Calima goldsmiths achieved their foremost accomplishments during the period called Yotoco. The richly varied works made during this time are primarily objects of personal adornment, which probably functioned as ceremonial regalia for elite men: headdress elements, pectorals, bracelets, anklets, anchor-shaped nose ornaments with circular and rectangular dangles, and ear ornaments of circular, biconical, and bowl-shaped forms. Worn together, as many undoubtedly were, they would have created a dazzling, golden image.Among Yotoco gold ornaments, the pectoral and the headdress element, often called a diadem, are the largest and, iconographically, the most complex. The complicated yet symmetrical silhouette of the Dallas headdress ornament depicts multiple human and animal faces. Rectangular half-round dangles emphasize the crest and lower jaw of two crocodiles. Projecting from the lower center is a sculptural human head adorned with miniature versions of typical Yotoco gold pieces, an H-shaped nose ornament (itself a face), and two dish-shaped ear ornaments. The ornament could have been attached to a cloth headdress, possibly turban like in form, by means of the four holes beside the raised head. The pendant elements would have responded to the wearer's movements, reflecting light and producing gentle metallic sounds.Dallas Museum of Art: A Guide to the Collection, page 179
