The giant tree, whose top juts out high above the canopy in the Iratapuru River Nature Reserve in northern Brazil, is an angelim vermelho (scientific name: Dinizia excelsa) measuring 88.5 meters (290 feet) tall and 9.9 meters (32 feet) around -- the biggest ever identified in the Amazon, scientists say.
