The province of Corrientes entered the fossil record of dinosaurs for the first time with the discovery of a titanosaur, a giant herbivore from the distant past.
The material was found in cretaceous sediments between the towns of Mercedes and Curuzú Cuatiá, in an area little explored until now.
This discovery decisively expands the knowledge about the natural history of northeastern Argentina.

The fossil that opened a new stage
The identified remnant corresponds to an osteoderm, a bony plate that was part of the skin of certain titanosaur sauropods.
The element was recovered during a scientific prospecting campaign and analyzed for almost two years by an interdisciplinary team.
Comparative studies and microtomography techniques allowed it to be linked with titanosaurs from the southern hemisphere.
A giant from the past in Corrientes lands
Titanosaurs dominated the Cretaceous ecosystems, playing a key role as large herbivores. Their presence suggests environments rich in vegetation and favorable ecological conditions for large-sized fauna.
This record connects Corrientes with neighboring regions that already had similar evidence. Until now, the oldest fossils in the province corresponded to much more recent mammals.
The discovery pushes the local vertebrate record millions of years back in time. This opens new lines of research on the evolution of NEA ecosystems.

Contributions of this discovery to environmental knowledge
The discovery strengthens the scientific value of the territory and stimulates the protection of areas with fossil potential.
It also promotes environmental education, bringing the community closer to the deep history of the landscape they inhabit. Furthermore, it reinforces the idea that conserving the soil is preserving key information about life on Earth.
Science, conservation, and future
The first dinosaur of Corrientes is not just a scientific fact, but an opportunity to think about development from knowledge.
Researching, protecting, and disseminating these findings promotes a more responsible connection with the environment. Each recovered fossil reminds us that current biodiversity is the heir to a history that deserves to be cared for.
