Bryozoan Studies 2019
BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

Isocrinid Crinoids from the Late Cenozoic of Jamaica
A tlantic G eology 195 Isocrinid crinoids from the late Cenozoic of Jamaica Stephen K. Donovan Department of Geology, University of the West Indies, Mona, Kingston 7, Jamaica Date Received April 8, 1994 Date A ccepted A ugust 26, 1994 Eight species of isocrinines have been documented from the Lower Cretaceous to Pleistocene of Jamaica. New finds include a second specimen of a Miocene species from central north Jamaica, previously regarded as Diplocrinus sp. but reclassified as Teliocrinus? sp. herein. Extant Teliocrinus is limited to the Indian Ocean, although Miocene specimens have been recorded from Japan, indicating a wider distribution during the Neogene. One locality in the early Pleistocene Manchioneal Formation of eastern Jamaica has yielded three species of isocrinine, Cenocrirtus asterius (Linne), Diplocrinus maclearanus (Thomson) and Neocrinus decorus Thomson. These occur in association with the bourgueticrinine Democrinus sp. or Monachocrinus sp. These taxa are all extant and suggest a minimum depositional depth for the Manchioneal Formation at this locality of about 180 m. This early Pleistocene fauna represents the most diverse assemblage of fossil crinoids docu mented from the Antillean region. Huit especes d’isocrinines de la periode du Cretace inferieur au Pleistocene de la Jamai'que ont ete documentees. Les nouvelles decouvertes comprennent un deuxieme specimen d’une espece du Miocene du nord central de la Jamai'que, auparavant consideree comme l’espece Diplocrinus, mais reclassifiee en tant que Teliocrinus? aux presentes. Le Teliocrinus existant est limite a l’ocean Indien, meme si on a releve des specimens du Miocene au Japon, ce qui est revelateur d’une distribution plus repandue au cours du Neogene. -

Predation, Resistance, and Escalation in Sessile Crinoids
Predation, resistance, and escalation in sessile crinoids by Valerie J. Syverson A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Geology) in the University of Michigan 2014 Doctoral Committee: Professor Tomasz K. Baumiller, Chair Professor Daniel C. Fisher Research Scientist Janice L. Pappas Professor Emeritus Gerald R. Smith Research Scientist Miriam L. Zelditch © Valerie J. Syverson, 2014 Dedication To Mark. “We shall swim out to that brooding reef in the sea and dive down through black abysses to Cyclopean and many-columned Y'ha-nthlei, and in that lair of the Deep Ones we shall dwell amidst wonder and glory for ever.” ii Acknowledgments I wish to thank my advisor and committee chair, Tom Baumiller, for his guidance in helping me to complete this work and develop a mature scientific perspective and for giving me the academic freedom to explore several fruitless ideas along the way. Many thanks are also due to my past and present labmates Alex Janevski and Kris Purens for their friendship, moral support, frequent and productive arguments, and shared efforts to understand the world. And to Meg Veitch, here’s hoping we have a chance to work together hereafter. My committee members Miriam Zelditch, Janice Pappas, Jerry Smith, and Dan Fisher have provided much useful feedback on how to improve both the research herein and my writing about it. Daniel Miller has been both a great supervisor and mentor and an inspiration to good scholarship. And to the other paleontology grad students and the rest of the department faculty, thank you for many interesting discussions and much enjoyable socializing over the last five years. -

Helgen^''~ and Greg W. Rouse^'^ "^School of Earth and Environmental Sciences, University of Adelaide, Adelaide, SA 5005 Australia. ^South Australian Museum, North Terrace, Adelaide, SA 5000 Australia. "^Corresponding author. Email: [email protected] Abstract. Aporometra Clark, 1938, which belongs to the monotypic Aporometridae, is a crinoid genus endemic to temperate Australian waters. It has been described as being 'viviparous' and is among the smallest of comatulids. The small size of specimens, and poor morphological justifications for specific diagnoses have created uncertainty over the number of species in the genus and their distributions. This study identified a suite of characters using data from scanning electron microscopy and mtDNA sequencing {COI and ND2) to assess the number of species of Aporometra. Specimens were obtained from museimis and collected from Western Australia, South Australia, Victoria and New South Wales. Type material was also examined when possible. Phylogenetic hypotheses were generated using maximum parsimony-based analyses of the separate and combined datasets. The results support the monophyly oí Aporometra and the presence of two species, Aporometra wilsoni (Bell, 1888) aaà Aporometra occidentalis A. H. Clark, 1938, along the southern Australian coast. The status of the third nominal species, Aporometra paedophora (H. L. Clark, 1909), remains to be resolved, but it may be a junior synonym of ^. wilsoni. Morphological diagnoses are reviewed. Aporometra occidentalis was only found in Western Australia, while A. wilsoni was found from Western Australia to Victoria. -

Clark, 1911), that was collected from Geoje Island, at a depth of 47 m. The species is characterized by a small disk, covered by numerous fine scales, small radial shields that are wider than long, a small stumpy hook at the distal end of the radial shield, two tooth papilla, two adoral shield spines, 2nd adoral shield spine longer than other, tapered dramatically toward dull tip, five arms with four proximal arm spines, and two tentacle scales. We also obtained a 657 bp sequence from COI gene and the amplified sequence matched the general DNA barcoding region. The NJ and ML phylogenetic analyses revealed A. (A.) digitula as monophyletic in the Amphiura clade. This species is clearly distinguished from other Amphiura species by morphological characteristics and the mitochondrial COI sequence, and thus represents the sixth Amphiura species reported to occur in Korea.
