224 SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY SAO PAULO STATE 220 30'S Taubate Tropic of Capricorn*^ _ jjn Sao Paulo Taubate Basin Ocean Rio de Janeiro FIGURE 1.—Map of Taubate basin showing the town of Tremembe, the type locality of Chaunoides antiquus, n. gen. n. sp.
NUMBER 89 FIGURE 3.—Chaunoides antiquus, n. gen. n. sp., holotype, left coracoid (MNRJ 4619-V), coated with ammonium chloride: A, ventral view; B, dorsal view. (Scale bar= 1 cm.) a large pneumatic foramen in the sterno-coracoidal fossa, a large procoracoid foramen, and a large transverse procoracoid process. The coracoid differs from that of Anhima by having a (1) narrower head; (2) glenoid facet with the transverse width Measurement Coracoid midshaft width acrocoracoid apex to internal angle Femur top of head to internal condyle least width midshaft Radius greatest width, distal end Tarsometatarsus width of proximal articular surface Tibiotarsus width immediately above tendinal bridge Ulna greatest width of external condyle 225 greater than the length, also easily observed in ventral view (Figures 3A, 5) because of its lateral expansion (similar to Chauna); (3) larger and deeper scapular facet; and (4) larger pneumatic foramen, with rounded borders, in the sterno-coracoidal fossa. The coracoid differs from that of Chauna torquata and C. chavaria by having (1) a smaller acrocoracoid process; (2) the scapular facet more rounded and deeper; (3) the dorsal surface less swollen; and (4) the large pneumatic foramen in the sterno-coracoidal fossa wider and dorsoventrally more compressed, with a small process in the dorsal border. Chaunoides antiquus, new species HOLOTYPE.—Nearly complete left coracoid, lacking only the tip of the head, tip of the procoracoid process, and the sternocoracoidal process (Figure 3). Vertebrate paleontology collections of Museu Nacional de Historia Natural da Universidade Federal do Rio de Janeiro, MNRJ 4619-V. TYPE LOCALITY.—Santa Fe Farm, 2 km north of Tremembe, Sao Paulo State, Brazil (22°30'S, 45°32'W) (Figure 1). Montmorillonitic clay, about 4 m below the most superficial level of shales. HORIZON AND AGE.—Tremembe Formation, Taubate basin, upper Oligocene or lower Miocene. MEASUREMENTS OF HOLOTYPE.—See Table 1. PARATYPES.—Another left coracoid lacking the sternal end (MNRJ 4620-V), identical in morphology to the holotype, associated with an almost complete left femur (MNRJ 4621-V); the distal end of a left ulna (MNRJ 4622-V); the distal end of a right radius (MNRJ 4623-V); a left radius lacking the proximal end (MNRJ 4624-V); a left ulna lacking the proximal end (MNRJ 4632-V), associated with a segment of distal shaft of a left tibiotarsus (MNRJ 4631-V); and two segments of the distal end of left tibiotarsi (MNRJ 4625-V, MNRJ 4629-V), the last being associated with the proximal end of a left tarsometatarsus TABLE 1.—Measurements (mm) of Chaunoides antiquus, n. gen. n. sp., compared with other Anhimidae.
