  1. 1. Diversity and Ecology of a Middle Campanian (Late Cretaceous) Marine Reptile Assemblage from Skåne, Southern Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lena Källsten; [2015]
    Nyckelord :Landmark morphometrics; Marine amniotes; Cretaceous; Mosasauridae; Plesiosauridae; Aigialosuchus; Landmärkesbaserad morfometri; marina amnioter; Kritaperioden; Mosasauridae; Plesiosauridae; Aigialosuchus;

    Sammanfattning : This study has looked at an assemblage of fossilised teeth from Mesozoic marine amniotes from the Kristianstad basin in southern Sweden in order to make an estimate of the ecomorph diversity within said assemblage through looking at the morphology of the teeth. This was done as a pilot study to see if further studies would be able to produce worthwhile results. LÄS MER

  3. 2. Long bone and vertebral microanatomy and osteo-histology of ’Platecarpus’ ptychodon (Reptilia, Mosasauridae) : implications for marine adaptations

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Miriam Heingård; [2014]
    Nyckelord :benhistologi; mikroanatomi; mosasaurier; akvatisk anpassning; tillväxthastighet; bone histology; bone microanatomy; mosasaurs; aquatic adaptations; growth rate; Earth and Environmental Sciences;

    Sammanfattning : The inner bone architecture and histology provide information about life history traits of extant as well as extinct animals. Mosasaurs (family Mosasauridae) are a group of secondarily adapted marine squamates that radiated in the Late Cretaceous, resulting in the evolution of a body plan adapted for pelagic habitats.

  4. 3. Bevarat maginnehåll hos mosasaurier

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ellen Jönsson; [2013]
    Nyckelord :gut content; Marlbrook-marlformationen; Mosasaurus; mosasaurier; maginnehåll; kololit; cololite; mosasaur; Marlbrook Marl Formation; Earth and Environmental Sciences;

    Sammanfattning : Relationen mellan bytesdjur och rovdjur i forntida ekosystem kan rekonstrueras med hjälp av olika fossil som t.ex. kololiter, det vill säga förstenat mag- och tarminnehåll. Mosasaurier (familjen Mosasauridae) är en grupp marina ödlor med världsvid utbredning under sen krittid. LÄS MER

    Sammanfattning : Marine strata of latest early Campanian age from the Kristianstad Basin in Skåne, southern Sweden, have yielded a diverse mosasaur fauna comprising four taxa: Clidastes? sp., Platecarpus cf. somenensis, Hainosaurus? ivoensis and Mosasauridae sp. LÄS MER
