a tooth-like fossil, amber in colour. Conodonts occur in sediments from the CAMBRIAN to the TRIASSIC and are thought to be associated with the mouth-parts of primitive chordates such as members of the AGNATHA.

Records of the conodont Icriodus woschmidti allowed these beds to be dated more precisely as the Lochkovian (Early Devonian) (Zhivkovich & Chekhovich 1985).
However, recent faunal studies, especially on conodonts, suggest the extinction event transcends the formational boundaries, and place the Permian-Triassic boundary within the basal or middle part of the Kathwai Member of the Mianwali Formation (see Pakistani-Japanese Research Group,1985; Wardlawand Mei, 1999).
Two assemblage zones and one acrozone for Permian deposits and two assemblage zones for Triassic deposits were identified based on the emergence, decline and expanding stratigraphic accumulation index for conodonts having known elements.
This seminal study will revolutionise both our understanding of the conodont fossil record the role of intrinsic innovation versus extrinsic forces of competition and environmental change, it will also establish an entirely new suite of investigative tools to the discipline.
