Available Generic Names for Trilobites
AVAILABLE GENERIC NAMES FOR TRILOBITES P.A. JELL AND J.M. ADRAIN Jell, P.A. & Adrain, J.M. 30 8 2002: Available generic names for trilobites. Memoirs of the Queensland Museum 48(2): 331-553. Brisbane. ISSN0079-8835. Aconsolidated list of available generic names introduced since the beginning of the binomial nomenclature system for trilobites is presented for the first time. Each entry is accompanied by the author and date of availability, by the name of the type species, by a lithostratigraphic or biostratigraphic and geographic reference for the type species, by a family assignment and by an age indication of the type species at the Period level (e.g. MCAM, LDEV). A second listing of these names is taxonomically arranged in families with the families listed alphabetically, higher level classification being outside the scope of this work. We also provide a list of names that have apparently been applied to trilobites but which remain nomina nuda within the ICZN definition. Peter A.

Lower and Middle Paleozoic Stratigraphic Successions
CHAPTER 2 LOWER AND MIDDLE PALEOZOIC STRATIGRAPHIC SUCCESSIONS Middle Arenigian quartzite beds (upper Armorican Quartzite) in the Estena river section, Cabañeros National Park Gutiérrez-Marco, J.C. Rábano, I. Liñán, E. Gozalo, R. Fernández Martínez, E. Arbizu, M. Méndez-Bedia, I. Pieren Pidal, A. Sarmiento, G.N. It has already been explained how the formation of the Iberian Massif, where the Iberian Peninsula base- ment crops out, is closely linked to the development of the Late Paleozoic Variscan orogeny. The result was the intense shortening and deformation of the marine sediments previously deposited along the vast Gondwana continental margins during the Early and Middle Paleozoic. The Iberian Massif contains the most extense and fossiliferous exposures in the European Variscan orogenic chain. Its different struc- tural and paleogeographic zones include important stratigraphic successions from the Cambrian to the Devonian periods (García-Cortés et al., 2000, 2001; Gutiérrez-Marco, 2006), making up one of the key geological frameworks to understand the latest Precambrian and Paleozoic evolution of the Iberian Peninsula and Western Europe, and with an abundant record of geological and biological global events.

It is now generally known that the youngest stages of trilobites found as fossils are minute ovate or discoid bodies, not more than one millimetre in length, in which the head por tion greatly predominates. Altogether they present very little likeness to the adult form, to which, however, they are trace able through a longer or shorter series of modifications. Since Barrande2 first demonstrated the metamorphoses of trilobites, in 1849, similar observations have been made upon a number of different genera by Ford,22 Walcott,34':*>':t6 Mat thew,28- 27' 28 Salter,32 Callaway,11' and the writer.4.5-7 The general facts in the ontogeny have thus become well estab lished and the main features of the larval form are fairly well understood. Before the recognition of the progressive transformation undergone by trilobites in their development, it was the cus tom to apply a name to each variation in the number of tho racic segments and in other features of the test. -
Ptychopariid Trilobites in the Middle Cambrian of Central Bohemia (Taxonomy, Biostratigraphy, Synecology)
Ptychopariid trilobites in the Middle Cambrian of Central Bohemia (taxonomy, biostratigraphy, synecology) VRATISLAV KORDULE A revision of ptychopariid trilobites from the Middle Cambrian of central Bohemia is presented. With a few exceptions, they were previously referred only to Ptychoparia striata. Three genera are recently distinguished: Ptychoparia Hawle & Corda, 1847, Ptychoparioides Růžička, 1940, and Mikaparia gen. nov. Seven species are described: three are revised, four are new, and two is left in open nomenclature; their stratigraphical ranges and significance are discussed. A new stratigraphical subdivision of the Middle Cambrian of the Skryje-Týřovice area is suggested, including three assemblage zones and three barren zones. Four substrate and bathymetrically controlled trilobite associations are recognized in the Skryje-Týřovice area. • Key words: Bohemia, Middle Cambrian, trilobites, new taxa, biostratigraphy.

As in the previous paper, only published species are considered because illustrations are not possible. Most of the text is arranged in alphabetical order according to genera, exceptions being made in a few cases where several members of a family are kept together. ALBERTELLA Walcott, 1908 Four species were described by Walcott as belonging to Alhertella, viz, the genotype A. helena, and A. bosworthi, A. levis, and A. pa- cifica. The last named, which comes from Asia, is in reality an inde- terminate fragment and must await the finding of further material before its proper generic assignment can be made. Several new spe- cies of Albertella are in hand beside those recognized below in the disr cussion of the three previously described American species. -
