Fig. 8 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 8. Rostral entotympanic fused to the inner margin of the ectotympanic in Prionodon (AMNH 163595), medial view, ventral at top. Dashed line indicates path of the internal carotid artery within the ventral edge of the rostral entotympanic.
Fig. 7 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 7. Dissection of the auditory region of Prionodon pardicolor (AMNH 163595) in oblique lateral view. The posterior chamber of the bulla has been opened (A), revealing the inflected dorsal margin of the caudal entotympanic applied to the petrosal, and the ectotympanic resting on the promontorium anterior to the round window. Removal of the ectotympanic and rostral entotympanic (B) allows an unrestricted view of the petrosal promontorium with its robust ventral process forming an incipient flange buttressing the edge of the basioccipital. Note that the caudal entotympanic covers the ventral process of the promontorium when in place.
Fig. 4 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 4. The basicranium of Palaeoprionodon (MNHN Qu 9348) from Quercy: (A) ventral, (B) posteroventral, and (C) posterolateral views. In (B) small black triangles indicate line of attachment of the caudal entotympanic to the margin of the petrosal. For abbreviations in this and subsequent figures, see pages 3–4.
Fig. 3 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 3. Skulls of the Asian linsang Prionodon pardicolor (AMNH 163595, above) and African linsang Poiana richardsoni (AMNH 51438, below) in lateral view. Figures 3–10 are stereophotographs.
Fig. 6 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 6. Basicrania of Prionodon (AMNH 163595, A) and Poiana (AMNH 51438, B) in ventral view. The bony floor of the posterior chamber of the auditory bulla has been removed on one side in each individual to show the ectotympanic resting on the petrosal promontorium, and the size of the posterior chamber formed by the caudal entotympanic. Note the more expanded or inflated posterior chamber in Poiana relative to Prionodon.
Fig. 2 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 2. Skulls of the Quercy Palaeoprionodon (MNHN Qu 9370), the Asian linsang Prionodon pardicolor (AMNH 163595), and the African linsang Poiana richardsoni (AMNH 51438), from left to right. (A) dorsal view; (B) ventral view. Scale bar in this and all subsequent figures is 1 cm.
Fig. 10 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 10. Final stage of the dissection of the auditory bulla of Prionodon (AMNH 163595, A) and Poiana (AMNH 51438, B) in ventral view. Note the robust ventral process of the promontorium in Prionodon, only incipiently modified as a flange appressed against the basioccipital, hence similar to the form of the ventral process in Palaeoprionodon (compare with fig. 4). In Poiana the flange has been further modified as a thin blade and has been extended fore and aft to a greater degree than in Prionodon. The caudal entotympanic is more inflated in Poiana, broadly contacting the paroccipital process, whereas in Prionodon the caudal entotympanic is not as expanded, and the process still retains a vestige of its primitive rodlike form.
Fig. 9 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 9. Dissection of the auditory region of Poiana richardsoni (AMNH 51438) in oblique lateral view (compare with fig. 7). The posterior chamber of the bulla has been opened (A), showing the inflected dorsal margin of the caudal entotympanic applied to the petrosal, and the ectotympanic resting on the promontorium anterior to the round window. Removal of the ectotympanic and rostral entotympanic (B) reveals the petrosal promontorium with ventral process produced as a flange buttressing the edge of the basioccipital. The flange is more developed in Poiana than in Prionodon, and the caudal entotympanic element is more inflated.
Fig. 1 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 1. Geographic distribution of the living Asian linsangs (Prionodon pardicolor, P. linsang) and African linsang (Poiana richardsoni), and the Eurasian localities that have produced fossils of the Oligocene aeluroid Palaeoprionodon. 1, Palaeoprionodon lamandini, Quercy fissures, France; 2, Hsanda Gol, Mongolia (?Palaeoprionodon); 3, Poiana richardsoni leightoni (western area), P. r. richardsoni (eastern area); 4, Prionodon pardicolor (northern area), Prionodon linsang (southern area).
Fig. 5 in Basicranial Anatomy of the Living Linsangs Prionodon and Poiana (Mammalia, Carnivora, Viverridae), with Comments on the Early Evolution of Aeluroid Carnivorans
Fig. 5. Basicranium and auditory region of the living African aeluroid Nandinia binotata. (A), juvenile female from Akenge, Zaire (AMNH 51450), ventral view; (B) medial view of AMNH 51450; (C) neonate, from Medje, Zaire (AMNH 51472). The ectotympanic is separated from the osseous rostral entotympanic by an intervening strip of connective tissue representing the anterior continuation of the caudal entotympanic.
