“…The upper section of the Loreto Formation exposed at Río de Las Minas near Punta Arenas includes so far at least 13 different taxa from a single level of Priabonian age (Otero et al, 2012). The second and richest locality is Sierra Baguales in the northern part of the Magallanes Region, which has provided remains of five typically Maastrichtian taxa and at least eighteen Paleogene taxa (Otero et al, 2013a).…”

ABSTRACT. Here we studied new fossil chondrichthyans from two localities, Río de Las Minas, and Sierra Dorotea, both in the Magallanes Region, southernmost Chile. In Río de Las Minas, the upper section of the Priabonian Loreto Formation have yielded material referable to the taxa Megascyliorhinus sp., Pristiophorus sp., Rhinoptera sp., and Callorhinchus sp. In Sierra Dorotea, middle-to-late Eocene levels of the Río Turbio Formation have provided teeth referable to the taxa Striatolamia macrota (Agassiz), Palaeohypotodus rutoti (Winkler), Squalus aff. weltoni Long, Carcharias sp., Paraorthacodus sp., Rhinoptera sp., and indeterminate Myliobatids. These new records show the presence of common chondrichtyan diversity along most of the Magallanes Basin. The new record of Paraorthacodus sp. and P. rutoti, support the extension of their respective biochrons in the Magallanes Basin and likely in the southeastern Pacific.

Here, we review and discuss the records and taxonomy of the Ypresian (Eocene) chondrichthyans from the famous Bolca Konservat-Lagerstätte in northeastern Italy. Despite the outstanding diversity and the numerous studies focusing on the actinopterygian faunas from Pesciara and Monte Postale, the current knowledge about the systematics, taxonomy and phylogenetic relationships of the cartilaginous fishes from these Eocene sites remains elusive and largely inadequate. The celebrated Eocene Bolca Lagerstätte has yielded several exquisitely preserved articulated remains of chondrichthyan fishes in which delicate structures and soft tissues are preserved, as well as isolated teeth. The cartilaginous fish assemblage of Bolca comprises at least 17 species-level taxa belonging to 10 families in 6 orders, including selachians (Carcharhiniformes, Lamniformes), batoids (Torpediniformes, Myliobatiformes, Rajiformes) and holocephalans (Chimaeriformes). The occurrence of holocephalans represented by an isolated fin-spine of the chimeroid Ischyodus in the Bolca assemblage is reported here for the first time and represents the first record of chimeroids in the Eocene of Italy and also southern Europe. The Bolca chondrichthyan assemblage is remarkably different from those of other contemporaneous Boreal or Tethyan deposits, suggesting that its taxonomic composition is largely influenced by the palaeoenvironmental context. However, this synoptic review also highlights the importance of detailed revisions of all chondrichthyan remains from the Bolca Konservat-Lagerstätten.
