New species of the conodontNeogondolellafrom the Anisian (Middle Triassic) of northeastern British Columbia, Canada, and their importance for regional correlation
AbstractEight new species of the conodontNeogondolellaare described from the Anisian (Middle Triassic) of northeastern British Columbia. The subtlety of morphological variation in this conodont genus has hampered biostratigraphical correlation, but large, often independently dated collections have enabled the description ofN.cuneiforme,N.curva,N.hastata,N.dilacerata,N.indicta,N.panlaurentia,N.tenera, andN.vellicatan. spp. Several of these species are widespread, as specimens ofN.curva,N.hastata,N.indicta,N.panlaurentia,N.tenera, andN.vellicataare found in contemporary collections from Nevada, whereasN.panlaurentiahas also been recovered from the Canadian Arctic. This distribution promises to significantly improve correlation among Anisian sections in North America.
