Morphology and Developmental Traits of the Trilobite Changaspis Elongata from the Cambrian Series 2 of Guizhou, South China
Morphology and developmental traits of the trilobite Changaspis elongata from the Cambrian Series 2 of Guizhou, South China GUANG-YING DU, JIN PENG, DE-ZHI WANG, QIU-JUN WANG, YI-FAN WANG, and HUI ZHANG Du, G.-Y., Peng, J., Wang, D.-Z., Wang, Q.-J., Wang, Y.-F., and Zhang, H. 2019. Morphology and developmental traits of the trilobite Changaspis elongata from the Cambrian Series 2 of Guizhou, South China. Acta Palaeontologica Polonica 64 (4): 797–813. The morphology and ontogeny of the trilobite Changaspis elongata based on 216 specimens collected from the Lazizhai section of the Balang Formation (Stage 4, Series 2 of the Cambrian) in Guizhou Province, South China are described. The relatively continuous ontogenetic series reveals morphological changes, and shows that the species has seventeen thoracic segments in the holaspid period, instead of the sixteen as previously suggested. The development of the pygid- ial segments shows that their number gradually decreases during ontogeny. A new dataset of well-preserved specimens offers a unique opportunity to investigate developmental traits after segment addition is completed. The ontogenetic size progressions for the lengths of cephalon and trunk show overall compliance with Dyar’s rule. As a result of different average growth rates for the lengths of cephalon, trunk and pygidium, the length of the thorax relative to the body shows a gradually increasing trend; however, the cephalon and pygidium follow the opposite trend. Morphometric analysis across fourteen post-embryonic stages reveals growth gradients with increasing values for each thoracic segment from anterior to posterior. The reconstruction of the development traits shows visualization of the changes in relative growth and segmentation for the different body parts. -

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.

2nd International Trilobite Conference (Brock University, St. Catharines, Ontario, August 22-24, 1997) ABSTRACTS. Characters and Parsimony. Jonathan M. Adrain, Department of Palaeontology, The Natural History Museum, London SW7 5BD, United King- dom; Gregory D. Edgecombe, Centre for Evolutionary Research, Australian Museum, 6 College Street, Sydney South, New South Wales 2000, Australia Character analysis is the single most important element of any phylogenetic study. Characters are simply criteria for comparing homologous organismic parts between taxa. Homology of organismic parts in any phylogenetic study is an a priori assumption, founded upon topological similarity through some or all stages of ontogeny. Once homolo- gies have been suggested, characters are invented by specifying bases of comparison of organismic parts from taxon to taxon within the study group. Ideally, all variation in a single homology occurring within the study group should be accounted for. Comparisons are between attributes of homologous parts, (e.g., simple presence, size of some- thing, number of something), and these attributes are referred to as character states. Study taxa are assigned member- ship in one (or more, in the case of polymorphisms) character-state for each character in the analysis. A single char- acter now implies discrete groupings of taxa, but this in itself does not constitute a phylogeny. In order to suggest or convey phylogenetic information, the historical status of each character-state, and of the the group of taxa it sug- gests, must be evaluated. That is, in the case of any two states belonging to the same character, we need to discover whether one state is primitive (broadly speaking, ancestral) or derived (representative of an evolutionary innovation) relative to the other. -

Chinese-To-English Translation of Publicity on Chinese Minority Culture from Narrative Perspectives
Journal of Literature and Art Studies, August 2019, Vol. 9, No. 8, 897-906 doi: 10.17265/2159-5836/2019.08.012 D DAVID PUBLISHING Chinese-to-English Translation of Publicity on Chinese Minority Culture From Narrative Perspectives XIAO Tang-jin Guizhou Minzu University, Guiyang, China Narrative is a literary notion. In narrative translation theory, narrative involves personal narrative, public narrative, disciplinary narrative, and meta-narrative. This paper adopts the notions of personal narrative, public narrative, and meta-narrative to analyze specific cases concerning the Chinese-to-English translation on Chinese minority culture publicity, proposes two narrative translation models, namely, the annotation narrative translation model and the manipulative narrative translation model, and explores the concrete translation procedures and the embodied meta-narrative, covering introduction to minority tales, minority festivals, and minority customs. Narrative translation research is part of the multidisciplinary or interdisciplinary turn in the 21st century, and this research is an organic part of cross-cultural communication translatology. Keywords: narrative, Chinese-to-English translation, publicity on Chinese minority culture, model Foreword Cross-cultural communication translatology explores translation theories and practice from the perspectives of cross-cultural communication based on multiple disciplines. Thus, it shows interdisciplinary, intercultural and interlingual features (Xiao, 2018). This means that it is different from conventional approaches to translation in theory and practice, such as form equivalence and functional equivalence. Nowadays, narrative, an approach in literary studies, and sociology, a discipline which studies social structure, social mobility, and other social issues, are also adopted in translation studies. They are labeled as “interdisciplinary turn”, “sociological turn”, “power turn”, and other things alike. -

Shales of the Šárka Formation exposed in the excavation on Červený vrch Hill at Praha-Vokovice contain a common but monotonous assem- blage of phyllocarids associated with other extremely rare arthropods. Almost all trilobite remains (genera Ectillaenus Salter, 1867, Placoparia Hawle et Corda, 1847 and Asaphidae indet.) occur in a single horizon of siliceous nodules of stratigraphically uncertain position, while the surprising occurrence of possible naraoid trilobite (Pseudonaraoia hammanni gen. n., sp. n.) comes from dark grey shales. The general character of the arthropod assemblage char- acterized by an expressive dominance of planktonic and/or epi-planktonic elements (phyllocarids) indicates a specific life environment (most probably due to poor oxygenation). This association corresponds to the assemblage preceding the Euorthisina-Placoparia Community sensu Havlíček and Vaněk (1990) in the lower portion of the Šárka Formation.
