Marsden Medal in 2026 by the Linnean Society for the best doctoral thesis in biology outside the field of botany.<\/p>\n<p><!-- \/wp:image --><!-- wp:paragraph --><\/p>\n<p>The award recognizes a 2025 study published in the Zoological Journal of the Linnean Society, which presented key findings from her doctoral research. Roese-Miron investigated the cynodont Siriusgnathus niemeyerorum, a prehistoric vertebrate belonging to the ancestral lineage of mammals that lived more than 200 million years ago during the Triassic Period in southern Brazil.<\/p>\n<p><!-- \/wp:paragraph --><!-- wp:paragraph --><\/p>\n<p>By utilizing high-resolution computed tomography (CT scanning), the research team conducted a detailed analysis of a complete skull specimen. This advanced digital approach enabled the reconstruction of internal anatomical structures, including the inner ear and the pathways previously occupied by cranial nerves. The findings also revealed new insights into the animal&#8217;s facial mobility, offering a clearer understanding of behaviors such as feeding, defense, and social interaction in these extinct mammal ancestors.\u00a0 \u00a0 \u00a0<\/p>\n<p>\u00a0<\/p>\n<figure style=\"width: 536px\" class=\"wp-caption alignleft\"><img decoding=\"async\" class=\"\" src=\"https:\/\/www.ufsm.br\/app\/uploads\/2026\/05\/Imagem-1.jpg\" alt=\"\" width=\"536\" height=\"410\" \/><figcaption class=\"wp-caption-text\">Skull details of Siriusgnathus niemeyerorum<\/figcaption><\/figure>\n<p><!-- \/wp:gallery --><!-- wp:paragraph --><\/p>\n<figure style=\"width: 470px\" class=\"wp-caption alignright\"><img decoding=\"async\" class=\"\" src=\"https:\/\/www.ufsm.br\/app\/uploads\/2026\/05\/Imagem-2.jpg\" alt=\"\" width=\"470\" height=\"394\" \/><figcaption class=\"wp-caption-text\">Details of the internal cranial anatomy of Siriusgnathus niemeyerorum<\/figcaption><\/figure>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<p>\u201cI am deeply honored to receive this award.
