Lorosuchus is an extinct genus of sebecid mesoeucrocodylian known from the Río Loro Formation in Tucumán Province of northwestern Argentina.
The Riochican (Spanish: Riochiquense) age is a period of geologic time within the early Eocene epoch of the Paleogene, used more specifically within the South American land mammal ages (SALMA) system. This age is named after the Río Chico Group of...
Bretesuchus is an extinct genus of sebecosuchian mesoeucrocodylian within the family Sebecidae known from northwestern Argentina. It was a large apex predator (total length approximately 4 m).
The Itaboraian (Portuguese: Itaboraiense) age is a period within the Early Eocene geologic time (53.0–50.0 Ma) epoch of the Paleogene, used more specifically with South American land mammal ages (SALMA). It follows the Riochican and precedes the...
Amilnedwardsia is a genus of extinct ungulates in the family Macraucheniidae. The type species is Amilnedwardsia brevicula which lived between 47.8 and 38.0 million years ago in modern-day Argentina.
Sebecidae is an extinct family of prehistoric terrestrial sebecosuchian crocodylomorphs, known from the Late Cretaceous and Cenozoic of Europe, South America and the Caribbean. They were the latest surviving group of non-crocodilian crocodylomorphs....
The South American land mammal ages (SALMA) establish a geologic timescale for prehistoric South American fauna beginning 64.5 Ma during the Paleocene and continuing through to the Late Pleistocene (0.011 Ma). These periods are referred to as ages,...
The year 2011 in archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is...
