Phylogenetic Analysis of Early Ornithosuchian Archosaurs

鸟鳄类（鸟鳄类） 在陆地生态系统中存在了2亿多年， 以9,000种鸟类的形式继续这样做。 但我们对鸟类的早期进化知之甚少 主龙 这笔赠款将使更全面的 这个问题的调查比迄今为止还可能。 更清楚地了解土著人民之间的家谱关系 早期鸟鳄类将作为评估主要 它们进化史的各个方面。

Bird-archosaurs (the Ornithosuchia) have played major roles in terrestrial ecosystems for over 200 million years, and they continue to do so in the form of 9,000 living species of birds. But very little is known of the early evolution of bird- archosaurs. This grant will enable a more comprehensive investigation of this problem than has yet been possible. Clearer understanding of genealogical relationships among the early ornithosuchians will serve as a basis for evaluating major aspects of their evolutionary history.
