Extraordinary discovery in Sardinia: dinosaur tracks found during filming of a documentary
During the filming of a documentary on the region's geomorphological landscape, scientists found important palaeontological evidence in the countryside around Baunei, in Ogliastra: fossil traces testifying to the presence of dinosaurs in Sardinia.
The discovery was made by a scientific team composed of professors Antonio Assorgia, Sergio Ginesu and Stefania Sias, former lecturers at the Universities of Sassari and Cagliari.
Preserved in rocks dating back to the Jurassic period, the footprints belong to a theropod dinosaur never previously reported in Sardinia.
Thanks to the extraordinary discovery, it has been possible to reconstruct the animal's appearance and the environment in which it lived. The dinosaur was a biped from the Middle Jurassic period, around 165 million years ago, and lived along stretches of coastline with sandy and muddy sediments, typical of marshy and tidal areas. This was explained by experts at a press conference on Friday.
The rocky surface where the dinosaur's footprints were found also provided evidence of the presence of other coeval species. This is therefore the first evidence of the presence of dinosaurs in the Mesozoic period in Sardinia.
Stefania Salis, the first to notice those tracks, said the dinosaur discovered was named 'Bibi', and would be a female specimen, although we have to wait for scientific evidence to ascertain this.
"The footprints speak to us and tell us how things were 165 million years ago, the one from Baunei was probably a herbivore, given the lack of claws, and was a biped about 120 160 centimetres long," said palaeontologist and lecturer at the University of Sassari, Marco Zedda, speaking at the conference and explaining how from just a footprint, one can reconstruct the animal that left it.
According to Francesco Ginesu, Sole Director of the MGB company and responsible for the production of the documentary, this is an exceptional discovery, and emerged almost by chance. "As often happens in science, it has the power to radically change what we thought we knew," said Ginesu, adding that "those footprints, spotted while working on a popularised product, turned out to be a finding of enormous scientific value. It is not just one more piece of data: it is direct evidence of the presence of dinosaurs in an area that until now had not yielded such clear evidence."

Rare Ceratosaurus fossil sells for $30.5 million
Sign up for CNN's Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. A Ceratosaurus fossil that is one of only four known to exist has sold for $30.5 million at auction. The rare dinosaur fossil is 'one of the finest and most complete examples of its kind ever found,' auction house Sotheby's said in a statement published Wednesday. The specimen, which is the only juvenile Ceratosaurus fossil of the four, sold for multiples of its $4 million-$6 million estimate at Sotheby's New York following a six-minute battle between six different bidders. Ceratosaurus nasicornis was a meat-eating predator with a nasal horn, long teeth and bony armor that ran down its back and tail. Standing six feet, three inches (1.9 meters) tall and approximately 10 feet, eight inches (3.25 meters) long, this juvenile fossil is made up of 139 bone elements, of which 57 make up 'a superb virtually complete skull,' according to Sotheby's. It was found in 1996 at Bone Cabin Quarry in Wyoming and dates from the late Jurassic period, around 150 million years ago. The fossil was displayed at the Museum of Ancient Life in Thanksgiving Point, Utah, from 2000 to 2024 and has not been studied or described formally in a scientific journal, Sotheby's said. 'The buyer of the Ceratosaurus intends to loan it to an institution, as is fitting for a specimen of this rarity and importance,' the auction house said. In the same sale, a meteorite that is the largest known piece of Mars on Earth sold for $5.3 million. 'These stellar results underscore a deep and enduring fascination and respect for the natural world — from the farthest reaches of space to the ancient depths of the Earth. What draws collectors is more than just a passion for science; it's a deep-seated curiosity about the forces that have shaped our planet and beyond,' Cassandra Hatton, global head of science and natural history at Sotheby's, said in the statement. Mark Westgarth, a professor of history of the art market at the University of Leeds, England, told CNN that the sale 'is part of a recent resurgence of interest in fossils and natural history.' For example, Sotheby's also sold the most valuable fossil ever sold at auction, Apex the Stegosaur, which fetched $44.6 million in July 2024. 'At the top end of the market … seems to be about an increasing desire for 'distinction,'' said Westgarth. 