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).
In other words, the observed Ce anomaly is not limited to marine carbonate, conodonts and ichthyoliths, while the whole-rock Ce anomaly can be used as an indicator of intensity of anoxia and therefore of eustatic sea-level.
Several marine fossils not found in underlying formations suddenly appear here, including those of gastropods; crinoids; rare corals; small conodonts (eel-like creatures); and armored, plate-mouthed fish known as placoderms.
The age of the Buchans Group is based on Whiterockian conodonts recovered from carbonate clasts (Nowlan and Thurlow 1984, 1987) and U-Pb zircon ages (462 [+ or -] 3 and 465 [+ or -] 3 Ma) from the upper part of the unit (Zagorevski et al.
Until 1973, geologists assumed that the Stari Trg Series sedimentary sequence was Silurian-Ordovician, but in that year Yugoslavian geologists found fossils (conodonts) in the sequence which suggest that some of the limestones could be of Triassic age (Topalovic, personal communication, 1973).
