  • A New Middle Cambrian Trilobite with a Specialized Cephalon from Shandong Province, North China
    Editors' choice A new middle Cambrian trilobite with a specialized cephalon from Shandong Province, North China ZHIXIN SUN, HAN ZENG, and FANGCHEN ZHAO Sun, Z., Zeng, H., and Zhao, F. 2020. A new middle Cambrian trilobite with a specialized cephalon from Shandong Province, North China. Acta Palaeontologica Polonica 65 (4): 709–718. Trilobites achieved their maximum generic diversity in the Cambrian, but the peak of morphological disparity of their cranidia occurred in the Middle to Late Ordovician. Early to middle Cambrian trilobites with a specialized cephalon are rare, especially among the ptychoparioids, a group of libristomates featuring the so-called “generalized” bauplan. Here we describe an unusual ptychopariid trilobite Phantaspis auritus gen. et sp. nov. from the middle Cambrian (Miaolingian, Wuliuan) Mantou Formation in the Shandong Province, North China. This new taxon is characterized by a cephalon with an extended anterior area of double-lobate shape resembling a pair of rabbit ears in later ontogenetic stages; a unique type of cephalic specialization that has not been reported from other trilobites. Such a peculiar cephalon as in Phantaspis provides new insights into the variations of cephalic morphology in middle Cambrian trilobites, and may represent a heuristic example of ecological specialization to predation or an improved discoidal enrollment. Key words: Trilobita, Ptychopariida, ontogeny, specialization, Miaolingian, Paleozoic, Longgang, Asia.

' FIFTH CONTRIBUTION TO NOMENCLATURE OF CAMBRIAN FOSSILS By CHARLES E. RESSER Curator, Division of Stratigraphic Paleonlolo<jy, U. S. National Museum This is the fifth in the series of papers designed to care for changes necessary in the names of Cambrian fossils. When the fourth paper was published it was hoped that further changes would be so few and so obvious that they could be incorporated in the Cambrian bibliographic summary, and would not be required to appear first in a separate paper. But even now it is impossible to gather all of the known errors for rectification in this paper. For example, correc- tion of some errors must await the opportunity to examine the speci- mens because the published illustrations, obviously showing incorrect generic determinations, are too poor to permit a proper understanding of the fossil. In the other instances where new generic designations are clearly indicated, erection of new genera should await the pub- lication of a paper with illustrations, because better-preserved speci- mens are in hand, or undescribed species portray the generic charac- teristics more fully and should therefore be chosen as the genotypes.

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.

    Intraspecific variation and taphonomic alteration in the Cambrian (Furongian) agnostoid Lotagnostus americanus: new information from China SHANCHI PENG, LOREN E. BABCOCK, XUEJIAN ZHU, PER AHLBERG, FREDRIK TERFELT & TAO DAI The concept of the agnostoid arthropod species Lotagnostus americanus (Billings, 1860), which has been reported from numerous localities in the upper Furongian Series (Cambrian) of Laurentia, Gondwana, Baltica, Avalonia, and Siberia, is reviewed with emphasis on morphologic and taphonomic information afforded by large collections from Hunan in South China, Xinjiang in Northwest China, and Zhejiang in Southeast China. Comparisons are made with type and topotype material from Quebec, Canada, as well as material from elsewhere in Canada, the USA, the United Kingdom, Sweden, Russia, and Kazakhstan. The new information clarifies the limits of morphologic variability in L. americanus owing to ontogenetic changes and variation within holaspides, including inferred microevolution. It also provides details on apparent variation of taphonomic origin. The Chinese collections demonstrate a moderately wide variation in L. americanus, indicating that arguments favoring restriction of Lotagnostus species to narrowly defined, geographi- cally restricted forms are unwarranted. Species described as L. trisectus (Salter, 1864), L. asiaticus Troedsson, 1937, and L. punctatus Lu, 1964, for example, fall within the range of variation observed in L. americanus, and are regarded as ju- nior synonyms. The effaced form Lotagnostus obscurus Palmer, 1955 is removed from synonymy with L. americanus.A review of the stratigraphic distribution of L. americanus as construed here shows that the earliest occurrences of the spe- cies in all regions of the world are nearly synchronous. • Key words: Cambrian, Furongian, agnostoid, Lotagnostus americanus, China, Quebec.

In several respects trilobite development and form appears comparable with that which may have charac- terized the ancestor of most or all euarthropods, giving studies of trilobite body organization special relevance in the light of recent advances in the understanding of arthropod evolution and devel- opment.

In contrast, the Ordovician diversification of trilobites, although contributing greatly to the overall diversity within the clade, did so within a nar- rower range of trunk conditions.
