  1. 1. Estimating the Early Evolution of Brachiopods Using an Integrated Approach Combining Genomics and Fossils

    University essay from Uppsala universitet/Paleobiologi

    Author : Chloé Robert; [2019]
    Keywords : Brachiopoda; evolutionary history; phylogeny; Maximum likelihood; Bayesian inference; fossil calibrations; Brachiopoda; evolutionhistoria; fylogeni; Maximum likelihood-metoden; Bayesiansk statistik; fossilkalibering;

    Abstract : The Brachiopoda, a major group of the Lophotrochozoa, experienced a rapid early evolutionary diversification during the well-known Cambrian explosion and subsequently dominated the Palaeozoic benthos with its diversity and abundance. Even though the phylogeny of the Lophotrochozoa is still hotly debated, it is now known that the Brachiopoda are a monophyletic grouping. READ MORE

  2. 2. Cell Size Variation in Fossil Coccolithophores (Haptophyta) : A Study of Pliocene Sediments from Northwestern Australia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nicole Eliassen; [2018]
    Keywords : Coccolithophore; cell; carbon cycle; Australia; palaeobiology; climate change.; Fästalger Haptophyta ; kokkolitoforider; Pliocen; cell; kolcykel; Australien; paleobiologi; klimatförändring;

    Abstract : This report examines the size variations of fossil carbonate-producing haptophyte microalgae, coccolithophores, using sediments deposited during the Pliocene. The sediments were collected by the International Ocean Discovery Program (IODP) in 2015, off the coast of NW Australia (Gallagher et al., 2017). READ MORE

  3. 3. The Importance of Curation: a Case-Study of the Subfossil Lemur Collection in the Museum of Evolution, Uppsala University

    University essay from Uppsala universitet/Paleobiologi

    Author : Maria Lindkvist; [2016]
    Keywords : curation; collection management; subfossil lemurs; Bertil Ljungqvist; Museum of Evolution; kurering; samlingsvård; subfossila lemurer; Bertil Ljungqvist; Evolutionsmuseet;

    Abstract : In times when many natural history museums experience financial cuts, it is important to show why museums matter, what they can offer, and what they mean for both the public and the scientific society. The collections are the heart of the museum and they need to be well-managed in order to attract visitors (both researchers and public). READ MORE

  4. 4. An Investigation into Predation, Mortality and Taphonomic Bias inthe Population Distribution of Neptunea contraria from theRed Crag of East Anglia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexander Seale; [2016]
    Keywords : Predation; taphonomy; sampling bias; palaeobiology; gastropods; population distribution; Predation; tafonomi; provtagning snedhet; paleobiologi; snäckor; populationsfördelning;

    Abstract : Predation is a key factor in evolutionary dynamics. It disrupts the potential of fossilisation in prey items and is poorly recorded in the fossil record; failed predation in conical marine gastropods is recorded in scars. READ MORE

  5. 5. The Primitive Antiarch Yunnanolepis from China : A Microtomographic Study

    University essay from Uppsala universitet/Paleobiologi

    Author : Jessica Grahn; [2016]
    Keywords : placodermi; microtomography; 3D model; mikrotomografi; 3D-modell;

    Abstract : Placoderms appeared in the Silurian period and rapidly evolved and dominated the waters during the Devonian period. Among the earliest of the placoderms are yunnanolepids, a primitive form of antiarch from the Early Devonian of China and Vietnam. READ MORE
