The timing for the fire is estimated to be about 7.30pm (22.30 GMT) after the museum&rsquos closing hours on Sunday, September 3, and the cause of the fire is still unknown. The Brazil Museum is known as the oldest scientific institution in the country, and was known to be a repository of archeology, natural history, anthropology, and with 20 million items in its collection. This included rare objects such as fossils, dinosaur bones, a set of Egyptian mummies and a 12,000-year-old human skeleton of the oldest woman found in the Americas. There were also art and artifacts from Greco-Roman times and Egypt. The fire, however, was of such a massive scale that has reportedly charred or affected close to 90 per cent of the items in the museum.
