Coping between crises: Early Triassic-early Jurassic bivalve diversity dynamics
(Elsevier Science, 2011-11)
The Triassic is bounded by two of the most severe biotic crises, but nevertheless this time was, for bivalves, both a recovery and a diversification period, and a moment to fully exploit some of their evolutionary novelties. ...
First Late Triassic Record of a Paleoentomofauna from South America (Malargüe Basin, Mendoza Province, Argentina)
(Wiley Blackwell Publishing, Inc, 2010-08)
Late Middle Triassic to early Late Triassic insects from Argentina have been previously described from the Bermejo and Cuyana Basins where they have been recovered from the Ischichuca‐Los Rastros and Potrerillos‐Cacheuta ...
The Late Triassic record of cynodonts: Time of innovations in the mammalian lineage
(Springer, 2018)
The Triassic period witnessed a great diversification of lineages, recovering from one of the worst extinction events known in Earth’s history. Therapsids, the lineage that includes mammals as the only living members, ...
Phylogenetic reassessment of Pisanosaurus mertii Casamiquela, 1967, a basal dinosauriform from the Late Triassic of Argentina
(Cambridge University Press, 2017-08-04)
Pisanosaurus mertii was originally described on the basis of an incomplete skeleton from the early Late Triassic (Carnian)of northern Argentina. It is consistently regarded by most authors as a very basal ornithischian, ...
Bird-like fossil footprints from the Late Triassic
(Nature Publishing Group, 2002-06)
The study of fossilized footprints and tracks of dinosaurs and other vertebrates has provided insight into the origin, evolution and extinction of several major groups and their behaviour; it has also been an important ...
A new temnospondyl record from the Upper Triassic of Argentina
(Asociación Paleontológica Argentina, 2005-12)
The Brachyopoidea is a group of Mesozoic temnospondyls with flat, parabolic skulls that were recently reviewed and considered to include Brachyopoidea and Chigutisauridae (Warren and Marsicano, 2000; Yates and Warren, 2000, ...
Systematic revision of Late Triassic marine gastropods from Central Perú: considerations on the Late Triassic/Early Jurassic faunal turnoverRevisión sistemática de los gastrópodos marinos del Triásico superior de Perú Central: consideraciones sobre el recambio faunístico en límite Triásico tardío/Jurásico temprano
(Servicio Nacional Geologia y Minería, 2015-01)
The Late Triassic/Early Jurassic boundary is marked by a mass extinction event which had an important effect on the marine benthic communities on a global scale. In the Andean region of South America, however, the impact ...

(Taylor & Francis, 2016-08)
The salle Grylloblattidae or Grylloblattodea order

and have relictual distributions) is one of the least diverse extant insect groups (with 29 species and five ...
