  1. 1. 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.

    Sammanfattning : The dentine of teeth from five genera of mosasaurs [i.e., Clidastes, Halisaurus, Dollosaurus (Prognathodon),cf. Platecarpus, and Tylosaurus] and a Mesozoic crocodylian (Aigialosuchus) from the Campanian of the Kristianstad Basin, southernmost Sweden, displays two types of incremental growth lines; i. 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
