This paper briefly reviews the Triassic marine reptile fossils in Guizhou Province, especially the fossils that have been recently found in the Guanling area. Based on three sections at Guanling and Xingyi, Guizhou Province and Luoping, Yunnan Province, four horizons with vertebrate fossils are recognized in the Middle and Upper Triassic of this area; They are from bottom to top: Member I and Member II of the Guanling Formation, and the Zhuganpo Member and the Wayao Member of the Falang Formation.  相似文献

Buchanosteus(节甲鱼类)的新材料及其生物地层学意义     

王俊卿 《地质通报》2005,24(9):800-806

记述了采自广西永福附近泥盆系的一鱼类化石标本。根据头甲轮廓和内颅特征，将其归入节甲鱼类。头甲的宽度大于后松果区长度，中颈片为梯形，后边缘片有较长的后突。内颅吻囊与筛后一枕区分开，耳区短；前眶后突不明显，位置靠后；后眶后突明显，远端不分叉。因此新材料应归入巴坎鱼属（Buchanosteus）。但眼孔大并朝向背侧上方，骨片上粒状突起纹饰的冠部和基部没有星状嵴等特征与Buchanosteus confertituberculatus（Chapman）不同，所以新材料应代表一新种，即Buchanosteus兴guangxiensis sp．nov．。还对澳大利亚与中国华南地区当时的古地理关系进行了讨论。  相似文献
