Morphological Diversification and Classification of the Crinoidea

9404752 Ausich Pi将试图描绘寒武纪至奥陶纪(约4.5亿-5亿年前)海百合(海百合)早期历史上海百合(海百合)形态多样化的主要方面。海百合是整个古生代最重要的海洋生物之一，至今仍生活在海洋中。PI还将构建鹦鹉总科的系统发育分类，并确定进化趋势，在群落生态学的背景下解决多样性问题。

9404752 Ausich PI will attempt to delineate major aspects of the morphological diversification of the Crinoidea (crinoids) during their early history in Cambrian to Ordovician time (c. 450-500 million years ago). Crinoids were among the most important marine organisms throughout the Paleozoic, and are still living in today's oceans. PI will also construct a phylogenetic classification of the Crinoidea, and identify evolutionary trends, addressing diversification in a context of community ecology.
