Pterosaur is the first group of vertebrates with powered flight. It originated in the Late Triassic and became extinct with dinosaurs (excluding birds) at the end of the Cretaceous. Various diets of pterosaurs were proposed using different interpretations, such as content fossils and comparative anatomy. However, the understanding of the diets of many pterosaurs have still been on debate, which is mainly because of the rarity of stomach content found in pterosaurs. In this paper, the researchers found an elliptical content in the stomach position of a Sinopterus specimen. They extracted more than 300 phytoliths from the stomach content but none from the matrix of the same specimen. This demonstrates that these phytoliths, firstly appeared in pterosaurs, were eaten by this Sinopterus rather than any pollution after its death. Phytolith is a microstructure produced by all kinds of plants, and it varies among different plants and different positions of the same individual. Besides the phytoliths, many gastroliths (stones within the body cavity) were also discovered in the stomach content, which is the second pterosaur specimen with gastroliths. The combination of phytoliths and gastroliths, without any bones, scales or exoskeletons, strongly suggest that Sinopterus is herbivorous.

An international project led by Hungarian researchers has successfully identified the remains of Duke Béla, the Ban of Macsó, a member of the Árpád and Rurik dynasties. The investigations have answered a century-old archaeological question.

Prof Carla Jaimes Betancourt, an anthropologist focusing on the Amazon, is a researcher at the Department of Anthropology of the Americas at the University of Bonn and co-director of the BASA Museum housed at the university. Her research, promoting collaborative archaeology with local Indigenous People, focuses on the social complexity in the southwestern Amazon and processes of expansion and formation of ethnic groups in the South American lowland.

In a newly published Frontiers in Environmental Archaeology article, she and co-authors present the results of interdisciplinary and collaborative archaeological research conducted in the southwestern Amazon. In the following editorial, she highlights the rich cultural heritage found at the sites and the importance of protecting these landscapes where humans have thrived for thousands of years.

As global oyster populations decline and fisheries collapse, archaeologists may be able to inform effective management with valuable, long-term perspectives of the human-oyster connections stretching back millennia.
