History and classification

The species is one of six Pachycondyla which have been described from Messel Formation fossils. All six of the species were described by Dlussky and Wedmann in the same 2012 paper, the other five being P. eocenica, P. lutzi, P.? messeliana, P. parvula, and P. petiolosa.[1] Another eight fossil species have been described from fossils in North America, Europe, and Asia.[3]
Description
The Pachycondyla petrosa fossil is possibly either a queen or worker and preserved in lateral positioning.[1] The ant has a body length of approximately 12.4 mm (0.49 in) and the head is 2.55 mm (0.100 in). The alitrunk is 3.25 mm (0.128 in) long, with the ant being described as being very similar to members of the genus Mesoponera, formerly considered a subgenus of Pachycondyla. Where preserved the generally triangular mandibles have large blocky teeth and comprise less than half the length of the head. The petiole is a triangle in side view, with a high scale, and a rounded apex.[1]
