Leptictis acutidens (Leidy 1868, Rose 2006, Novacek 1986, early Oligocene) is an extinct elephant shrew nesting basal to Holmesina. The tiny manus appears to have only three digits, but the medial and lateral digits were tiny and may have been lost during retrieval. Note the large calcaneal heel, a trait usually found in digitigrade running mammals, but also found in armored Holmesina.
The anterior palate view (above shows vestigial canines (in orange) followed by canine-like premolars. |
