Text-fig. 3. Mandibles of (a) adult (MACN 10830) and (b) juvenile (CAV 898) specimens of Lestodon armatus. Scale bar 5 cm. in Unexpected Inhibitory Cascade In The Molariforms Of Sloths (Folivora, Xenarthra): A Case Study In Xenarthrans Honouring Gerhard Storch'S Open-Mindedness
Text-fig. 3. Mandibles of (a) adult (MACN 10830) and (b) juvenile (CAV 898) specimens of Lestodon armatus. Scale bar 5 cm.
TYPES: Male holotype from Panama: Panama: Parque Nacional Altos de Campana, 1 hectare PANCODING Inventory, 895 m, 8.68333°, -79.92972°, June 14–19, 2007, M. Arnedo, D. Dimitrov, G. Hormiga, F. Labarque, M. Ramírez, deposited in MIUP, PBI_OON 42313; same data, 1 male paratype deposited in MACN-Ar 29895, PBI_OON 42312. ETYMOLOGY: A noun in apposition; in Greek religion and mythology, Pan is the god of the wild natural world, of shepherds, flocks, and mountains, and of hunting and rustic music. He has hindquarters, legs, and horns of a goat, and the name is here employed to note the large mac- rosetae at the eye region of males that resemble the horns in some illustrations of this god. DIAGNOSIS: This is one of the most autapomor- phic species from the Americas; males have the labium fused with the sternum (fig. 34B), small chelicerae, shorter than the endite length, with anterior blunt projections, and directed backward in lateral view (fig. 34D, E); clypeus directed back- ward (fig. 34D); two light areas on the sternum just below the endites (fig. 34B), carapace almost flat in lateral view and two strong macrosetae at the eye region, pointing forward (fig. 34C–E). Other characters of the male palp, such as the presence of two apophyses, also distinguish this species from others (fig. 38D–F). MALE (PBI_OON 42312): Total length 1.00. Habitus as in figure 34A–C. CEPHALOTHO- RAX: Carapace orange, with brown stripe along in Taxonomic Revision Of The Jumping Goblin Spiders Of The Genus Orchestina Simon, 1882, In The Americas (Araneae: Oonopidae)

FIG. 15. Prothylacynus patagonicus MACN-A 5931 in Caudal Cranium Of Thylacosmilus Atrox (Mammalia, Metatheria, Sparassodonta), A South American Predaceous Sabertooth
FIG. 15. Prothylacynus patagonicus MACN-A 5931 from Corriguen-Kaik, Santa Cruz, Argentina; Santa Cruz Formation; Santacrucian, Early Miocene. Ventral view of A, the caudal cranium, with B, key. Abbreviations: AL, alisphenoid; bjs, basijugular sulcus; BO, basioccipital; BS, basisphenoid; cc, carotid canal; cod, occipital condyle; codf, condyloid foramen; cs, carotid sulcus; eam, external acoustic meatus; ewsq, squamosal epitympanic wing; EX, exoccipital; fmg, foramen magnum; fo, foramen ovale; fs, facial sulcus; hf, hypoglossal foramen; ips, inferior petrosal sinus; jf, jugular foramen; pcp, paracondylar process; PE, petrosal; pf, piriform fenestra; pgf, postglenoid foramen; ptp, posttympanic process; SQ, squamosal; tc, transverse canal. In this taxon, the more rostral foramen, opening into the basijugular sulcus, is tiny, and it presumably did not carry the hypoglossal nerve. For this reason, we identify it as a strictly venous foramen. Asterisk (*) indicates putative suture between alisphenoid and squamosal. Arrow indicates the direction to or the position of features hidden by other structures.
FIG. 14. Astrapotherium magnum MACN A 8580 in Cranial Morphology And Phylogenetic Relationships Of Trigonostylops Wortmani, An Eocene South American Native Ungulate
FIG. 14. Astrapotherium magnum MACN A 8580, transverse segments through skull in rostrocaudal order, all to same scale. In A, B, continuous chambers related to massive frontal sinus expansion serve to isolate cranial cavity from skull's sidewalls (suggested by black arrows); C, successive segments through apparent right side, illustrating relationship of frontal sinus (1) to extratympanic aditus (2) and other chambers in retroarticular process (3); D, segment through fenestra vestibuli (4) and aditus of epitympanic sinus, fully prepared on right side (white arrow) but still blocked by matrix on left; E, F, segments through rear of tympanic cavity and foramen magnum, illustrating positions of temporal sinus, posttemporal canal, sulcus for?vertebral artery, lambdoidal process of petrosal, and paracondylar process (cf. Tetramerorhinus, fig. 40H). In B, C, white asterisks mark a large longitudinal conduit within cranial sidewall that corresponds, in other SANUs, to trackway of temporal sinus. But this feature also communicates with spaces that open into retroarticular process' aditus, indicating that both kinds of sinuses (pneumatic and venous) were housed in same bony chambers (see text).
FIG. 13. Astrapotherium magnum MACN A 8580 in Cranial Morphology And Phylogenetic Relationships Of Trigonostylops Wortmani, An Eocene South American Native Ungulate
FIG. 13. Astrapotherium magnum MACN A 8580, parasagittal segments through left side of caudal cranium, sequence lateral to medial. In A, inset passes through skull just medial to the complete segment; note small epitympanic sinus and proximity of aditus of extratympanic sinus (see also fig. 27). In B, asterisk marks lambdoidal process of petrosal also seen in inset (see also fig. 14F). In C, D, curved black arrows indicate continuity between frontal sinus and air spaces throughout skull; note relatively small size of braincase. Cobbly appearance of bone and matrix in nasal region is due to artifacts in CT data. Premaxillae missing postmortem in this specimen (but see fig. 4).
