The taxonomy, diversity, evolutionary lineages, and stratigraphical
distributions of Middle and early Late Triassic conodonts are reviewed and
re-evaluated. Twenty-five genera are recognized in the Middle and early
Late Triassic, including a new genus cited in open nomenclature. Of these,
24 genera are assigned to two families and seven subfamilies. The family
Gondolellidae consists of the subfamilies Cornudininae, Epigondolellinae,
Neogondolellinae, Novispathodinae, Paragondolellinae and
Pseudofurnishiinae. The family Gladigondolellidae is monotypic, consisting
of the subfamily Gladigondolellinae. The genus Neostrachanognathus is not
assigned to any family or subfamily as its origin is unclear. Conodont
provincialism was low in the early Anisian, but from the late Anisian
faunistic differences started to increase and became stronger during the
early Ladinian, reaching a peak around the mid-Ladinian. Provincialism
remained strong until the earliest Carnian and changed to an all-Triassic
low in the early Tuvalian. The provincialism between North America and
Tethys rebounded on the specific level during the late Tuvalian.
Diversities on generic and specific levels have been established, and two
major conodont diversity cycles are recognized: the first ranges from the
Bithynian (early Anisian) to the Julian (late early Carnian), and the
second is restricted to the Tuvalian (late Carnian).
LIST OF CONODONT HOLOTYPES RE-ILLUSTRATEDThis file provides the references
of the conodont images re-illustrated in the paper. All conodont images
are holotypes, exceptions are mentioned.STATISTIC ANALYSES OF EARLY,
MIDDLE AND EARLY LATE TRIASSIC (CARNIAN) PUBLICATIONSThis file provides
the analyses of Early, Middle and early Late Triassic (carnian)
publications and number of conodont species. It also provides important
information about the conodont publications which is favorable for
conodont worker to find the relevant literatures.
