| 摘 要： | 依据在云南富源中三叠世法郎组竹杆坡段发现的新材料,对关岭贵州空棘鱼(Guizhoucoelacanthus guanlingensis)进行了补充描述,并修订了鼻骨、顶骨、后顶骨、额外肩胛骨、眶后骨、偶鳍、鳞片等特征。系统发育分析表明,贵州空棘鱼属与Whiteia+Piveteauia构成姐妹群,其共有离征包括:两对顶骨的大小相近,第一背鳍鳍条数小于8。建议将贵州空棘鱼属归入怀特鱼科(Whiteiidae)。

| Abstract: | We re-describe the coelacanth Guizhoucoelacanthus guanlingensis Liu et al.,2006,mainly based on a new articulated specimen from the Middle Triassic of Fuyuan,Yunnan Province,China.It is characterized by its small orbital openings,and the postorbital spanning the intracranial joint.The phylogenetic analysis suggests that Guizhoucoelacanthus is the sister taxon of Whiteia+Piveteauia. Guizhoucoelacanthus is assigned to the family Whiteiidae with derived characters including:anterior and posterior pairs of pari... |
