Hain<\/p>\n<p>High-resolution X-ray microtomography methods have helped evolutionary biology (a team led by Prof. Klembara) to solve the problem existing over a century, related to the origin of amniotes and thus an essential stage in vertebrate evolution. This stage of evolution is important because the tetrapods broke their ties with the aquatic environment and began to settle the land. Two groups of early tetrapods and ancestors of amniotes \u2013 the fossil findings of representatives of diadectomorphs and seymouriamorphs \u2013 were analysed by X-ray microtomography, namely their labyrinth of the inner ear. Acquired 3D data from microCT measurements were then subjected to mathematical processing and time-consuming data segmentation with the goal to distinguish fossil structures from the sediment. The results were finally subjected to a cladistic analysis and provided paleobiologists with the knowledge to determine the new classification of these groups in the developmental cladogram.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Result applicator:<\/strong><\/p>\n<p>Pr\u00edrodovedeck\u00e1 fakulta UK<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-933 aligncenter\" src=\"https:\/\/www.um.sav.sk\/en\/wp-content\/uploads\/sites\/2\/2019_aplikacny-typ-1-247x300.jpg\" alt=\"\" width=\"362\" height=\"439\" srcset=\"https:\/\/www.um.sav.sk\/en\/wp-content\/uploads\/sites\/2\/2019_aplikacny-typ-1-247x300.jpg 247w, https:\/\/www.um.sav.sk\/en\/wp-content\/uploads\/sites\/2\/2019_aplikacny-typ-1-82x100.jpg 82w, https:\/\/www.um.sav.sk\/en\/wp-content\/uploads\/sites\/2\/2019_aplikacny-typ-1.jpg 686w\" sizes=\"auto, (max-width: 362px) 100vw, 362px\" \/><\/p>\n<p><em><strong>Fig.:<\/strong> Fossilised skull of Diadectes absitus and microtomographic virtual 3D reconstruction of inner ear structures<\/em><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Publications:<\/strong><\/p>\n<ol>\n<li>KLEMBARA, J. \u2013 HAIN, Miroslav \u2013 RUTA, M. \u2013 BERMAN, D.S. \u2013 PIERCE, S.E. \u2013 HENRICI, A.C.
