Rhynchocephalians: The least known South American LepidosaursRhyncocéfalos: Los lepidosaurios sudamericanos menos conocidos
(Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" e Instituto Nacional de Investigación de las Ciencias Naturales, 2016-05)
The history of Rhynchocephalia in South America is rich and complex. Although the Triassic forms were related to the global lineages, including clevosaurs and derived herbivorous forms, along Jurassic new lineages succeeded. ...
The youngest South American rhynchocephalian, a survivor of the K/Pg extinction
(The Royal Society, 2014-08)
Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara (Sphenodon) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern ...
The diversity of Triassic South American sphenodontians: a new basal form, clevosaurs, and a revision of rhynchocephalian phylogeny
(Taylor & Francis, 2021-11)
Rhynchocephalians are a group of lizard-like diapsid reptiles that were very diverse during the Mesozoic but are now restricted to a single extant genus in New Zealand. Recent cladistic analyses have revealed two major ...
Bridging the gap: Sphenodont remains from the Turonian (Upper Cretaceous) of Patagonia. Palaeobiological inferences
(Academic Press Ltd - Elsevier Science Ltd, 2019-06)
Rhynchocephalians are a lepidosaur clade with a single living species. Here we report the first record of an eilenodontine sphenodontian from Turonian beds in South America. The new Turonian basal eilenodontine sphenodontian, ...
Earliest Tuatara relative (Lepidosauria: Sphenodontinae) from Southern ContinentsEl más temprano pariente del Tuatara (Lepidosauria: Sphenodontinae) de los continentes australes
(Asociación Paleontológica Argentina, 2021-09)
The New Zealand tuatara (Sphenodon) is the sole surviving rhynchocephalian of a once thriving group across Pangea during early Mesozoic times. Outside New Zealand, close relatives of the tuatara (sphenodontines) are known ...
A new sphenodontian (Lepidosauria: Rhynchocephalia) from the Late Triassic of Argentina and the early origin of the herbivore opisthodontians
(The Royal Society, 2013-10)
Sphenodontians were a successful group of rhynchocephalian reptiles that dominated the fossil record of Lepidosauria during the Triassic and Jurassic. Although evidence of extinction is seen at the end of the Laurasian ...
