\"\"Triceratops or Tyrannosaurus rex bulling its way through a pine forest likely dislodged flowers that 100 million years later have been identified in their fossilized form as a new species of tree.<\/p>\n

Entomologist George Poinar Jr., professor emeritus in the Department of Integrative Biology, said it\u2019s the first time seven complete flowers of this age have been reported in a single study. The flowers range from 3.4 to 5 millimeters in diameter, necessitating study under a microscope.<\/p>\n

Poinar and collaborator Kenton Chambers, professor emeritus in OSU\u2019s College of Agricultural Sciences, named the discovery Tropidogyne pentaptera based on the flowers\u2019 five firm, spreading sepals; the Greek word for five is \u201cpenta,\u201d and \u201cpteron\u201d means wing.<\/p>\n

\u201cThe amber preserved the floral parts so well that they look like they were just picked from the garden,\u201d Poinar said. \u201cDinosaurs may have knocked the branches that dropped the flowers into resin deposits on the bark of an araucaria tree, which is thought to have produced the resin that fossilized into the amber. Araucaria trees are related to kauri pines found today in New Zealand and Australia, and kauri pines produce a special resin that resists weathering.\u201d<\/p>\n
