The identify Ibira comes from the mixture of the phrases of the town the place it was found.ania “, which in Greek means “pilgrim” and “moron”the Latin phrase is small.
This discovery was obtained consequently of work carried out because the 90s and revealed final Thursday (15) in a global scientific journal.
In an interview with g1, Bruno Navarro, a paleontologist on the Museum of Zoology of the University of São Paulo (USP) and the primary precursor of the invention, gave detailed details about the work carried out by the researchers.
“Collections started in 1999, the identical 12 months they found some fossils of a brand new species. But the fabric of the holotype – the person from which the identify of the species was given – Professor Dr. Marcelo Adorna Fernandez, in 2005,” mentioned Bruno.
Viriato Antonio Lobo de Araujo was Ibira’s secretary of tourism and one of the volunteers for the excavation. He was accountable for discovering the fabric in Vila Ventura, the place the work was executed.

“Marcelo defined to us how he did it. I solely noticed one fillet whereas digging. I began digging and found the fossil,” defined the secretary.
The materials found by Marcelo and Viriato was analyzed for Bruno in 2015. It was this 12 months that he observed some traits of the fossil and realized that it is perhaps a brand new species.
“When we accumulate any fossil, we examine it with comparable objects. If we discover one thing else, we’ll look deeper if it is perhaps associated. But all that is for evaluation,” mentioned Bruno.

From the work, Bruno and the researchers realized that the brand new species had some anatomical traits that set it aside from others.
One of them is buildings Hebrew parva recommended hyperpneumatization of their axial skeleton, which means hole areas in the vertebrae even harbor remnants of air sacs used for temperature management. This kind of construction resembles birds and differs from different dinosaurs.

In addition to proving that the species was smaller than different titanosaurs, what shocked the group was that the “dwarf” kind was the first recorded in the Americas.
“Dwarf titanosaurs have been recorded in some elements of Europe since 1915. But the continent was an archipelago, so the confinement between them compelled these animals to be small as a result of drawback of territory and assets. So we have been questioning: what’s a dwarf animal doing in Brazil,” mentioned Bruno.
Because the Ibira area had no connection to the ocean, researchers have been keen to grasp how the surroundings on the time affected the dimensions of the species.

According to Bruno, one of the first causes is that the species prefers a low-fat weight loss plan, corresponding to shrubs.
Moreover, throughout the Cretaceous interval, when Hebrew parva lived in, the northwestern area of São Paulo was characterised by a really dry local weather and dry and lengthy seasons. It was this hostile surroundings that chosen the small herbivorous dinosaurs.
“Smaller animals would have better endurance as a result of they required fewer assets and have been capable of preserve themselves in particular plant habitats. In different phrases, the smaller the dimensions, the higher the possibility of surviving these environments,” he explains.
Other discoveries and historic significance

Ibira was as soon as the birthplace of different species of dinosaurs. One of them was Thanos Simonattoi, a predatory species whose fossils have been found in the municipality in 2018.
In 2020, a turtle with a size of 15-20 centimeters was additionally found in the town, which lived with hungry dinosaurs and crocodiles.
In this regard, Viriato mentioned that the municipality has plans to determine its personal museum in the town, particularly in Vila Ventura, the place most of the fossils have been found.
“We utilized in the state of São Paulo to show a disused college constructing right into a metropolis museum as a technique to improve tourism in the area,” he says.
See the dinosaurs found in the world
Titanosaurus: was a herbivorous animal over 20 meters lengthy. The fossils have been found in the northwestern area of São Paulo, which is the museum’s largest assortment. Its neck and tail are elongated, it roams the entire area in search of meals.
Megaraptor: acarnivorous animal and was about 10 meters tall. Vertebral bones and probably tooth have been found in the Ibira area. It was the highest of the meals chain in the world and had robust claws.
Thanos Simonattoi: A distant relative of the T-Rex, it was about 5 meters tall and was a predator. Vertebral bones found in Ibira. His entrance legs have been very quick.
Maniraptor: one other predatory animal and was about two meters lengthy. Unlike different dinosaurs, this one was coated in feathers. Teeth and vertebrae have been found all through the world.
Other animals: In addition to dinosaurs, different animal species lived in this space, corresponding to prehistoric fish and crocodiles corresponding to baurussuchids, peyrosaurids, and sphagesaurids.
