São José de Itaborai (Paleocene to of Brazil)

Also known as Companhia Nacional de Cimento Portland quarry

Where: Rio de Janeiro, Brazil (22.8° S, 42.9° W: paleocoordinates 25.7° S, 31.3° W)

• coordinate stated in text

• local area-level geographic resolution

When: Itaboraian mammal zone, Late/Upper Paleocene to Late/Upper Paleocene (58.7 - 48.6 Ma)

• Late Paleocene marl fillings in Early Paleocene karst

•Itaboraian SALMA

•Middle sequence (S2) of the Itaborai Basin sediments

•Oliveira and Goin argue that it is more likely to be late Paleocene-early Eocene in age

Environment/lithology: fissure fill; marl

• Fissure filling deposits with marls and collapsed breccias whose composition is similar to the gray limestone facies, although poorly consolidated, and transported into these cavities by heavy rains and gravitational flows

Size classes: macrofossils, mesofossils

Collected by Carlos de Paula Couto, Ney Vidal and others in 1948-1950

• Quarry under the management of the Companhia Nacional de Cimento Portland (Maui)

MCT 1791-R - type (a well-preserved small left anterior dentary fragment, broken at the level of the eleventh alveolus and bearing four fully preserved teeth); referred specimens: MCT 1792-R (small left anterior dentary fragment with no teeth); MCT 1793-R (small left anterior dentary fragment with no preserved teeth); tentatively referred specimen: MCT 1794-R (an isolated small blunt tooth [root and crown]). The specimens referred to E. itaboraiensis sp. nov. have been kept associated in the MCT collection but lack information regarding their precise provenance. However, the different colouration of these fossils and the carbonate matrix (varying from yellowish to greyish-white) suggests these specimens were recovered from different S2 fissures infills.
