| 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. |
| Summary | (Plain Language Summary, not published)
The conodont microfossil Neogondolella regalis is an unusual species for its genus. This paper reconstructs the complete feeding apparatus of this
organism based on specimens collected from hydrocarbon core from the subsurface of British Columbia, Canada. This new reconstruction of the complete apparatus demonstrates that this species is different from others belonging to the genus
Neogondolella, and suggests that a new genus should be created to contain regalis. This has implications for dating and correlating rocks of the Canadian Cordillera, where this species is very common. |
