An international paleontological team has described a new sauropodomorph dinosaur species from Zimbabwe, designated Musango matusadonaensis, based on fossil material recovered from sites near Lake Kariba. The specimen, an incomplete skeleton found along the Nyamasango River, represents a bipedal creature approximately 4.5 meters in length that weighed roughly 220 kilograms and died as a subadult during the Late Triassic period, around 210 million years ago.
The discovery emerged from fossils collected during expeditions in 2017 and 2018 to remote sites within Matusadona National Park, accessible only by houseboat. The research team, led by paleontologist Jonah Choiniere of the University of the Witwatersrand and comprising South African, Zimbabwean and UK-based specialists, has conducted extensive analysis of material excavated from ancient river deposits consisting of brick-red mudstones and sandstones. Geological and paleobotanical evidence indicates the Late Triassic landscape featured dry conditions with scattered conifer stands and riparian vegetation corridors.
The analysis yielded an unexpected finding: the dinosaurian fauna of Zimbabwe appears distinct from contemporaneous South African assemblages, contrary to longstanding scientific assumptions. Rather than representing extensions of better-documented South African species, Zimbabwean material includes unique taxa including Musango and the previously described Musankwa. The sites have also yielded non-dinosaurian fossils including lungfish and phytosaurs that are rare or absent in equivalent South African deposits.
Researchers attribute these faunal differences to climatic variations stemming from Zimbabwe’s more equatorial position relative to South Africa during the Triassic. Reexamination of historical collections from earlier excavations near Bulawayo appears to confirm that many previously classified South African species designations are incorrect. Future paleontological efforts will focus on collecting additional fossils and refining chronological and environmental data to better understand early dinosaur evolution and the paleoecology of the African Triassic.
