Diuqin lechiguanae Porfiri et al., 2024 (new genus and species)

(Digital models of the vertebrae and humerus [upper arm bone] of Diuqin lechiguanae, from Porfiri et al., 2024)

Meaning of name: Diuqin = bird of prey [in Mapudungun]; lechiguanae = for Lechiguana [witch character in the 1975 film Nazareno Cruz y el Lobo]

Age: Late Cretaceous (Santonian)

Where found: Bajo de la Carpa Formation, Neuquén, Argentina

How much is known: Partial skeleton of one individual, including several vertebrae and the left humerus (upper arm bone).

Notes: Diuqin was probably an unenlagiine, a group of paravian theropods typically considered members of the Dromaeosauridae. Unenlagiines had long snouts and numerous unserrated teeth, which has led to the suggestion that they were primarily piscivorous (fish-eating). The humerus of Diuqin bears some resemblance to that of the younger and much larger Austroraptor, the biggest unenlagiine known.

The type specimen of Diuqin also preserves some bite marks on its humerus, suggesting that its carcass had been fed on, possibly by a crocodyliform, mammal, or another theropod dinosaur (maybe even another Diuqin).

G-Gigantosaurus

1. Taxonomic Group: Giganotosaurus is a genus within the theropod clade, specifically classified under the family Carcharodontosauridae, known for their large size and predatory nature.

2. Size and Weight: Giganotosaurus was one of the largest theropods, measuring approximately 12-13 meters (39-43 feet) in length and weighing around 8-14 tons.

3. Time Period: This dinosaur lived during the Late Cretaceous period, approximately 98 to 97 million years ago.

4. Location: Fossils of Giganotosaurus have been found in South America, particularly in the Patagonia region of Argentina.

5. Diet: As a carnivore, Giganotosaurus preyed on large herbivorous dinosaurs, utilizing its powerful jaws and serrated teeth to take down and consume its prey.

6. Distinctive Features: Giganotosaurus had a massive skull with a wide, robust body. Its forelimbs were relatively short, with three-fingered hands, each finger ending in a sharp claw.

7. Head Structure: The skull of Giganotosaurus was large and elongated, with a set of sharp, serrated teeth ideal for slicing through flesh. It had strong jaw muscles for a powerful bite.

8. Movement and Behavior: Giganotosaurus was a bipedal predator, relying on its strong hind limbs for locomotion. It was likely capable of fast, sustained runs to chase down prey.

9. Initial Discovery: The first fossils of Giganotosaurus were discovered by Rubén D. Carolini in 1993 in the Neuquén Province of Argentina. The genus name was described by Rodolfo Coria and Leonardo Salgado in 1995.

10. Cultural Significance: Giganotosaurus is often highlighted in media and documentaries as one of the largest predatory dinosaurs, contributing valuable insights into the diversity and adaptations of large theropods.

11. Skin and Fossil Finds: While no skin impressions have been found, numerous skeletal fossils, including parts of the skull, vertebrae, and limbs, have been discovered, providing a detailed understanding of its anatomy.

An article published in the journal "Acta Palaeontologica Polonica" reports the identification of a species of titanosaur that lived about 95 million years ago, in the Cretaceous period, in today's Argentina and was named Bustingorrytitan shiva. María Edith Simón and Leonardo Salgado examined the partial skeletons of four specimens discovered in the village of Villa El Chocón, in the Neuquén province of Patagonia. This area of Argentina was home to various species of titanosaurs, the largest animals to have lived on land.

1998 - foundation of Coordinadora Arauco-Malleco

2009 - formation of Resistencia Ancestral Mapuch

2010-2011 - hunger strikes

The colonization of Argentina and Chile began between 1535 and 1540, after which they became part of the Spanish Empire. In the long Arauco War, the Mapuche people fought against the Spaniards for their freedom and lands. They eventually won and reversed Spanish colonization of Araucanía.

After Chile achieved independence in 1844, the peace between the Mapuche and the new government evaporated, since the latter did not recognize the Mapuche as independent. Eventually, the government did so through the Indigenous Settlement Commission and the Treaty of Tapihue, but the Chilean population continued to acquire Mapuche lands.

The passing of the Indigenous Reservations Law led to mass rebellion by the Mapuche people in 1870 and 1880. Subsequently, the Chilean government started the “pacification” of Araucanía, which was essentially an occupation of the region. Salvador Allende’s government restored some Mapuche land, but the situation was reversed under Pinochet’s dictatorship.

When democracy was restored, the Chilean government passed the Indigenous Peoples Act to recognize Mapuche participation and land, cultural, and development rights, but most Mapuches feel disappointed. Since then, numerous incidents have happened in Araucanía, including hunger strikes and attacks against both sides.

Mapuche people

There are around 1,950,000 Mapuches, of which 90% live in Chile. They speak Mapuche, an Araucanian language, and Spanish.

Mapuche people mostly practice Christianity, but also retain some of their traditional beliefs. Their economy is based on agriculture, and they are organized under extended families.

5th of November 2024: Liolaemus tromen

Let us take a moment to take a look at Liolaemus tromen before you go about the rest of your day. They’re a type of lizard initially described in 2012 from Argentina [1].

They are 6-8 cm long, which sets them apart from their closest relatives, who all tend to be shorter than that [1]. As there are over 200 species in the Liolaemus genus, it was a bit under debate as to which sub-genus group they belong to. While the initial paper inferred several possibilities based on their size and body structure, since it’s been genetically confirmed that they are part of the L. rothi group [2].

Males and females can be easily told apart by their stomach colouration, as males have a predominantly dark stomach while females have a lighter one. There’s not been too much study on their lives, it is likely that they predominantly eat insects. In the field they were mostly found near the larger bushes in their habitat [1].

They were named after the Tromen Volcano in the Neuquén Province in Argentina, which is where they were originally found [1]. While their total range does no appear to be very large, they have been found in surveys there for many years, and so they are unlikely to be in decline. The IUCN ranked them under Least Concern, though this assessment is a decade old at this point [3].

FIRST RECORD OF AN ABELISAURID (DINOSAURIA, THEROPODA) NATURAL ENDOCAST, AND COMMENTS ON SKULL ROOF ORNAMENTATION

Published 18th November 2023

The second natural endocast described for a dinosaur in Argentina and the first for a theropod, as well as 2 associated skull roofs, is assigned to an Abelisaurid from the Bajo de la Carpa Formation in Neuquén Province, Northern Patagonia. The relative size of the cranial specimens is interpreted as similar to that of Llukalkan, however the marked reduction of ornamentation in the associated skull roofs indicates a distinctive pattern that differentiates them from Llukalkan and Viavenator. It is possible the described cranial elements represent a new species of small bodied albelisaurid, potential sexual dimorphism or a juvenile individual of a known species; it is unknown what these remains represent currently.
