Ancient DNA in ice, such as the Ötzi the Iceman (Handt "et al." 1994), or through rapid desiccation, such as high-altitude mummies from the Andes (c.f. Pääbo 1986; Montiel "et al." 2001), as well as various sources of artificially preserved tissue (such as the chemically treated mummies of ancient Egypt). However, mummified remains are a limited resource. The majority of human aDNA studies have focused on extracting DNA from two sources that are much more common in the archaeological record – bone and teeth. Several other sources have also yielded DNA, including paleofaeces (Poinar "et al." 2001) and hair (Baker "et al."
Bükkábrány mummified forest Bükkábrány mummified forest The Bükkábrány mummified forest is a 2007 paleontological discovery in northeastern Hungary of sixteen well-preserved swamp cypress ("Taxodium") trunks of Miocene age which were found in an open pit lignite mine 60 meters underground near the town of Bükkábrány. The trunks, about six metres high and two to three metres in diameter, were cased in sand about eight million years ago, preserving their wood without fossilization. The find is unique in Europe, since trees this old have never been found in their original state and original place before. The cypresses were 30 to 40 meters high and
