“…Recently, Pfeil (1984) and Keyes (1984) described teeth of Megascyliorhinus from the Tertiary of New Zealand (in the phosphorite-bearing glauconitic sand ofthe Central Chatham Rise). Pfeil identified the specimens as Megascyliorhinus sp.…”

A new species of Megascyliorhinus (M. trelewensis) comes from the Monte Le6n Formation ("Patagoniano" partim; upper Oligocene-lower Miocene) of eastern Patagonia. It is compared with other species of Megascyliorhinus, in particular M . miocenicus, although there is no implication of relationship to the latter. An Eocene-Pleistocene size increase in the species of Megascyliorhinus appears to be demonstrated. The supposed relationships with Megachasma pelagios are discussed. RESUMEN -Una nueva especie de Megascyliorhinus (M . trelewensis) proviene de la Forrnaci6n Monte Le6n ("Patagoniano" partim; Oligoceno superior-Mioceno inferior) de Patagonia oriental, Argentina.Se com para con otras especies del genero, Se asemejaria global mente a M . miocenicus, aunque no implica relacionarlos. Un incremento del tamaiio de las formas eocenas a las oligoceno-pleistocenas es seiialado. Se discuten las supuestas relaciones con Megachasma pelagios.

“…The Northern and Pacific records of Megascyliorhinus have been hypothesized by Cappetta and Ward (1977), Pfeil (1984), and Keyes (1984) as representing fishes that inhabited relatively deep waters. M. trelewensis inhabited a warm temperate sea (see Cione, 1978).…”

“…The current find in Priabonian levels of the Loreto Formation proves the occurrence of this taxon in younger beds along the Magallanes Basin. Regionally, the genus (represented by a probable different species with higher crowns) was recovered from Oligocene beds of New Zealand (Keyes, 1984) proving its widespread distribution during the Eocene-Oligocene boundary along the WBP (Zinsmeister, 1979 (Kriwet, 2005;Reguero et al, 2013;Otero et al, 2012Otero et al, , 2013a Kriwet and Gaździcki (2003). Description: Mandibular tooth plate with a single central hypermineralized pad restricted to the distal part of the coronal surface, flanked by narrow tritors on the symphyseal and/or labial edges (Otero et al, 2013b).…”

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.
