We report 18 conodonts specimens embedded in 4coprolites from the Nanlinghu Formation(Olenekian,Early Triassic)at the Pingdingshan-Majiashan Section in Chaohu,Anhui Province.This is the first report of conodonts as prey animals in the Triassic Period.The coprolite specimens are grey to black in color,and they have weel-defined boundaries and can be distinguished from the dark-brownish host argillaceous limestone which is rich in organic matter.The coprolites are oval or elongate in shape,and they are slightly compressed due to compaction.These coprolites may have been produced by arthropods whose body fossils are also found in the same deds.Some conodont elements can be identified as Neospathodus homeri and Neospathodus sp.,which are important components of the N.homeri or N.anhuiensis Zone.The conodonts from the coprolites suggest that the fossiliferous beds belong to the Spathian Substage of the Olenekian Stage(Early Triassic),consistent with biostratigraphic data from previous studies.