'These dinosaur specimens also have a particular aesthetic — they are sculptural and awe inspiring.' For Steve Brusatte, a professor of paleontology and evolution at Scotland's University of Edinburgh, these kinds of price tags are shocking. 'Who has that kind of money to spend on a dinosaur? Certainly not any museums or educational institutions,' he told CNN. 'While I'm pleased that the buyer might loan the skeleton to a museum to be put on display, at this point it is just a vague suggestion. The buyer is still anonymous,' Brusatte added. 'My fear is that this skeleton will disappear into the ether, into the mansion of an oligarch or a bank vault to accumulate value as just another investment in the portfolio of a hedge fund, and not see the light of day until it's auctioned again, or maybe never at all,' he said. 'Bottom line, a world where dinosaur skeletons can fetch tens of millions of dollars within a few minutes at auctions is not a world where dinosaurs will long be accessible to educate and inspire everyone,' Brusatte added. However, Westgarth argues that there is a 'symbiotic' relationship between the market and wider research interests. He cites the example of Mary Anning, who discovered fossils on England's south coast in the early 19th century and went on to open a successful fossil shop. 'Here the market for fossils acted as a catalyst for research in public institutions in the 19th century, inculcating increasing attention and public interest and acting as a catalyst for increased research activity on dinosaur fossils,' said Westgarth, who argues that the fact that the buyer of the Ceratosaurus fossil 'has suggested that they will loan it to an institution only adds to its potential for future research activity.'

Prehistoric ‘scalopini' mole fossil uncovered in an ancient Spanish volcano crater
Researchers have discovered a new genus and species of prehistoric mole in Spain. Vulcanoscaptor ninoti lived during the Pliocene Epoch, from 5.3 to 2.6 million years ago and belonged to the Scalopini, a tribe of moles that currently exists in North America and Asia. Before we dive into the details of a discovery, there is one matter we should immediately set straight. If 'Scalopini' sounds familiar, you're probably thinking of scallopine, or scallopini—a delicious Italian dish consisting of thin sautéed slices of meat served in a variety of sauces. Needless to say that the food scallopine will (unfortunately) not be playing a large part in this story. Researchers found V. ninoti in an excellent state of preservation, recovering its mandible with a complete set of teeth, sections of the torso, and a number of leg bones in their correct anatomical connection. The specimen represents one of the oldest and most complete small mammal fossils in Europe, as they explain in a study recently published in the journal Scientific Reports. The team examined the delicate remains via high-resolution micro-computed tomography (microCT) scanning, which generated a 3D reconstruction of the skeleton. 'With the microCT, we were able to analyze extremely small and delicate structures—such as phalanges and teeth—that would have been nearly impossible to study otherwise,' Adriana Linares, lead author of the study and a predoctoral researcher at the Universitat Rovira i Virgili, explained in a statement. While the anatomy of the fossil indicates that the animal was a strong digger and highly adapted to an underground lifestyle, 'the fact that this individual was preserved in lacustrine [lake] sediments and in a lateral position raises the possibility that it may also have had some aquatic locomotion abilities,' Linares added. 'We can't confirm this with certainty yet, but there are modern moles that are powerful diggers and also excellent swimmers.' The name Vulcanoscaptor ninoti means 'the Camp dels Ninots volcano digger' in reference to where it was discovered. Camp dels Ninots is an important paleontological site in the crater of an ancient volcano near Girona in northeastern Spain. An eruption about 3.1 million years ago created ideal conditions for the preservation of fossils. In fact, the researchers claim that V. ninoti is also the most complete known Pliocene mole fossil from Europe, presenting an excellent opportunity to investigate the evolutionary history of the small mammals. [ Related: These moles may have been hiding for 3 million years. ] 'Despite its clearly fossorial morphology, this mole is closely related to extant North American species of the genera Scapanus and Scalopus, which points to a far more intricate evolutionary history for these animals than we had imagined,' said Marc Furió, co-lead of the study and a geologist at the Universitat Autònoma de Barcelona. 'Its presence in Europe suggests past transcontinental migrations of moles, challenging the assumption that they are mammals with low dispersal capacity.' It seems like both prehistoric and modern mole species still have a lot of surprises in store for paleontologists. Solve the daily Crossword
