  1. 1. Palaeoenvironments of the Earliest (Middle Devonian) Tetrapod Trackways from the Holy Cross Mountains, Poland; Locomotion in a Terrestrial Setting?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Martin Qvarnström; [2015]
    Keywords : Tetrapods; palaeoenvironment; trackways; paleosols; microfacies; trace fossils; fin-limb transition; Holy Cross Mountains.;

    Abstract : The palaeoenvironment from which early tetrapods emerged is crucial to comprehend in order to understand the mechanisms that drove and allowed the terrestrialization of vertebrates; one of the most important evolutionary ‘events’ in the history of animals. Nevertheless, much of the terrestrialization is shrouded in obscurity, inter alia, due to scarcity of early tetrapods in the fossil record. READ MORE

  3. 2. A Multi-Evidence Approach to the Affinity of Tylodus deltoides Rohon 1893

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Thomas Claybourn; [2015]
    Keywords : 3D virtual palaeohistology; evolution; Silurian; Gnathostomata; Holocephali; Ohesaare; 3D-virtuell paleohistologi; evolution; Silur; Gnathostomata; Holocephali; Ohesaare;

    Abstract : Early gnathostome evolution has recently undergone revision due to newly published phylogenies. Within this new framework, early gnathostomes in the fossil record can be revised, particularly the subject of this paper Tylodus deltoides (Rohon, 1893), vertebrate microremains from the Silurian Ohesaare Formation of Estonia.
