A group of scientists from the University of Chile have discovered fossils

With this project, a team of researchers has given a new impetus to the national archeology, which has fueled discoveries about the time in a few years when the Daily Dessource ruled Chile. The work, published in international scientific journals, reveals the vastness of fossil records in different parts of the country and the evolutionary history of indigenous animals over a period of about 250 million years.

In contrast to what was considered a few decades ago, Chile was an area inhabited by a variety of dinosaurs. The largest landmark to date in this area has been the discovery of the Chalceurio, in Eisen in 2004, an herbal thread - similar in speed but smaller and with a horned beak - which gave a real evolutionary imprint. Revolutionized the scientific world by representing . The discovery of this dinosaur, which predates the Jurassic period found on Chile's mainland, has since attracted the interest of many researchers and represented an unprecedented development for the national biologist.

In 2015, this species, which lived in our country more than 145 million years ago, was scientifically named in the journal Nature. The scenario was a precursor to the progress of the Color of Consensus project "Fossil Records and Evolution for Status", which brings together scientists from the University of Chile, the Museum of Natural History and the Chilean Antarctic Institute (INAC) since 2018. In a few years, the initiative has led Chile to become one of the world's leading dinosaur researchers, with journals such as Nature Ecology and Evolution, Journal of Wetterbright Paleontology, Frontiers Zoology and Cretaceous Research. Other posts include.

Dinosaurs in Chile

Kalma, Copia, Caldera, Algarrobo, Concepcion, Constance, Patagonia and Antarctica have been part of its search and extraction points. The most relevant search to date is located on the coast of the Boombao region, near Tome, an area rich in marine silk fossils. This space allowed, for example, the first detailed description of the skeleton of Aristocrat Curiosity, which still exists (10 to 12 m) in a large plasmosaurus, whose limbs are 3 m and very fine. Can measure teeth. Researchers - Serve as a filter feeder for organisms such as small curls. Work on the species, led by pathologist Rodrigo Otero of the University of Chile, was published in 2018 by the Journal of Vertebrate Paleontology.

Fossil remains of a hyssop have also been found in the area, a discovery that established the first such cassava in Chile. The species was a sea lizard three to four meters long, resembling a dolphin, with narrow wings and large eyes, which were mostly smaller than other lizards.

Another recent milestone for the group was the discovery of the first remnants of the Temnodontosaurus in the Southern Hemisphere, a class of Actiosaurs that inhabited the Atacama Desert in the desert 200 million years ago today. The remains of this seabird, twelve meters long and seven centimeters in teeth, were unearthed near Antofagasta in 1988 by geologist Patricio Ceploida of the University of Chile, but more than 30 years later the species was identified by Rodrigo Otto. In the area, the team has discovered new fossils of marine reptiles from the Jurassic period.

Field campaigns have also made it possible to identify the rest of Petrosour in the north of the country. A study by Chilean University expert Jhanatan Alcan has allowed the fossils to be located at an altitude of about 3, 3,600 meters in the mountain range, 30 years ago, at a height of Chashmal. Cenotaphs is from a parsor of the family, due to its characteristics, it will be the first of this indigenous group in our country. This flying creature, which lived about 150 million years ago, could measure one and a half meters in height and reach up to three meters in width with outstretched wings, which penetrated a membrane through the fourth finger of its hands. The source was created. Near the word, meanwhile, are found sketches of a type of pterosaur of Renfranco, a long and hard-tailed wood with a diamond-shaped tip. It had pin-shaped teeth as before.

In the Seguro Guido, Megalins region, about 70 million years ago, fossils of rich animals and dinosaurs, which inhabited South America, have also been found since the separation of the Gondwana subcontinent (the ancient super continent of the south). Fossils of the titanosaurus, a long-necked herbivorous dinosaur measuring 9 to 12 meters in height and weighing about 13 tons, have been found at this site near Las Torres del Penn. Larger Dinosaurs The site also features a large concentration of hydrosaurus fossils, known for its beak like the herbivorous dinosaur duck that inhabited the area about 70 million years ago - the late Cretaceous region. I was settled 6 and 12 meters long. Working in the area has allowed researchers to promote the technological study of the species that inhabited the area.

Evolutionary results


Under this project, under the leadership of Professor Alexander Vargas, the Paul Robert Laboratory at the University of Chile was also implemented, a place that today serves as a practical center for the study of dinosaurs and other fossil fossils by numerous researchers and students.

Here is some very effective research. One of these works has made it possible to identify the "inner dinosaur" in birds from the two bones that surround the dinosaur's eyes, and it can still be found in embryonic birds. This evolutionary search was published by Nature Environment and Evolution.

Another study by this group revealed an inverse relationship between the size of carnivorous therapods that inhabited the Jurassic, such as cruelty and barbarism, and the proportion of their arms. The work, in other words, says that as big as the dinosaur is, as small as its wings, it was published in the scientific journal Frontiers in Zoology.

During this time, new breeds of ancient animals inhabiting our country were also discovered. One of those found was the Loncorn chains caterpillar, a type of swordfish that lived about 40 million years ago, on the coast of the Maule region, and was killed by the so-called Biper eros, Camilo caterlinka, Caribbeans. Tribute was paid to the young man.

The record for the new species includes a stingy one that inhabited the central part of the country about 66 million 66 million years ago, Meladophos aurochs, the first of its kind found in the southern hemisphere. For this year, finally, the team of archaeologists creates many surprises about the time when dinosaurs ruled in Chile.

Completing knowledge


Developed from the fossil record found in the country, this research has allowed the team to develop a variety of formal materials, including the appearance of dinosaurs, reptiles and mammals that inhabited our country millions of years ago. Offers the work is primarily the work of science painters Mauricio Alvarez and Luis Perez, who have participated in the project in the past with numerous graphic exhibitions focusing on the specific shapes and details of these animals.

Reconstructing and analyzing the bone remains, he created 3D images and skeletal replicas to spread the history of dinosaurs, mammals and animal life in Chile. Leading researcher from the National Museum of Natural History's project, David Rubilar won a FONAPI competition that allowed him to create 3D prints of dinosaur fossils for workshops in schools for visually and hearing impaired children. "We have been able to capture other activities, such as the Cerro Nova Jurassic," said Professor Vargas.
