Abstract

Eight new species of the conodont Neogondolella are 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 of N. cuneiforme, N. curva, N. hastata, N. dilacerata, N. indicta, N. panlaurentia, N. tenera, and N. vellicata n. spp. Several of these species are widespread, as specimens of N. curva, N. hastata, N. indicta, N. panlaurentia, N. tenera, and N. vellicata are found in contemporary collections from Nevada, whereas N. panlaurentia has also been recovered from the Canadian Arctic. This distribution promises to significantly improve correlation among Anisian sections in North America.
