The bull kauri (scientific name: Agathis microstachya) is a type of conifer tree. Conifers are trees that usually have needles and cones, like pine trees. This special tree belongs to the Araucariaceae family. It only grows in Australia, which means it is endemic there.
Scientists John Frederick Bailey and Cyril Tenison White first described the bull kauri in 1918. Sadly, the bull kauri is currently threatened because its natural home is being lost.
