JOSE BONAPARTE: MASTER OF THE MESOZOIC 

One of the most delightful palaeontologists to grace our Earth was José Fernando Bonaparte (14 June 1928 – 18 February 2020). We often think of those who have shaped our past and found many of the firsts of their region as living in ancient history, but José left us just this past year in February. He was a prolific and hard-working Argentinian palaeontologist who you'll know as

Probelesodon minor Fossil 

  This fossil reptile skull and jaw were displayed on August 2022, at the Harvard Museum of Natural History in Cambridge, Massachusetts, USA. It is called Probelesodon minor (Romer, 1973).

Titanosaurian (Skull) Fashion Week 

Hasta hace bien poco, en las introducciones de cualquier artículo descriptivo sobre material craneal de saurópodos titanosaurios una de las primeras frases que se podían leer era (a grandes rasgos y con sus variaciones): “Los titanosaurios fueron los saurópodos con más éxito del Cretácico. Sin embargo, se conocen gracias a sus restos postcraneales y dientes, ya que los craneales son pocos y

Viavenator: hay un nuevo cazador en el camino 

De las manos de Ceratosaurus pasamos a hablar de un nuevo ceratosaurio, concretamente un abelisaurido de edad Satoniense (Cretácico Superior) de Argentina, Viavenator exxoni. Los abelisauridos son un grupo de terópodos de tamaño medio a grande que ocuparon Suramérica y el sur de Europa durante el periodo Cretácico.

Notocolossus is a beast 

This will be all too short, but I can’t let the publication of a new giant sauropod pass unremarked. Yesterday Bernardo González Riga and colleagues published a nice, detailed paper describing Notocolossus gonzalezparejasi, “Dr. Jorge González Parejas’s southern giant”, a new titanosaur from the Late Cretaceous of Mendoza Province, Argentina (González Riga et al. 2016). The paper

The Southern Cone of South America 

I am sorry I was not able to post pictures from my recent South America trip with Smithsonian Journey's. I experienced some computer problems and/or was in places with limited or no internet service (yes, places like that still exist). But here are a few now with more to follow.This was taken from my room at the Las Yamanas Hotel on the shores of the Beagle Channel. The photo was taken in Ushuaia, Argentina but across the channel is Chile. The channel, named after the ship Charles Darwin sailed [...]

Um (titanossáurio) gigante e sem medo! 

Já não é propriamente novidade, Dreadnoughtus schrani foi um dos titanosáurios descobertos ao largo do ano de 2014. Este estudo foi liderado por Kenneth J. Lacovara, no qual se sumaram mais 16 autores, e teve como objectivo a breve descrição num dos maiores saurópodes encontrados no Cretácico. Esta descoberta vem assim aumentar a diversidade (que já não é pequena) de saurópodes
