Prototaxites, a giant, prehistoric fossil, originally thought to be a conifer [when it was first collected in 1843], is uncovered in Saudi Arabia in an undated photo. A chemical analysis has shown that the 20-foot-tall organism with a tree-like trunk was a fungus that became extinct more than 350 million years ago, according to a study appearing in the May issue of the journal Geology.
