Musankwa
Named for the houseboat 'Musankwa' that served as the paleontologists' laboratory and home during fieldwork; 'musankwa' is a Tonga word meaning 'boy close to marriage'.
Musankwa is an extinct genus of plateosaurian sauropodomorph dinosaurs from the Late Triassic (Norian) Pebbly Arkose Formation of Zimbabwe. The genus contains a single species, Musankwa sanyatiensis, known from an incomplete hindlimb. Musankwa represents the fourth dinosaur genus to be named from Zimbabwe.
Under dispute
Every analysis to include Musankwa sanyatiensis has placed it differently. Barrett and colleagues (2024) recovered it as the earliest-branching massopodan, sister to Riojasauridae and all later-branching massopodans. Wang and colleagues (2025) instead recovered it in a trichotomy with Macrocollum and Pradhania at the base of Massopoda, and Barrett and colleagues (2026) recovered it as the sister taxon of the sympatric Musango within Unaysauridae, which falls outside Massopoda in their strict consensus but within it in some of their most-parsimonious trees. Support is weak throughout: the Musango–Musankwa pairing rests on a single highly homoplastic astragalar character at a Bremer support of 1, and its describers caution that the relationship is unlikely to prove robust as new material comes to light. Plateosauria is the least-inclusive clade that all three analyses accept.
Diagnosis
- Prominent posterior tubercle on proximal femur margin
- Proximal femur shaft anteroposteriorly expanded and swollen at anterior trochanter level
- Fourth trochanter base straight, centered on posterior femoral surface, confined to proximal half of shaft
- Fibular condyle separated from cnemial crest by distinct sulcus
