• Agathis

  kauri, dammar

  Agathis is a genus of evergreen coniferous trees comprising approximately 22 species, commonly known as kauri or dammar. The genus belongs to the ancient family Araucariaceae, which was widespread during the Jurassic period but is now largely restricted to the Southern Hemisphere. Agathis species are characterized by large trunks with minimal lower branching, broad leathery leaves, and commercially valuable timber and resins. The genus is most diverse in Malesia and Australasia, with some species reaching substantial sizes and great age.

  snow scorpionflies

  Caurinus is a genus of snow scorpionflies in the family Boreidae, containing two described species: Caurinus dectes from Washington and Oregon, and Caurinus tlagu from Alaska. These tiny, flea-like insects are among the most unusual members of Mecoptera, with a fossil lineage dating back over 145 million years to the Jurassic. They are non-parasitic and feed on leafy liverworts in coastal forest habitats.
