  1. 1. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joseph Asanbe; [2022]
    Keywords : late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Abstract : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. READ MORE

  2. 2. Echo of the Ancients: Evolution of Song in the Avian Family Cettiidae

    University essay from Uppsala universitet/Paleobiologi

    Author : Jared Goodstadt; [2022]
    Keywords : Cettiidae; song; acoustic analysis; PCA; Mahalanobis distance; phylogeny;

    Abstract : The Cettiidae, a family of primarily small, insectivorous, Asiatic and Austronesian, mountain birds have been the subject of acoustic analysis in the past. However, until this point, an in-depth review of the songs of the entire family had yet to be undertaken. READ MORE

  3. 3. Understanding the impact of the superplume in Eastern Africa during the Miocene on regional climate in EC-Earth simulations.

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Eduardo Toledo Romero; [2020]
    Keywords : ;

    Abstract : This project attempts to gather more information to link the rise in the topography during the Miocene in Eastern Africa with climate changes that lead to the aridification of the area and ultimately to the split between chimpanzees and hominids. The candidate analysed a series of sensitivity experiments simulated with a climate model EC-Earth by changing the topography in Easter Africa and comparing with control run (pre-industrial-era) to assess the impact of the changes in the superplume in Africa and consequent topography on the climate and environment.

  4. 4. Relating early Human evolution to late Miocene - early Pliocene climate change

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tika van Galen; [2020]
    Keywords : climate; evolution; climate change; hominins; bipedal locomotion; late Miocene; Pliocene;

    Abstract : Human evolution has been linked to climate change multiple times in the literature. One of the more well-known theories is the ‘savannah’ theory, which states that walking upright became an advantageous character when climate in Africa changed causing drier environments, changing woodlands to savannahs.

  5. 5. The Neurocranium of Anasinopa leakeyi (Hyaenodonta, Mammalia) – a First Insight into Teratodontine Brain Morphology

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Therese Flink; [2019]
    Keywords : Africa; Hyaenodonta; Miocene; neurocranium; palaeoneurology; Teratodontinae; Afrika; Hyaenodonta; Miocene; neurokranium; palaeoneurologi; Teratodontinae;

    Abstract : The Hyaenodonta include a wide variety of carnivorous mammals ranging in age from late Palaeocene to middle Miocene. Although they reached a nearly global distribution, little remains of them today. Many of the taxa are based only on teeth and jaw fragments. READ MORE
