    Abstract : In 1999 a Kimmeridgian age vertebra of a sauropod dinosaur was discovered directly in a layer of clays from Cricqueboeuf in Normandy, France. The vertebra is now located at the Paleospace museum and was part of an inventory in 2015 as well as the subject of this Master thesis. READ MORE

  3. 2. The population structure of Late Pliocene and Early Pleistocene Neptunea angulata, Gastropoda and an investigation into bias in the fossil record and museum collections.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Thomas Owen; [2016]
    Keywords : Bias; age distributions; taphonomy; population structure.; Partiskhet; åldersfördelning; tafonomi; populationsstrukturer.;

    Abstract : The fossil population structure of the gastropod Neptunea angulata from the late Pliocene and Early Pleistocene was investigated in this project in order to contribute to a wider study on the influence of predation on populations and the evolutionary history of organisms. Over time, predator-prey relationships can drive evolution in a way similar to the Red Queen Hypothesis. READ MORE

  4. 3. An Investigation into Predation, Mortality and Taphonomic Bias inthe Population Distribution of Neptunea contraria from theRed Crag of East Anglia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alexander Seale; [2016]
    Keywords : Predation; taphonomy; sampling bias; palaeobiology; gastropods; population distribution; Predation; tafonomi; provtagning snedhet; paleobiologi; snäckor; populationsfördelning;

    Abstract : Predation is a key factor in evolutionary dynamics. It disrupts the potential of fossilisation in prey items and is poorly recorded in the fossil record; failed predation in conical marine gastropods is recorded in scars. READ MORE
