Yuezhuornis

Common card · No. 415025

Yuezhuornis (lit. 'Yuezhuo bird') is an extinct genus of basal avialan known from the Late Jurassic (Kimmeridgian–Tithonian ages) Nanyuan Formation of China.The genus contains a single species, Yuezhuornis yangyuanensis, known from a partial skeleton and skull. It has significantly shorter arms than its closest relatives—being proportionally more similar to many non-avialan theropods—implying it was incapable of flight. It was a close relative of Zhengheornis, which is known from the same locality.
