Diagnosis

|---|---|---|
| G. W. Rougier et al. 2009 | Measurements. MML- Pv 10 (Lm
¼ 4.05 mm; Wm ¼ 5.29 mm); MML-Pv 11 (Lm ¼ 4.05 mm; Wm ¼ 5.62 mm); MML-Pv 12 too fragmentary for meaningful measurements. Groebertherium stipanicici is a small-sized dryolestoid, with a stylocone divorced from the paracrista and a long, narrow trigon. The molars have a tall crown, they are approximately symmetrical and devoid of cingula. The parastyle forms a small hook. A centrocrista is poorly defined and, if at all present, represented by the thick lingual extension of the lingual slope of the stylocone. |
