---|---|---|
K. Suraprasit et al. 2014 | Large-sized Lagomeryx with a long pedicle. Protoantler size is large relative to that of the pedicle. The base of the pedicle has a subtriangular cross-section, becoming oval in its middle part. The shaft of the pedicle curves anteriorly while bending posteriorly and outward (Fig. 2A–C), similar to those of Ligeromeryx. The construction pattern of the protoantler is multibranched, instead of multipointed. The palmate antler consists of six tines at least, probably varying from 10 to 12 tines in adults (Fig. 2M), without a protoburr. The projecting tines display different orientations, varying from horizontal for the anterior tine successively up to 90° for posterior branches. The central valley of the palm portion is flattened. The posterior part of the palm portion is slightly higher than its anterior part. The protoantlers are clearly larger than those of the European Lagomeryx: Lagomeryx parvulus and Lagomeryx ruetimeyeri. It further differs from European Lagomeryx in having a multibranched pattern and a larger protoantler relative to the pedicle size. It differs from Ligeromeryx in having a true palmate antler and an oval cross-section of the pedicle. The number of branches (tines) is higher than those of other species of Lagomeryx and Ligeromeryx, at least one side (half) of the palmate antler bearing approximately six tines. |
