Problem Set 6 – Discourse Foundations of Linguistics WS 2018/19 Scheffler Problem Set 6 – Discourse [due January 29, 2019] Exercise 1: Centering. Do a Centering analysis of the following two texts (specify Cf, Cb, Cp, and the transition for each utterance). Are there any theoretical arguments for why one text is better than the other? Do you agree with the prediction? (Note: only include specific referential entities, i.e., John, the store, in your analysis) (1) a. John went to a music store to buy a piano. b. It was a store that John had been going to for years. c. He was happy that he could finally buy a piano. d. The store was just closing when John arrived. (2) a. John went to a music store to buy a piano. b. He had been shopping at the store for years. c. He was happy that he could finally buy a piano. d. When he arrived, the store was just closing. Can you change (1d) to violate the pronominalization rule? Exercise 2: Connectives. Find the explicit and implicit connectives in the following text. Identify their arguments. (Remember not to posit any discourse relations across paragraph breaks.) You can call it a Triassic titan. Or a pre-Jurassic juggernaut. Just don’t call it a dinosaur. Despite its appearance, this burly behemoth was a completely different prehistoric beast: a dicynodont. Early relatives to present-day mammals, dicynodonts dominated Earth more than 200 million years ago, living first before, and then alongside, dinosaurs. Unlike dinosaurs, these herbivorous animals had short necks and large skulls. They were stocky like rhinos, toothless and had tusks and turtle-like beaks. Many ranged in sizes from pigs to hippos, though some were small enough to burrow into the ground. Now, scientists have uncovered a new species of dicynodont that towered over the rest, comparable in size to an elephant. The newly discovered species, known as Lisowicia bojani, was 8.5 feet tall and about 15 feet long, and weighed 9 tons. It is both the largest and youngest dicynodont found so far and its discovery provides further evidence that these proto-mammals survived into the late Triassic Period, past the point when many scientists had previously thought they went extinct. .

    Triassic pentadactyl tracks from the Los Menucos Group (Río Negro province, Patagonia Argentina): possible constraints on the autopodial posture of Gondwanan trackmakers Paolo Citton1,2, Ignacio Díaz-Martínez1,2, Silvina de Valais1,2 and Carlos Cónsole-Gonella1,3 1 Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Buenos Aires, Argentina 2 Instituto de Investigación en Paleobiología y Geología (IIPG), Universidad Nacional de Río Negro, General Roca, Argentina 3 Instituto Superior de Correlación Geológica (INSUGEO), Universidad Nacional de Tucumán, Tucumán, Argentina ABSTRACT The Los Menucos locality in Patagonia, Argentina, bears a well-known ichnofauna mostly documented by small therapsid footprints. Within this ichnofauna, large pentadactyl footprints are also represented but to date were relatively underinvestigated. These footprints are here analyzed and discussed based on palaeobiological indications (i.e., trackmaker identification). High resolution digital photogrammetry method was performed to achieve a more objective representation of footprint three-dimensional morphologies. The footprints under study are compared with Pentasauropus from the Upper Triassic lower Elliot Formation (Stormberg Group) of the Karoo Basin (Lesotho, southern Africa). Some track features suggest a therapsid-grade synapsid as the potential trackmaker, to be sought among anomodont dicynodonts (probably Kannemeyeriiformes).

Herbivory 1234567890():,; evolved independently several times as ecosystems comprising diverse assemblages of therapsids, parareptiles and archosauromorphs rose and fell, leading to a world dominated by dinosaurs. It was assumed that dinosaurs prevailed either through long-term competitive replacement of the incumbent clades or rapidly and opportunistically following one or more extinction events. Here we use functional morphology and ecology to explore herbivore morphospace through the Triassic and Early Jurassic. We identify five main herbivore guilds (ingestion generalists, prehension specialists, durophagous specialists, shearing pulpers, and heavy oral processors), and find that herbivore clades generally avoided competition by almost exclusively occupying different guilds. Major ecosystem remodelling was triggered multiple times by external environmental challenges, and previously dominant herbivores were marginalised by newly emerging forms. Dinosaur dominance was a mix of opportunity following disaster, combined with competitive advantage in their new world. 1 School of Earth Sciences, University of Bristol, Bristol, UK. ✉email: [email protected] NATURE COMMUNICATIONS | (2021) 12:2796 | https://doi.org/10.1038/s41467-021-23169-x | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-021-23169-x errestrial ecosystems underwent significant remodelling Results and discussion Tduring the Triassic via floral and faunal turnovers that Triassic herbivore ecomorphological feeding guilds.

