A new sawshark, Pristiophorus laevis , from the Eocene of Antarctica with comments on Pristiophorus lanceolatus
(Taylor and Francis Ltd., 2016-11)
The highly fossiliferous Eocene deposits of the Antarctic Peninsula are among the most productive sites for fossil remains in the Southern Hemisphere and offer rare insights into high-latitude faunas during the Palaeogene. ...
Dinosaur remains from the La Quinta Formation (Lower or Middle Jurassic) of the Venezuelan Andes
(Springer Heidelberg, 2008-06)
Dinosaur remains are exceptionally scarce in northern South America and Jurassic faunas from this area are particularly poorly known. We provide descriptions of new dinosaur specimens from a bonebed in the La Quinta Formation ...
Dental anomalies in Dromiciops gliroides (Microbiotheria, Microbiotheriidae), Caenolestes fuliginosus and Rhyncholestes raphanurus (Paucituberculata, Caenolestidae)Anomalías en la dentición de Dromiciops gliroides (Microbiotheria, Microbiotheriidae), Caenolestes fuliginosus and Rhyncholestes raphanurus (Paucituberculata, Caenolestidae)
(Sociedad de Biología de Chile, 2007-12)
Dental anomalies are described after analyzing series of skulls and mandibles of three species of South American marsupials: the monito del monte (Dromiciops gliroides), the silky shrew-opossum (Caenolestes fuliginosus) ...

(Society of Vertebrate Paleontology, 2017-11)
Seymour Island, Antarctic Peninsula, is known for its wealth of fossil remains. This island provides one of the richest fossiliferous Paleogene sequences in the world. Chondrichthyans seemingly dominate this Eocene marine ...
Systematic revision of a Miocene sperm whale from Patagonia, Argentina, and the phylogenetic signal of tympano-periotic bones in Physeteroidea
(Polish Academy of Sciences. Institute of Paleobiology, 2021-01)
Sperm whales (Physeteroidea) include today only two genera of morphologically disparate odontocetes: the largest toothed whale known (Physeter macrocephalus) and small sized forms (Kogia spp.). In contrast, their fossil ...

(Society of Vertebrate Paleontology, 2010-11)
Cavioidea sensu stricto groups three traditionally recognized families that are characterized by hypsodont, double-heart-shaped cheek teeth and moderate hystricognathy: Eocardiidae, Caviidae, and Hydrochoeridae. Eocardiidae ...
New cladotherian mammal from southern Chile and the evolution of mesungulatid meridiolestidans at the dusk of the Mesozoic era
(Nature Publishing Group, 2021-12)
In the last decades, several discoveries have uncovered the complexity of mammalian evolution during the Mesozoic Era, including important Gondwanan lineages: the australosphenidans, gondwanatherians, and meridiolestidans ...
