The new genus and types of the Abelisaurids Theopod were discovered by a team of paleontologists from Argentina, Brazil and Great Britain.

Recently open species of dinosaurs, Vitosaura ColozacaniOur planet wandered about 80 million years ago (late chalk era).
The ancient creature belongs to Abelisauridae, a group of predatory dinosaurs, which flourished mainly in Gondwan in the Cretaceous period.
The petrify recording of this group is currently presented by more than 25 species, and their most complete and abundant notes are taken from Argentinean Patagonia.
“Abelisauridae is the treasure of the ceratosavrov Teropod, built in 1985 and is characterized by the presence of a reliable, short and high skull, well-equipped maxill and frontals, highly pneumatic axial skeletons and reduced front maximum moments,” said Dr. Garold Dzhimena from the coniferous and his colleagues.
“The discovery of multiple types of Abelizaurides over the past few decades, mainly in the Gondwanan spouses, has significantly improved our understanding of this group Teropod.”
“Abelisauridae was the dominant treasury of Teropod dinosaurs during Cretaceous in Gondwan, with numerous records in North Africa and Indo-Madagascar, and they also reached Loracia in the fact that it is central Europe at present.”
“In addition to these records, the group was surprisingly successful in South America with a very abundant fossil record.”
Froken bones Vitosaura Colozacani were excavated during excursions in 2009 and 2010 in the Tama area Los Llanos Formation In the province of La Rioch, north -west Argentina.
“The remnants of Teropod are represented by the first dorsal center, the second dorsal vertebra, partial sacrum, left ileum, pubic and Ishim and other uncertain elements,” the paleontologists said.
“Samples were associated with several post -jerks of the Titanosaurus.”
Vitosaura Colozacani He was an abolisaurus of medium size with a total length between 4.5-5.5 m (15-18 feet).
The species lived in a seasonal, semi -dodgy and drained environment, and the average annual amount of precipitation ranged from 230 to 450 mm per year.
“Opening Vitosaura Colozacani In the campanian layers of the formation of Los -Lalanos in the province of La -Riokha, the geographical distribution of Abelizaurides expands, but the consequences of new species are limited by its incompleteness and stream states that we note in many, recent phylogenetic tests oriented towards the abelizaurides interruptions. ”
“We believe that it is necessary to conduct new research to improve the topological reliability of the phylisauridae phylogenesis and detect a new material prescribed for Vitosaura Colozacani To more reliably check the phylogenetic hypotheses discussed in our study. ”
