Bramiscus micros
Taxonomy
Bramiscus micros was named by Ríos et al. (2024) [The specimens are stored at the Dr. Abu Bakr Fossil Display and Research Centre, University of the Punjab, Lahore, Pakistan (PUPC IDs) and Harvard Peabody Museum, USA (Y-GSP IDs). The material of the new species is also represented in the Harvard-GSP project (Y-GSP) collections and
belongs to the Geological Survey of Pakistan. While the final deposition of the fossils is uncertain, they currently are all at Harvard Peabody Museum
in the Department of Human Evolutionary Biology’s Paleoanthropology Lab. (as of 19/07/2024)]. Its type specimen is PUPC 22/01, a partial skull (fragment of frontal bone bearing a pair of ossicones with their fused bases (Figure 3).), and it is a 3D body fossil. Its type locality is Dhok Bun Ameer Khatoon, which is in a Miocene floodplain mudstone/sandstone in the Chinji Formation of Pakistan. It is the type species of Bramiscus.

Diagnosis

|---|---|---|
| M. Ríos et al. 2024 | Small-sized giraffid with probably two pairs of ossicones. The ossicones of the anterior
pair are fused at their base (Bramatherium-like). The posterior pair is straight and possibly directed laterally. All ossicones have an oval cross-section at the base and are vaguely circular at the apex. The ossicone surface is covered with longitudinal ridges of medium depth. The ridges or grooves are deeper and larger distally on the apical part and laterally than dorsally on the proximal part and medially. The dentition is brachydont and shows a rugose enamel. The upper molars have a post-metaconule fold and a labial cingulum, as well as a developed entostyle. The lower p2 has a crest on the anterior valley. The lower p3 has a well-developed paraconid and parastylid. The metaconid is narrower than the entoconid. The lower molars have a slightly rounded protoconid and hypoconid. Labially, they have rugose enamel and an anterolabial cingulum. A Palaeomeryx fold of the lower molars is absent (sensu Sánchez et al., 2011). The lower molars have a high L/W index of ~2. The metatarsal has a characteristic large medial ridge and a low lateral ridge. |
