types of fossils in excellent state of conservation in the region, were fossils of mollusks, vegetables and vertebrates dating from 65 to 72 million years. There was a theory that the excellent state of conservation of fossils is due to the fact that the bones of the animals were transported by streams to the bottom of the lakes and impregnated in the abundant calcium carbonate of the water, which helped to protect them against the action of time. There are also theories that say that the region's climate may have interfered with fossil conservation, research has said that since the climate at the time was semi-arid, if the animals' bones had stayed outdoors, they would soon become mild, porous and brittle. Among others.

The museum
Upon arrival at the museum, visitors are faced with a huge replica of a herbivorous dinosaur, the work of the artist and sculptor Northon de Azevedo Fenerich. In the showroom there are dozens of replicas and illustrations that together with the fossils show details and characteristics of each animal, plus a glass wall showing the laboratory where the research and cleaning of the fossils are done. In the year 2014 were added 6 new replicas to the exterior of the building . Peirópolis has several types of fossils, including: An almost complete carapace of a small tortoise, small lizards, of iguanas (Pristiguana brasiliense), two species of crocodiles (Uberabasuchus and Peirossaurus), Sauropodes (Uberabatitan rebeiroi), Teropodes and Velocipaptorideos among others

The museum's greatest attraction is the rich collection of fossils of dinosaurs and other vertebrates. It also has explanatory panels on the evolution of life and dioramas that reconstitute the life scenarios and the animals and vegetables that inhabited the Uberaba region millions of years ago. It is installed in the building of the old railway station of Peirópolis, built in 1889, in English style.
