Zimbabwe: Zimbabwe's Dinosaurs Were Different From South Africa's - New Species Offers Clues

What the report says

A new analysis published by The Conversation Africa and distributed by AllAfrica says fossil work in Zimbabwe is reshaping understanding of early dinosaur evolution in southern Africa. The piece focuses on Musango matusadonaensis, a newly described sauropodomorph from rocks near Musango Island on the shore of Lake Kariba, in Matusadona National Park. According to the article, the incomplete skeleton suggests a bipedal dinosaur about 4.5 metres long, weighing roughly 220 kilograms, and still juvenile or subadult when it died.

The research team, led by scientists including Jonah Choiniere of the University of the Witwatersrand and collaborators from Zimbabwe, South Africa and the UK, carried out expeditions in 2017 and 2018 and has continued studying the material since then. The fossils come from Late Triassic river sediments laid down around 210 million years ago. The article says the Kariba landscape was likely dry, with conifer stands and greener belts near waterways.

The key finding is that Zimbabwe’s dinosaur fossils appear to be distinct from better-known South African faunas, rather than simply matching them. The article also notes that related work has identified another Zimbabwean dinosaur, Musankwa, from the same beds, and that other fossils such as lungfish and phytosaurs point to a broader mix of animals not seen in nearby South African sites. The authors suggest climate and geography may have helped shape these differences and say more fieldwork is planned to refine the ages and environments of the rocks.
