Alvarenga (2007b) determined as Anodorhynchus glaucus or Anodorhynchus leari an almost complete maxilla (MNRJ-A-LV-81) from Lapa Vermelha IV in Confins, Minas Gerais, in sediments dated about 9,000 years BP. It was discovered by the Franco-Brazilian Archeological Mission (1971–1976) and briefly mentioned and depicted by Souza Cunha and Guimarães (1978, 1981 –1982). A tarsometatarsus of a large bird and mammalian remains (especially rodents and marsupials) were found in the same sediments.

The identical size and shape of the specimen compared with A. glaucus or A. leari and the fact it was found between the historically known range of these two species prevent a more asserting determination. However, Alvarenga found it is quite unlikely it represents a still-unknown species, despite an earlier mention as such in Yamashita (1997). Based on the data obtained from the remains found in Bahia (see below) and Minas Gerais, and by comparing the skins and skeletons of these two species, Alvarenga reinforced the interpretation that they represent geographic races or subspecies, suggesting a contiguous geographic distribution and clinal variation of the plumage dating at least 10,000 years.

594. Anodorhynchus leari Bonaparte

Late Pleistocene – BA

Anodorhynchus leari – Alvarenga 2007b: 427–432, figs 4–7.

In addition to the material from Minas Gerais, Alvarenga (2007b) associated with this species (based on its geographical origin) bones collected by the Cástor Cartelle at Gruta dos Brejões in Morro do Chapéu, Bahia, dated about 12,200 years BP .

The material consists of an incomplete mandible (MCL A 821) and complete and well-preserved post-cranial bones, which possibly belong to a single young individual: a right coracoid (MCL A 1693), a left coracoid (MCL A 1709), a left tibiotarsus (MCL A 1707), and a right tarsometatarsus (MCL A 1769).
