1. 1. Estimating the Early Evolution of Brachiopods Using an Integrated Approach Combining Genomics and Fossils

   University essay from Uppsala universitet/Paleobiologi

   Author : Chloé Robert; [2019]
   Keywords : Brachiopoda; evolutionary history; phylogeny; Maximum likelihood; Bayesian inference; fossil calibrations; Brachiopoda; evolutionhistoria; fylogeni; Maximum likelihood-metoden; Bayesiansk statistik; fossilkalibering;

   Abstract : The Brachiopoda, a major group of the Lophotrochozoa, experienced a rapid early evolutionary diversification during the well-known Cambrian explosion and subsequently dominated the Palaeozoic benthos with its diversity and abundance. Even though the phylogeny of the Lophotrochozoa is still hotly debated, it is now known that the Brachiopoda are a monophyletic grouping. READ MORE

   Abstract : A new locality of the Alum Shale Formation at Björnberget, Västerbotten County, of the lower allochthon of the Caledonian front is described herein. Two new species of acrotretid brachiopods were found. Tingitanella vilhelminia n. sp. READ MORE

4. 3. Linguliform Brachiopods from the Middle Cambrian ‘Thick’ Stephen Formation at Odaray Mountain, Canadian Rocky Mountains

   Author : Sara Saxén; [2015]
   Keywords : Brachiopoda; Lingulida; Middle Cambrian; Stephen Formation; new species; Brachiopoda; Lingulida; Mellersta kambrium; Stephenformationen; ny art;

   Abstract : The linguliform brachiopod fauna from the Stephen Formation have long been thought to be very species poor and only consist of a few genera, but new discoveries from lime-stone beds in the “thick” Stephen Formation shows that this is not the case. The species described herein, Kyrshabaktella cf. tatjanae and Ceratreta hansi sp. nov. READ MORE

5. 4. 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

6. 5. Paleoecology and sedimentology of the Upper Cretaceous (Campanian), marine strata at Åsen, Kristianstad Basin, Southern Sweden, Scania

   University essay from Lunds universitet/Geologiska institutionen

   Abstract : The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. READ MORE
