Reconstruction of the multielement apparatus of Neogondolella ex gr. regalis Mosher, 1970 (Conodonta) from the Anisian (Middle Triassic) in British Columbia, Canada

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.
