    abstract = "The oldest felid specimen in the New World is a cranium from Ginn Quarry, Nebraska. We present a detailed description of the external brain anatomy of this specimen as inferred from its cranial endocast. Compared with modern felids, the Ginn Quarry specimen has a dorsoventrally lower cerebrum, with only three major sulci and a laterally narrower frontal lobe. The cerebellum is exposed to a large extent, and the posterior cerebellar vermis is straight rather than twisted as in modern felids. The shape of its cerebrum and the cortical sulcal pattern are similar to those of Proailurus and Hyperailurictis. The encephalization of the Ginn Quarry felid is the same as that of Hyperailurictis and slightly smaller than in Proailurus. The degree of cortical folding is intermediate between the conditions seen in Proailurus and Hyperailurictis. The Ginn Quarry felid differs from Proailurus in having a better developed frontal lobe, a shorter cerebellum and slightly longer peduncles. Based on brain anatomy, we suggest that the Ginn Quarry felid should not be dismissed as a ‘proailurine-grade’ felid. Instead, it should be either considered a primitive form of Hyperailurictis or assigned to a new genus. © 2019, Paläontologische Gesellschaft."
