    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.

In the middle part of the section, specimens representing members of several trilobite families can be found, largely of the Ellipsocephalidae, and Paradoxididae, accompanied by the Solenopleuridae, Dorypygidae, Palaeolenidae and trilobites from the informal Conomicmacca/Myopsolenites clade.

A.: Trilobites of the Hagastrand Member (Tøyen Formation, lowermost Arenig) from the Oslo Region, Norway. Part Il: remaining non-asaphid groups. Norsk Geologisk Tidsskrift, Vol. 79, pp. 259-280. Oslo 1999. ISSN 0029-196X. This is Part Il of a two-part description of the trilobite fauna of the Hagastrand Member (Tøyen Formation) in the Oslo, Eiker­ Sandsvær, Modum and Mjøsa areas. In this part, the non-asaphid trilobites are described, while the asaphid species have been described previously. The history and status of the Tremadoc-Arenig Boundary problem is also reviewed, and I have found no reason to insert a Hunnebergian Series between the Tremadoc and the Arenig series, as has been suggested by some workers. Descriptions of the localities yielding this special trilobite fauna are provided. Most of the 22 trilobite species found in the Hagastrand Member also occur in Sweden. The 12 non-asaphid trilobites described herein belong to the families Metagnostidae, Shumardiidae, Remopleurididae, Nileidae, Cyclopygidae, Raphiophoridae, Alsataspididae and Pliomeridae. One new species is described; Robergiella tjemviki n. sp. Ole A. Hoel, Paleontologisk Museum, Sars gate l, N-0562 Oslo, Norway.

    The depositional environment and taphonomy of the Homerian Aulacopleura shales fossil assemblage near Lodìnice, Czech Republic (Prague Basin, Perunican microcontinent) NIGEL C. HUGHES, JIØÍ KØÍ, JOSEPH H.S. MACQUAKER & WARREN D. HUFF Excavation of Joachim Barrande’s classic fossil locality of the “Aulacopleura shales” exposed on Na Černidlech Hill, near Loděnice reveals that most specimens were recovered from a 1.4 m interval exposed in “Barrande’s pits”. These are located at the eastern end of a 0.4 km trench dug in the mid 1800’s to expose the interval along strike. Over an hundred bedding planes occur within the 1.4 m interval, and thousands of articulated trilobites have been collected at the site. In- dividual bed surfaces vary in the density, size, and taxonomic composition of the fossils contained. Some preserve a di- verse benthic shelly fauna, others are almost exclusively dominated by the trilobite Aulacopleura koninckii, and a third variety is apparently barren of all shelly fossils. Isolated sclerites of A. koninckii are rare, and on almost all bedding sur- faces exoskeletons are predominantly partially articulated and lack both alignment and sclerite fragmentation. The oc- currence of A. koninckii conforms in many ways to the characteristics of a Type I trilobite lagerstätte of Brett et al. (2012). The presence of enrolled A. koninckii suggests that final burial may have resulted from relatively rapid obrution, although the condition of partial articulation indicates that many carcasses or exuviae partially disaggregated before burial. The mean size and density of A. koninckii specimens varies markedly among bedding planes, with some assem- blages entirely comprised of juveniles, suggesting that notably dense trilobite clustering was not restricted only to repro- ductively mature individuals.

  • The Viruan (Middle Ordovician) of Öland
    The Viruan (Middle Ordovician) of Öland By Valdar Jaanusson ABSTRACT.-The stratigraphy and lithology of the Viruan (Middle Ordovician) Iimestones of the bed-rock of Öland are described based on three bares and on field work in the outcrop area. A combined litho- and bio-stratigraphic classification (termed topo-stratigraphic) is introduced for the described sequence. The names of the Estonian stages (Aserian, Lasnamägian, Uhakuan, and Kukrusean) are used as chrono-stratigraphic references instead of the previous Swedish names of the units of stage category (Platyurus, Schroeteri, Crassicauda, and Ludibundus, re­ spectivcly). New topo-stratigraphic divisions are Segerstad Limestone (of Aserian age), Skärlöv, Seby, and Folkeslunda Limestones (of Lasnamägian age), Furudal, Källa, and Persnäs Lime­ stones (of Uhakuan age), and Dalby Limestone (of Kukrusean age in the bed-rock of Öland). The Aserian Lasnamägian topo-stratigraphic divisions have the same lithological characteris­ and tics throughout Öland. The Uhakuan beds are developed as calcilutites (Furudal Limestone) on southern Öland continuing as a tongue (Källa Limestone) on northern Öland. The middle and upper part of the Uhakuan beds of northern Öland consist of calcarenites (Persnäs Limestone) lithologically indistiguishable from the Kukrusean Dalby Limestone which forms the bed-rock only on northern Öland. Within the Segerstad Limestone two zones are distinguished (z. of Angelinoceras latum and z. of Illaenus planifrons).H ouvr ' s zones of Lituites discors, L. lituus, and L. perfectus are of Lasna­ mägian age, and their stratigraphic position and fauna! characteristics are described.
