During a scientific mission in Patagonia, researchers from the Conicet discovered a nest of carnivorous dinosaur eggs at a site in Río Negro. The discovery, presented live through the organization’s streaming channel, became one of the most exciting moments of the “Cretaceous Expedition I – 2025”.
The team, consisting of fourteen specialists, has been working since the end of September in an area near General Roca. There, among Cretaceous sediments, paleontologists found several eggs in excellent state of preservation, some with the possibility of containing fossilized embryonic remains. This type of discovery is exceptional, especially in South America, where almost no complete nests of carnivorous dinosaurs are recorded.
The finding not only provides information about the biology of these animals but also about their behaviors. Scientists highlight that nests are a “biological footprint”, capable of revealing aspects such as how they nested, protected their young, and interacted with the environment.
The best-preserved egg, with characteristic dinosaur ornamentation, was shown to the audience connected to the streaming. The moment, broadcast live, combined the excitement of the discovery with scientific dissemination open to the public, one of Conicet’s main commitments in this campaign.
Live Science: Conicet’s streaming brings paleontology to the public
The “Cretaceous Expedition I – 2025” marks a new step in the way of communicating Argentine science. Through the YouTube channel @paleocueva_lacev and the Instagram account @paleocueva.lacev, the public can follow the researchers’ work in real-time. Broadcasts are held in two time slots —from 11 to 12:30 and from 17 to 18:30— between October 6 and 10.
Each broadcast allows viewers to observe how paleontologists excavate, analyze samples, and explain the processes behind each discovery. The proposal combines science, education, and entertainment, showcasing the human and collaborative side of field research.
This initiative follows the line of other Conicet experiences that have embraced the live format, such as missions at the bottom of the sea or broadcasts from marine biology laboratories. On this occasion, the fossil jungle of Patagonia becomes the stage for an exploration that, besides rescuing remnants of the past, seeks to inspire new scientific vocations.
The project is supported by National Geographic Society, the Félix de Azara Natural History Foundation, and the Secretariat of Culture of Río Negro, in a joint effort to disseminate Argentina’s paleontological heritage and promote environmental awareness.
Patagonia, cradle of Cretaceous secrets
The Patagonian region is recognized as one of the richest fossil deposits on the planet. There, remains of reptiles, amphibians, primitive mammals, and unique dinosaurs have been identified. The team led by Federico Agnolín, leader of the expedition, works in the same area where in 2024 the claw of the Bonapartenykus ultimus, an endemic carnivorous dinosaur of Argentina, was found.
The new finding reinforces the importance of protecting these sites and continuing with research that provides knowledge about the evolution and biological diversity of the past. Each fossil found not only reveals fragments of a lost era but also helps to understand how environmental changes shaped life on the planet.
With this expedition, Conicet reaffirms its commitment to making science accessible, rigorous, and connected with society. The live broadcast of paleontological findings thus becomes a powerful tool to bring scientific knowledge closer to new generations and strengthen the link between research and ecological awareness.