SIDOR,*,1 1Department of Biology and Burke Museum, University of Washington, Seattle, Washington 98195, U.S.A., [email protected], [email protected], [email protected] *Corresponding author RH: MARILAO ET AL.—DICYNODONT PREPARIETAL HISTOLOGY Marilao, Kulik, Sidor 2 ABSTRACT—The preparietal, a neomorphic midline ossification on the skull roof, is thought to have evolved three times in therapsids, but its development and homology remain poorly understood. Here we provide preliminary data on the histology of this element in specimens referred to Diictodon feliceps and an indeterminate species of Lystrosaurus. The preparietal has previously been noted to vary substantially in its shape on the dorsal surface of the skull in several dicynodonts and we found similar variation in thin section. In Diictodon, the preparietal forms a prong that embeds itself entirely within the frontals and shows evidence of a midline suture anteriorly. The sectioned specimen of Lystrosaurus shows histological evidence of immaturity and features a well-defined midline suture at the posterior end of the preparietal, although an anterior prong was not present. In both taxa the anteroventral portion of the preparietal forms a strongly interdigitating suture with the underlying frontals and parietals. More posteriorly, the preparietal is composed of fibrolamellar bone suggestive of rapid posteroventral growth. In large dicynodont species, the dorsal expression of the preparietal appears to show negative allometry compared to other cranial roofing elements during ontogeny, but the significance of this geometry is unclear.

  • Unusual Tusks in a New Species of Dicynodont from the Permian of Brazil 26 May 2016, by Sarah Gibson
    Unusual tusks in a new species of dicynodont from the Permian of Brazil 26 May 2016, by Sarah Gibson organisms is recorded from the Beaufort Group of South Africa, but the record from Brazil has been less extensive, with only one Permian-age specimen (Endothiodon) previously recorded from the Paraná Basin, and three genera from the Triassic. This new species, dubbed Rastodon procurvidens by the authors, is now the second known taxon from the Permian of Brazil. The description is based on a single specimen, but a beautiful one at that, with an almost complete skull and lower jaws. It was collected on a private farm in Rio Grande do Sul, from the Guadalupian/Lopingian Rio de Rasto Formation. The skull is slightly crushed dorsoventrally, but is still so well preserved that it is The skull of Rastodon procurvidens, holotype easy to distinguish characteristics that define it as a UNIPAMPA PV147P. Credit: Felipe Lima Pinheiro dicynodont. May has been a spectacularly busy month. And a lot of awesome research was recently published on PLOS ONE and other open access journals (check out our Fossil Friday Roundup feature for lists of the latest publications and news) while I was out traversing across the state of Utah (looking at fish fossils and dinosaur tracks – more on that later!). But now that I've returned from traveling (for now), and Fossil Friday Roundup is successfully off and running, I'm back and ready to share with you the latest paper, published today in PLOS ONE. The study, by authors Alessandra Boos, Christian Kammerer, Cesar Schultz, Marina Soares, and Ana Ilha, examines a beautifully preserved dicynodont skull from the Permian of Brazil, and Phylogenetic position of Rastodon procurvidens within Dicynodontia based on the results of the phylogenetic with this skull comes a lot of new information and analysis.

SURKOV1, NIKOLAS N. KALANDADZE2, and MICHAEL J. BENTON3 1Geology Institute of Saratov University, Astrakhanskaya 83 st., 410075 Saratov, Russia, [email protected] 2 Paleontologicheskii Institut, Profsoyuznaya 123, 117647 Moscow, Russia. 3Department of Earth Sciences, University of Bristol, Bristol, BS8 1RJ, U.K., [email protected] ABSTRACT—The postcranial skeleton of Lystrosaurus georgi from the lowermost Triassic of the Moscow Basin, Russia, is described for the first time. This species retains contact between the premaxillae and palatine and is characterized by a narrow and elongated ischium, an autapomorphy for this species. Phylogenetic analysis of 27 Permian and Triassic dicynodont taxa using 18 postcranial characters confirms other recent hypotheses, but does not support a close relation- ship between Cistecephalus and Kingoria. The low homoplasy level among characters of the pelvis and femur, compared with the shoulder girdle and forelimbs, suggests that the former region documents the pattern of anomodont evolution better than the latter. Analysis of character changes revealed that a general evolutionary trend in the dicynodont postcranium relates to acquisition of semisprawling locomotion.
