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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Geologiska institutionen

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

   Abstract : 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. Upper Cretaceous coprolites from the Münster Basin (northwestern Germany) : a glimpse into the diet of extinct animals

   University essay from Lunds universitet/Geologiska institutionen

   Author : Stavros Anagnostakis; [2013]
   Keywords : koproliter; carnivorous vertebrates; Germany; Münster Basin; Coprolites; Upper Cretaceous; sen krita; Münsterbassängen; Tyskland; rovlevande vertebrater; Earth and Environmental Sciences;

   Abstract : En omfattande samling koproliter från tre lokaler med sediment från sen kritatid i Münsterbassängen (nordvästra Tyskland) har studerats med en mängd olika analytiska tekniker med avsikten att belysa urtida trofiska nivåer och relationen mellan rovdjur och bytesdjur. Den fosfatiska sammansättningen, inneslutningar av benmaterial, storlek och form tyder på att de flesta eller samtliga koproliter producerades av rovlevande vertebrater. READ MORE

5. 4. Dental histology of Cretaceous mosasaurs (Reptilia, Squamata) : incremental growth lines in dentine and implications for tooth replacement

   University essay from Lunds universitet/Geologiska institutionen

   Author : Johan Gren; [2011]
   Keywords : dental histology; mosasaurs; Cretaceous tetrapods; incremental lines; von Ebner; Andresen; tooth replacement; tandhistologi; mosasaurier; kretaceiska tetrapoder; tillväxtlinjer; tandersättning; Earth and Environmental Sciences;

   Abstract : 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.

6. 5. Late Cretaceous coprolites from the Kristianstad Basin, southern Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Urban Månsby; [2009]
   Keywords : coprolites; Cretaceous; Kristianstad; Åsen; spiral; koproliter; krita; spiralformade; Earth and Environmental Sciences;

   Abstract : Vertebrate coprolites from the Upper Cretaceous (Campanian) of the Åsen locality, Kristianstad Basin, southern Sweden, are described and illustrated. Their fecal origin was supported through chemical analyses revealing a calcium phosphate composition. READ MORE
