Their one-year scientific analysis found that the supposed centuries-old creature is largely a molded object consisting of paper, cloth, cotton and other components, the team said on Feb. 7. [...] They said some real biological parts were found in the mermaid. For example, the lower body contains bones from perhaps the tail and dorsal fins of a Sciaenidae fish, while the mummy's jaw was that of a carnivorous fish. But they found no major bones in the spine or rib cage. And the jaw was the only bone in the head. The body's interior consisted mainly of a mold of cloth, paper and cotton. The head was almost entirely made of cotton, along with plaster and similar materials, they said. The surface of the upper body was created with thin layers of paper, with puffer fish skin and animal hair glued to it, according to the study. Based on scales peeled from the lower body, the researchers said it is highly likely that the mermaid was created in the late 1880s.
