This study shows that camptotrichia constitute the only skeleton of the Dipnoan fins. Their fine structure is indeed quite different from the two other Osteichthyan dermotrichia, namely the actinotrichia and the lepidotrichia found simultaneously in the fin margin of both Actinopterygians and Crossopterygians fins. Although different from lepidotrichial bone, the fine structure of camptotrichia is more reminiscent of it than of the elastoidin-formed actinotrichia.
本研究表明,弯角鳍条构成了肺鱼鳍的唯一骨架。它们的精细结构确实与其他两种硬骨鱼皮鳍条有很大不同,即同时存在于辐鳍鱼类和肉鳍鱼类鳍边缘的鳍条骨和鳞质鳍条。尽管弯角鳍条与鳞质鳍条骨不同,但其精细结构更类似于鳞质鳍条骨,而非由弹性蛋白形成的鳍条骨。
