Collected by B. Kröger, M. Isakar in 2006

Collection methods: surface (float)

• " [...] from our own collections (B.K. and M.I.) in summer 2006. A single 4 m × 4 m large block at the cliff about 2 km northwest of Paldiski at the Pakri Peninsula, Estonia yielded about 50 specimens of small nautiloids on a bed surface ca. 0.02 m above the base of the Aseri Limestone, comprising small discosorids, oncocerids, tarphycerids and orthocerids. The material is in the Paleontological collection of the University of Tartu, Museum of Geology, Tartu, Estonia (TUG)."
