Itaboravis

Itaboravis is an extinct genus of land birds uncovered from the Early Eocene Itaboraí Formation of São José do Itaboraí, Rio de Janeiro state, Brazil.^[1][2] Based on analysis of a coracoid and two humeri it was tentatively assigned to Cariamae (=Cariamiformes), due to similarities with Elaphrocnemus, but some morphological similarities of the humerus to the palaeognathous family Tinamidae were also noted.^[2]
