---|---|---|
E. Gheerbrant et al. 2018 | S. minor shares with the Embrithopoda the hyperdilambdodont morphotypic molar pattern. It differs from all known embritho- pods, including Palaeoamasia, by its very small size and prim- itive state of hyperdilambdodonty, with less lingual paracone and metacone and correlatively shorter pseudolophs (prepara- crista, premetacrista) and with retention of more developed postparacrista, postmetacrista, and pseudohypocone; cheek
teeth with brachyodont low crown; M1–2 with one lingual root and with separated paracone and protocone roots; P2 single- rooted and simple; and P2 double-rooted and simple. Anterior incisors are enlarged (especially their root), and I1 is partially hypsodont. |
