By H. O. FLETCHER. Curator of Palaeontology, The Australian Museum. (Plates xv-xvi.) In this paper three new species of trilobites are described from a Lower Silurian horizon at Borenore, near Orange, New South Wales, as Encrinurus borenorensis, Phacops macdonaldi and Dicranogmus bartonensis. The genus Encrinurus Emmrich, 1844, is discussed and it is considered that the genus Gryptonymus Eichwald, 1825, is an abandoned name and cannot be used outside certain limits. Reference is made to the recorded Australian species of the family Lichidae and their geological age. The fossil material was originally found and forwarded to the Australian Museum by Mr. George McDonald, of "Rosyth", Borenore, on whose property the new horizon of fossils is situated. The author visited the locality later and collected additional specimens of all the described species. My thanks are due to Mr. McDonald for his assistance and interest, which have made possible the preparation of this paper. I am also indebted to Mr. F. Booker and Mr. L. Hall, of the Geological Survey of New South Wales, for assistance in determining the geological succession of the area.

A total of 15 families; 36 genera and 53 species are documented herein, including a new genus and seventeen new species; fourteen of which remain under open nomenclature. Most of the trilobites in the British late Silurian are restricted to the shelf, and predominantly occur in the Elton, Bringewood, Leintwardine, and Whitcliffe groups of Wales and the Welsh Borderland. The Elton to Whitcliffe groups represent a shallowing upwards sequence overall; each is characterised by a distinct lithofacies and fauna. The trilobites and brachiopods of the Coldwell Formation of the Lake District Basin are documented, and are comparable with faunas in the Swedish Colonus Shale and the Mottled Mudstones of North Wales. Ludlow trilobite associations, containing commonly co-occurring trilobite taxa, are defined for each palaeoenvironment.

  • 26. a New Find of Encrinurus from Japan. by Toshio
    106 [Vol. 17, 26. A New Find of Encrinurus from Japan. By Toshio SUGIYAMA. (Comm. by H. YABE,M.LA., April 12, 1941.) In a recent paper", the writer reported on the occurrence of a trilobite under the name of Encrinurus kitakamiensis without any description or figure from Kusayami-zawa at the southern foot of Takainari-yama, Hikoroiti-mura, Kensen-gun, Iwate-ken. The several pygidia obtained from the black limestone in the upper part of the 2nd horizon of the Kawauti series2' are often found in association with a brachiopod probably referable to Plectambonites. At first, this fossil was referred to Encrinurus (sens. ext. ), a genus flourished in the Ordovician and Gotlandian. However, later study reveals that the pre- sent pygidia bear many characters reminding one strongly of Corono- cephalus, a subgenus of Encrinurus established by A. W. Grabau3' in 1923 on Encrinurus (Coronocephalus) rex Grabau from the Sintan Shale of Hupeh province in the Central China. The comprehensive study of Coronocephalus by Y. Wang4' has re- cently made clear the subgeneric status. According to him it is a trilobite monotypic at present, and its genotype has an extensive geogra- phical distribution in China, being known from Kueichow, Szechuan, Hupeh, Kiangs, Anui, and Kiangsu provinces ; geologically it is re- stricted to the Sintan Shale of China. The subgeneric diagnosis given by Wang is as follows : "Cephalic shield sublunate to subtriangular in outline, with the genal angles produced backward into long spines beyond the posterior end of the carapace. Glabella clavate, carrying three deep and broad transverse furrows and three nodular lobes in its narrower part.

  • Quantifying Intra-And Interspecific Variability in Trilobite Moulting
    Palaeontologia Electronica palaeo-electronica.org Quantifying intra- and interspecific variability in trilobite moulting behaviour across the Palaeozoic Harriet B. Drage ABSTRACT Moulting of a protective exoskeleton is a defining characteristic of Euarthropoda, and its evolution can be explored through analysing moults preserved in the fossil record. Our most complete record comes from the Trilobita, which were uniquely flexi- ble in moulting compared to other arthropod groups. This study presents the first broad-scale quantitative analysis of trilobite moulting. Trends in moulting variability with taxonomy and through the Palaeozoic are explored by looking at the occurrences of six moulting characteristics: opening of the facial and ventral sutures; and disarticulation of the cephalon, cranidium, thorax, and pygidium. Significant differences in moulting across taxonomic and temporal groups were identified using chi-squared analyses, and biases with sampling and diversity identified through correlation analyses. Occur- rences of facial and ventral suture opening, and cephalic disarticulation, significantly varied between orders and Epochs. These likely result from the prevalence of ventral suture moulting in Redlichiida and cephalic disarticulation in Phacopida, and their rele- vant diversity patterns. The data show high levels of intraspecific variability in moulting; ~40% of species showed multiple moulting characteristics. Redlichiida and the early Cambrian are the most intraspecifically variable, with greater variability likely an adap- tation to the initial radiation and establishment of trilobites into new niches. The lon- gest-lived group, Proetida, showed the lowest levels of intraspecific variability, which may suggest greater specialism later in the Palaeozoic. Ultimately, datasets such as this advocate the need to study behaviours in the fossil record on a broad-scale, because they help us build a comprehensive picture of extinct groups as living animals.

