This study was carried out with the objective of determining the antioxidant properties and quantification of total phenolics and flavonoids in relation to quercetin and rutin in some of the monofloral honeys produced in Minas Gerais (Brazil). In this study, 15 monofloral honey samples were obtained from different geographic regions of Minas Gerias, Brazil. The honeys were obtained from Cooperative of Beekeepers and Family Farmers of Northern Minas. To determine the antioxidant properties of honey samples, the test methods of total phenolic content, flavonoids (rutin and quercetin) and DPPH were used. As a result of the analysis of phenolic and flavonoid contents, the samples with the best results were A1-Aroeira and A4-Assa peixe. In antioxidant activity, the honey with the best EC50 results was A6-Aroeira. Differences between the antioxidant activities of the honey samples were found significantly (p< 0.01).

Two specimens of Campinasuchus dinizi (CPPLIP 1319 and CPPLIP 1360) belonging to Baurusuchidae (Crocodyliformes, Notosuchia) from the Upper Cretaceous Bauru Group of Minas Gerais state (Brazil) were scanned in a Toshiba Aquilion 64 CT machine. Based on these data, it was possible to identify and reconstruct the paranasal sinuses, the nasal cavity proper, the nasopharyngeal duct, the encephalon, the paratympanic sinuses, and the semicircular canals of the inner ear. The paranasal sinuses present similar morphology to those of other mesoeucrocodylians, especially eusuchians. The nasal cavity proper occupies the entire rostral region, with an expansion in the olfactory region. The expansion in the nasal cavity is present in other notosuchians and theropod dinosaurs (e.g., Tyrannosaurus rex Osborn, 1905), but less developed in aquatic crocodilians, which may indicate an olfactory acuity related to terrestrial habits. The encephalon is similar in shape to that of other mesoeucrocodylians. The rostral semicircular canal is smaller than the caudal one, differing from most mesoeucrocodylians. The paratympanic sinuses are more developed in C. dinizi than in eusuchians, being more similar to Tyrannosaurus rex. Campinasuchus dinizi presents few variations in the internal structures of the skull in relation to taxa with different ecological niches, probably indicating that ecological factors do not strongly influence the morphology of these structures.

Tooth marks on sandstone in an area of the Cerrado Biome are reported, indicating geophagy. The tooth marks were found on reddish sandstones cropping out in a pasture environment with typical components of the Cerrado Biome, in the Municipality of Campina Verde, Triângulo Mineiro region (west Minas Gerais State, Brazil). Studies have shown that the soil of the Cerrado is acid, with a low concentration of nutrients and minerals (also present in the plants living on this environment), which usually produce an alimentary deficiency in herbivorous animals. Therefore, these tooth marks indicate geophagy, in order to extract extra minerals from these sandstone levels, which have a high concentration of calcium carbonate and iron. The tooth marks consist of two parallel concave grooves and a medial prominent crest which results from the action of the incisors of mammals. Although the identification of the gnawing species for these sets of tooth marks are estimates at best, after wide comparisons we tentatively suggest that the tooth marks are most likely the result of the action of the incisors of rodents, such asDasyproctaorCoendou.

This article discusses the giant armadillo also named as Priodontes maximus (Dasypodidae) at the private reserve located in southeastern Brazil, Reserva Particular do Patrimônio Natural Vale Encantado. The authors comment on the burrows reported in the reserve, the weight and height of the armadillo and the significance of wildlife conservation in Minas Gerais, Brazil.
