1. Body patterning and cognition in cephalopods - a literature review
Master-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : Cephalopods are a valuable model for studying the evolution of cognition due to their distinctive brain structure, organisation, and connectivity patterns compared to vertebrates. The development of large brains and behavioural complexities are believed to be triggered by evolutionary pressures stemming from factors like heightened predation, more demanding foraging conditions, and intense mating competition.

2. The evolutionary origins of consciousness
Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Some unanswered questions about consciousness as a biological phenomenon lie in its evolutionary origin and distribution among living organisms. Which animals are conscious and when did consciousness appear in the history of life on earth? The purpose of this thesis is to shed light on these long-standing questions by reviewing the literature on the evolutionary approaches to the fundamental concept of phenomenal consciousness. LÄS MER
3. Testing the Cretaceous Diversity of Ichthyosaurs and Their Extinction Hypotheses Using a Quantitative Approach
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : As portrayed in Before the Dinosaur: the Historical Significance of the Fossil Marine Reptiles, ichthyosaurs, as other Mesozoic marine amniotes, have been unfairly overshadowed by dinosaurs in both popular culture and the field of vertebrate palaeontology. Yet by the effort of dedicated researchers, work on these fish-like marine reptiles had never died out, and in fact a second wave of interest emerged in the late 20th century. LÄS MER
4. Bevarat maginnehåll hos mosasaurier
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : 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
5. Five new cephalopod species from the Silurian of Gotland
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Silurian oncocerid cephalopods, collected by Gustaf Lindström’s and co-workers at the end of the 19th century on the island of Gotland are described. The material is from the Samsugns quarries and found within large thanatocoenoses in the Wenlock Slite Beds. LÄS MER
