    • Diagnosis: Lower dentition i4, c1, p5, m6 (Fig. 2). Castorocauda lutrasimilis has the typical docodontan molar features in molars 3 to 6 but is distinguishable from other docodontans by the mediolaterally compressed molars 1 and 2 with slightly recurved cusps in alignment In mandibular length, C. lutrasimilis is about twice as large as Docodon, the next largest docodontan.
