Item First records of fossil sergestid decapods and fossil brachyuran crab larvae (Arthropoda, Crustacea) : with remarks on some supposed palaemonid fossils, from the Santana Formation (Aptian-Albian, NE Brazil). American Museum novitates ; no. 3132(New York, N.Y. : American Museum of Natural History, 1995) Maisey, John G.; Carvalho, Maria da Gloria Pires de.Item Lower-Early Middle Devonian calmoniid trilobites from Mato Grasso, Brazil, and related species from Paraná. American Museum novitates ; no. 3022(New York, N.Y. : American Museum of Natural History, 1991) Carvalho, Maria da Gloria Pires de.; Edgecombe, Gregory D.Item A Middle Devonian trilobite assemblage from Venezuela. American Museum novitates ; no. 3292(New York, NY : American Museum of Natural History, 2000) Carvalho, Maria da Gloria Pires de.; Moody, John M.Item New calmoniid trilobites (Phacopina, Acastoidea) from the Devonian of Bolivia. American Museum novitates ; no. 3407(New York, NY : American Museum of Natural History, 2003) Carvalho, Maria da Gloria Pires de.; Edgecombe, Gregory D.; Smith, LeGrande.Four new taxa of Lower Devonian Calmoniidae from Bolivia are described: Gemelloides delasernai, n. gen. and sp., Eldredgeia eocryphaeus, n. sp., Wolfartaspis liebermani, n. sp., and Granadocephalus hannibali, n. gen. and sp. The new genus Gemelloides is sister taxon to Vogesina Wolfart, 1968. Eldredgeia eocryphaeus, from the Scaphiocoelia Assemblage Zone in La Paz and Tarija Departments, closes a stratigraphic gap/ghost lineage in the early history of the Metacryphaeus group. Wolfartasapis liebermani (Icla Formation, Kochis, central Bolivia) predates its only congener, W. cornutus. A novel combination of features within Calmoniidae characterizes Granadocephalus hannibali, from the Icla Formation in Cochabamba Department. This monotypic genus may have its closest relatives in the Calmonia group.Item Occurrence of Dipleura dekayi Green, 1832 (Trilobita, Homalonotidae) in the Devonian of Colombia. (American Museum novitates, no. 3902)(American Museum of Natural History., 2018-06-21) Carvalho, Maria da Gloria Pires de.A large and almost complete dorsal exoskeleton of a homalonotid trilobite from the Middle Devonian of Colombia (Floresta Formation) is described and referred to Dipleura dekayi Green, 1832, confirming prior suggestions of biogeographical affinity between Colombia and the North Eastern Americas Realm during Devonian times.Item The trilobite "Dalmanites" maecurua Clarke, 1890 (Middle Devonian, Amazon Basin, Brazil) and the new genus Amazonaspis (Synphoriidae) ; American Museum novitates, no. 3591(New York, NY : American Museum of Natural History, 2007) Carvalho, Maria da Gloria Pires de.; Fonseca, Vera Maria.The revision of "Dalmanites" maecurua Clarke, 1890, from the Upper Lontra Member, Eifelian, Maecuru Formation, Pará State, Amazon Basin, Brazil is presented. The new genus Amazonaspis is assigned within the family Synphoriidae. Comparisons are made with other Silurian and Devonian synphoriids, and some paleobiogeographic inferences are presented.
