Paleontology Geology This dissertation includes eight chapters, each of which are contributions pertaining to the systematics and morphology of crustaceans, primarily Paleozoic malacostracans, but also some Jurassic isopods, and Silurian ostracods. Chapters 3–6 focus on Paleozoic eumalacostracan taxa exhibiting gross similarity to decapod crustaceans. Chapter 3 focuses on the description of Devonostenopus pennsylvaniensis, the first described Paleozoic stenopodid, and only the third described Devonian decapod. Chapter 4 focuses on the description of a new genus and species of pygocephalomorph peracarid exhibiting remarkable similarity in carapace morphology to early higher brachyurans. Chapter 5 is a re-evaluation of the systematic position of tealliocarid eumalacostracans, in which it is asserted that tealliocarids are not only peracarids, but should be included in the apparently monophyletic taxon Pygocephalomorpha, as has historically been the case. Chapter 6 is a re-evaluation of the morphology and systematic position of Palaeopalaemon newberryi, a species that has for some time been considered to be a decapod crustacean. In addition to new morphological aspects Palaeopalaemon newberryi being described, the systematic position of that species as a decapod is supported with testing in a rigorous phylogenetic framework.Chapters 7–9 focus on the systematics and morphology of primarily Silurian crustaceans, including ceratiocarid phyllocarids, and leperditicopid ostracods. In chapter 7, the systematics and taphonomy of the phyllocarids from the Silurian Waukesha Biota of Wisconsin are evaluated. Three species of Ceratiocaris, C. macroura, C. papilio, and C. pusilla are recognized. Preservation of soft-bodied arthropods from the Waukesha Biota is thought to be due to progressive burial and phosphatization, slightly above the dysoxic-anoxic boundary. Chapter 8 was an evaluation of antennular and antennal morphology in archaeostracan phyllocarid crustaceans. It was proposed that retention of two elongated flagella in both the antennule and antenna represents the plesiomorphic condition in malacostracan crustaceans. Ceratiocarid phyllocarids may represent stem-lineage eumalacostracans, based on the presence of a scale-like antennal exopod. Chapter 9 focuses on the systematics and morphology of Dihogmochilina boothia, the most common ostracod occurring in the Waukesha biota. Exceptionally preserved soft-parts, including trunk outlines, thoracic appendages, in situ broods, and a hemolymph system are recognized. Based on the presence of a hemolymph system, evidence of maternal care, and a flagelliform seventh appendage, Leperditicopida is changed in rank to the suborder Leperditicopina, and transferred to Myodocopida.Chapter 10 is a systematic evaluation of the isopods from the Jurassic Plattenkalk biota of Monte Fallano, Italy. Three new isopod species, Palaega furcillanatis, Archaeoniscus italiensis, and Sphaeroma montefallanoense are described. Additionally, the second occurrence of Niveotanais brunnensis, a niveotanaid anthracocaridomorph tanaidacean is reported from the Jurassic of Italy, suggesting that niveotanaids represent the last vestige of the survival of the primarily Paleozoic anthracocaridomorphs into the Mesozoic. The presence of a preserved tanaidacean also permits inference about the paleoenvironmental conditions under which the biota was deposited. Chapter 11 is the conclusion of the dissertation, and a summary of the results contained herein. 2016-08-02 English text Kent State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=kent1469705886 http://rave.ohiolink.edu/etdc/view?acc_num=kent1469705886 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
