9321726 Rigby Despite more than 80 years of research on the renowned Permian "reef" complex of the Delaware Basin (New Mexico/West Texas), there have been no detailed studies of the very abundant sponges in this bioherm. PIs will a) identify and describe the sponges to species level and interpret their phylogenetic significance; 2) assess the biostratigraphic value of these species and evaluate effects of the Permo-Triassic mass extinction on this group of sponges; 3) address paleobiogeographic issues with respect to these sponges; and 4) conduct a paleoecologic analysis of the algal-sponge community.

9321726里格比尽管对特拉华州盆地（新墨西哥州/西德克萨斯州）著名的二叠纪“礁”复合体进行了80多年的研究，但还没有对该生物礁中非常丰富的海绵进行详细研究。 PI将a）识别和描述海绵物种水平，并解释其系统发育意义; 2）评估这些物种的生物地层学价值，并评估二叠纪-三叠纪大灭绝对这组海绵的影响; 3）解决这些海绵的古生物地理问题; 4）对藻类海绵群落进行古生态学分析。
