Abstract
Abstract. The multi-element apparatus of the Middle Triassic conodont
Neogondolella ex gr. regalis has been reconstructed based
on material collected from the upper Anisian in British Columbia, Canada. The
apparatus of this species group is distinguished by the presence of a
segminiplanate P1 element with a high, fused carina, and an alate S0 element
with anterior processes that bifurcate at the cusp. This S0 element
morphology is unlike those of other species from the upper Anisian of North
America, but similar to those from the Lower Triassic. The new reconstruction
demonstrates that Neogondolella ex gr. regalis does not
belong to the genus Neogondolella, nor to any other Triassic
gondolellid genus. It is therefore proposed that Neogondolella ex
gr. regalis should be referred to a new genus.
加拿大不列颠哥伦比亚省安尼西亚(中三叠世)Neogondolella ex gr. regalis Mosher, 1970 (Conodonta)多元素仪器的重建
摘要以加拿大不列颠哥伦比亚省上阿尼西统的资料为基础，重建了中三叠统牙状齿neogondolella ex r. regalis的多元素仪器。这个物种群的器官的特点是具有高的融合隆突的半平面P1元件和具有在尖端分叉的前突的形位50元件的存在。这种S0元素的形态与北美上三叠统的其他物种不同，但与下三叠统的物种相似。新的重建表明，Neogondolella ex gr. regalis不属于Neogondolella属，也不属于任何其他三叠纪gondolellid属。因此，我们认为新贡多拉菌是一种很好的细菌。帝王蝶属应归入一个新属。
