  1. 16. 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

    Abstract : I mellersta ordovicium var inflödet av kosmiskt material till jorden högre än idag, i sviter-na efter uppbrytningen av den L-kondritiska asteroidkroppen i asteroidbältet mellan Mars och Jupiter, vilket beri-kade den forna havsbottnen med meteoriter och kosmiskt damm. Komstadformationen i Killeröd, Skåne, innehåller ett lager särskilt rikt på L-kondritiska kromitkorn vilket indikerar en hög grad av kondensation. READ MORE
