Dinosaurs likely originated in the Middle Triassic, but the earliest unambiguous dinosaur specimens are from the middle-late Carnian age, primarily in the Southern Hemisphere, with potential eviden…| Letters from Gondwana.
Following on the unexpected success of a scientific livestream that drew 61,000 viewers—tripling the audience of The Voice Argentina—a team of paleontologists is preparing for a new groundbreaking broadcast. On August 4th, the public was captivated by a live journey to the depths of the South Atlantic; this October, they will be transported 70 million […]| Letters from Gondwana.
The Cretaceous beds of Patagonia contain the most comprehensive record of non-avian theropods from the Southern Hemisphere. This includes Megaraptora, a clade of medium-sized, highly pneumatized th…| Letters from Gondwana.

Pachycephalosaurians, with their distinctive domed heads, are an enigmatic group of small ornithischian dinosaurs. Most pachycephalosaurid remains are known from the Late Cretaceous of North Americ…| Letters from Gondwana.
Dromaeosauridae is a clade of highly specialised small- to mid-sized theropod dinosaurs closely related to birds. Their fossils have been found in North America, Europe, Africa, Asia, South America…| Letters from Gondwana.
During the paleobiological revolution of the 1970s and 1980s, the status of paleontology as an evolutionary discipline was attempted to be established by a number of paleontologists. From 16th to 19th October 1980, the Field Museum of Natural History held the Macroevolution Conference, a historic event that challenged the four-decade-long dominance of the Modern Synthesis.

Eutyrannosauria, the superfamily of carnivorous dinosaurs that includes the iconic Tyrannosaurus rex, dominated the Asian and North American terrestrial faunas during the latest Cretaceous. Through…| Letters from Gondwana.
The Triassic beds of Argentina and Brazil play a key role in understanding of the origin and early diversification of Dinosauria. The first recorded dinosaurs include some predatory forms, such as …| Letters from Gondwana.
Therizinosauria is a group of unusual theropod dinosaurs known from Cretaceous deposits in Asia and North America. The clade exhibits unique features, including lanceolate teeth, a rostral rhamphotheca, and a broad, opisthopubic pelvis. Some of those characteristics are associated with a shift in dietary preferences and an adaptation to herbivory. But the most striking feature, […]| Letters from Gondwana.
The evolution of the avian skull is marked by radical transformations of the braincase, palate, and snout. Brain size correlated with major evolutionary innovations like cognition, flight, environm…| Letters from Gondwana.
