- The optimum biostratigraphic sequence was established. Ten fossil assemblage zones (RASC zones, in term of RASC distance) were identified, and regional geological time table was set up, which shows the relationship between age, strata, and RASC zones. 根据化石事件间的 RASC 距离,将这个最佳序列划出10个化石组合带,用 CASC 方法建立了区域地质年表,展示了地质年代、地层和RASC 分带之间的关系,并完成了井间对比。
- What is more, the Malagasy fossil assemblage lacks remains of several younger reptile groups usually found with the earliest dinosaurs, including the heavily armored, crocodilelike phytosaurs and aetosaurs. 此外，马达加斯加的化石组合中，缺乏爬行类比较年轻的种类，例如形似鳄鱼的植龙与鹫龙，身体都有厚重的甲胄保护，通常与早期恐龙一齐出土。