The samples were provided to the author by Mr. Al Shefsky ofPele Mountain Resources to be processed in Toronto for diamonds and indicator minerals. The results were initially provided to Pele Mountain Resources verbally. This report represents a summary of analysis, photo documentation, reference material and descriptions relevant to the sample. A secondary purpose of this analysis is an academic study of the surface microtextures of minerals such as quartz and zircon (see Mahaney 2002; Mahaney and Milner 1997). Both spheroidal garnets, mainly spessartite, and quartz, which in Wawa lamprophyre, Ogoki River samples and these Attawapiskat River samples are close to pristine and are lacking in significant fracturing that might be incurred in either glacial or river transport. Kyanite is another mineral, present in this sample, with potential for further research (Fipkie et ai., 1999). Morphological changes for distance of transport from the pipe has been given for pyrope. Dummet (1984) described the spherical form, "orange peel" surface texture of the pyrope at the pipe and the subsequent breaking and rounding of the mineral with distance of transport.

Grabau (1924) erected the trilobite genus Coronocephalus with the type species Encrinurus (Coronocephalus) rex Grabau, 1924 from Kaochiapien Sh, Jiangsu, China. It is still used as a valid genus name in Trilobita (e.g. Jell & Adrain, 2002). Subsequently, the genus group name Coronocephalus was proposed by Orlova-Bienkowskaja (1995) for a subgenus of the cladoceran genus Simocephalus Schoedler, 1858. It is still used as a valid generic name in Cladocera (e.g. Orlova-Bienkowskaja, 1998, 2001). The subgenus has three species. Thus, the genus group name Coronocephalus Orlova-Bienkowskaja, 1995 is a junior homonym of Coronocephalus Grabau, 1924. So we peopose Crownocephalus nom. nov. as a replacement name for Coronocephalus Orlova- Bienkowskaja, 1995. Etymology: The name is derived from the English word “crown”.

Early Llanvim brachiopods and trilobites occur together with molluscs as clasts in a serpentine conglomerate thought to have been formed in an oceanic island setting during an early closing of the lapetus Ocean. The brachiopods show strong North American affinities while the trilobites are a mixture of North American and Balto-Scandian types. The fauna suggests that in oceanic island settings, fauna! provincial affinity in support of tectonic models should be used with caution. The twelve brachiopod genera include: Rutrumella implexa gen. et sp. nov., Ottadalenites incertus gen. et sp. nov., Neumania gen. nov. (type species: Atelelasma atlanticus Neuman, 1976) and Trondorthis subcircularis sp. nov.

  • Experimental Biomechanics on Trinucleid Fringe Pits
    Oberlin College, Depts. of Geology and Biology Spring 2017 Experimental biomechanics of trinucleid! fringe pits (Trilobita) Kirk Pearson Depts. of Geology and Biology, Oberlin College Oberlin, OH 44074 [email protected]! !Abstract The morphometric uniqueness of the trinucleid family of fossil arthropods, known as the trilobites, has led to a considerable amount of attention in paleontology literature. In particular, the distinctive hourglass-shaped pits that dot their anterior have been the subject of debate for over a century. Though anatomically well understood, their function remains unknown. Many proposals have been suggested, including its use as a sieve for filter-feeding, a strong shield for defense, and a sensory mechanism to compensate for their blindness. Despite the wide range of speculations, no study has attempted to model these hypotheses experimentally. Flume experiments and mechanical strength tests using a tenfold scale, 3D-printed model of a trinucleid head suggest that the dominant theories for over a century, filter-feeding and skeletal strengthening, are not well supported. It is proposed that the results suggest that the pits are an ontogenetic signature that optimize the cephalon’s growth to be maximal, providing trinucleids !with an excellent mechanism for plowing through fine-grained silts and clays. !Introduction and Background !Anatomical Background The asaphid trilobite family Trinucleidae were benthic dwellers in the Ordovician oceans (Campbell 1975). They are best characterized by their wide, perforated head shield located on the cephalon (Fig I). These perforations have traditionally been referred to as “fringe pits,” or “pits,” while the fringe has lent itself to a popular nickname for the family: “lace 5 mm collar trilobites.” Previous work has suggested that the fringe pits were Fig I: C.
