Hallensia aff. louisi

Hallensia sp. – Smith & Hooker 1996: 120-121, fig. 1-2.

MATERIAL. — DP4 (R: IRSNB.M 1795); m1/2 (R: IRSNB.M 1796 [broken]) .

LOCALITY. — Hoegaarden (Belgium), MP8-9.

DESCRIPTION

Teeth

The upper molar cusps are rounded and inflated. The hypoconulid is linked to the hypoconid by a postcristid.The hypolophid is weak.

Deciduous teeth

The DP4 parastyle is poorly developed. The paraconule and the metaconule are developed. The centrocrista is slightly flexed labially. The metaloph joins the metacone. The cingulum runs on the anterior side of the hypocone. A small crest links the metaconule to the protocone.

COMMENT

These remains are very fragmentary (Smith & Hooker 1996). The junction of the hypoconulid with the hypoconid of the molar indicate that it does not belong to the genera Cymbalophus and Orolophus . They correspond in size and morphology to Hallensia louisi, presenting notably “blistered” cusps characteristic of Hallensia .
