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.

The information comes from analysis that has been occurring for the reason that 90s and was revealed final Thursday (15) in a world 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 principle precursor of the invention, gave detailed details about the work carried out by the researchers.

“Collections started in 1999, the identical yr 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 answerable for discovering the fabric in Vila Ventura, the place the work was achieved.

“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 yr that he observed some traits of the fossil and realized that it could be a brand new species.

“When we acquire any fossil, we examine it with comparable objects. If we discover one thing else, we’ll look deeper if it could be 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 other than others.

One of them is the “Iberian fool” steered hyperpneumatization of their axial skeleton, that 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.

While this species proved to be smaller than different titanosaurs, what shocked the group was its measurement, which, whereas classifying it as a “dwarf”, additionally indicated that it belonged to the titanosaurian sauropod household till now. Not registered in America.

“Dwarf titanosaurs have been recorded in some components of Europe since 1915. But the continent was an archipelago, so the confinement between them pressured these animals to be small as a result of downside 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 know 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, similar to shrubs.

Also, in the course of the Cretaceous interval, when “Iberian fool” 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 could be extra resilient as a result of they may take up fewer assets and survive in sure plant shelters. 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 ascertain 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 solution to improve tourism in the area,” he says.

See the dinosaurs found in the realm

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 presumably enamel have been found in the Ibira area. It was the highest of the meals chain in the realm and had sturdy 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 brief.

Maniraptor: one other predatory animal and was about two meters lengthy. Unlike different dinosaurs, this one was lined in feathers. Teeth and vertebrae have been found all through the realm.

Other animals: In addition to dinosaurs, different animal species lived in this space, similar to prehistoric fish and crocodiles similar to baurussuchids, peyrosaurids, and sphagesaurids.
