Djurab Desert (Miocene of Chad)

Where: Chad (12.4° N, 15.2° E: paleocoordinates 12.2° N, 14.6° E)

When: Toros Menalla Formation, Late/Upper Miocene (11.6 - 5.3 Ma)

• The fossils from Toros Menalla (Anthracotheriid Unit) are found in layers which are dated to the Late Miocene (ca 7 Ma) by a biochronological approach (Vignaud et al., 2002) and radiometrical data as well (Lebatard et al., 2008).

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils

• The anterior part of the mandible is broken off and thus we cannot know exactly the shape of the mental area but there was not a large downwards directed mandibular flange. The horizontal ramus is shallow.

• The coronoid process, whose tip is just a little eroded, is very low like those of much derived machairodont (Homotherium or Megantereon) but it is apparently not hook-shaped like in Megantereon ekidoitWerdelin and Lewis (2000, 2002). The condyle is partially broken and clearly situated below the level of the cheek teeth cervix.
