Uberaba Geopark: A time capsule from the Late Cretaceous period nestled in Brazil's tropical savanna

The Uberaba Geopark, also known as Terra dos Gigantes or Land of the Giants, is a remarkable time capsule nestled in Brazil's tropical savanna. Located in Minas Gerais, the park lies within the Cerrado biome, the second-largest in South America after the Amazon rainforest. The geopark is renowned for its abundant, well-preserved fossils from the Late Cretaceous period, which spanned from 100.5 million to 66 million years ago.

The park is home to over 10,000 fossils, including dinosaur remains, prehistoric crocodyliforms, turtles, and other ancient creatures. One of the most notable discoveries is the Uberabatitan ribeiroi, a titanosaur that measured an impressive 89 feet (27 meters) in length and 33 feet (10 m) in height. These fossils were found in geological features such as the Serra da Galga formation and the Serra Geral mountain range, which were formed from ancient basalt flows following giant volcanic eruptions.

The unique conditions in the Uberaba Geopark, which alternated between shallow lagoons and river systems during the dinosaur era, allowed for the preservation of animal remains in mud when they died. Additionally, the geopark is situated near one of the world's largest freshwater reservoirs, the Guarani aquifer, which provides drinking water for over 100 cities in Brazil, Argentina, Paraguay, and Uruguay.

The Uberaba Geopark was designated a UNESCO geopark in 2024, recognizing its geological and natural heritage. The park is open to visitors and offers several museums, trails, and unique locations like the Enchanted Valley, which features forests, waterfalls, and prehistoric rock formations. The land was once the birthplace of Brazil's modern livestock market, with zebu (Bos indicus) cattle introduced from India for their adaptability to the climate and lower greenhouse gas emissions compared to Bos taurus cattle.
