| dc.abstract.en | Bicuspid, tricuspid and tetracuspid postcanine teeth of a new non-mammaliaform eucynodont, Polonodon woznikiensis gen. et sp. nov. from the mid-late Carnian (early Late Triassic) of Woźniki clay-pit, Silesia (southern Poland) show incipient root division. They are similar to teeth of Dromatheriidae from the Carnian (early Late Triassic) to the Rhaetian (late Late Triassic) of Europe, India, and USA and the dentition of brasilodontids from the early Norian (mid Late Triassic) of Brazil. The P. woznikiensis teeth differ from those of the latter group mostly in the absence of cingulum. Some of the new fossils from Silesia provide the oldest Laurasian record of eucynodont teeth with the main cusp (a) anterior edge very long as the mesial cusp b is placed much lower than cusp c (distal). The contemporaneous Alemoatherium huebneri, from Gondwana, had similar postcanines. The findings from Poland indicate that this postcanine morphology was present in non-mammaliaform cynodonts from both hemispheres as early as the mid-late Carnian. The distal end of the humerus from the same locality is also described. |
