. Rickards, T. N. Koren
Publikováno v: Palaeontology. 47:859-918
This vesiculosus Biozone assemblage of chemically-isolated graptolites from the Orenburg District of Russia was obtained from limestones associated with pillow lavas of the Sakmara Formation of Silurian–Early Devonian age. It comprises 30 species,

Publikováno v: Lethaia. 18:125-146
The Skala horizon of Podolia has been under discussion as a possible candidate for the stratotype of the fourth Silurian series (primary subdivision) in the international standard chronostratigraphical scale. After a brief survey of the history of in

Extinction of the graptolites
Autor: R. B. Rickards, T. N. Koren
Publikováno v: Geological Society, London, Special Publications. 8:457-466
Summary Graptoloids became extinct in latest Early Devonian (Pragian) times, and dendroids in the late Carboniferous. There is insufficient information for the other six graptolite orders to suggest when they might have become extinct, so that in the

Virgellar meshworks and sicular spinosity in Llandovery graptoloids
Autor: R. B. Rickards, T. N. Koren
Publikováno v: Geological Magazine. 111:193-204
SummaryOrthograptus obuti sp.nov. and Orthograptus insectiformis Nicholson are shown to exhibit a complex proximal meshwork developed from a much-divided virgella which closely resembles retiolitid clathrial and lacinial networks. The virgellar meshw
