When these organ species are considered together as a whole plant, the study is known as a whole plant reconstruction. Some localities have enough co-occurrences of different fossil plant organs that whole plant reconstructions are possible, one example being the

As of 1986, Dr. Steven
Manchester said that "The Clarno Plane is currently the most completely documented fossil angiosperm species, known morphologically and anatomically from wood, leaves, pistillate and staminate inflorescences, fruits, and pollen." Associations of multiple organs of the Clarno
