Notes: University of California at Berkeley forestry professor Paul J. Zinke and graduate student Alan G. Stangenberger discovered Dyerville Giant in 1966 and named the tree after the nearby, defunct town of Dyerville. Although Zinke and others suspected, as early as 1966, that Howard Libbey was no longer world's tallest, nobody knew that Dyerville Giant had been the new height champion until naturalists Michael W. Taylor and Ron Hildebrant estimated its height from marks made on a nearby tree when it fell on March 25, 1991. The tree was more than 10 ft (3 m) taller than a nearby sign once indicated.

Dyerville Giant (1,010 AF points) was the American Forests national champion coast redwood from 1972 until 1991. After Dyerville Giant fell, Giant Tree (1,017 AF points) became the new champion, but other trees, including Iluvatar (1,084 AF points), Terex Titan (1,087 AF points), Howland Hill Giant (1,092 AF points), El Viejo Del Norte (1,177 AF points), Bull Creek Giant (1,190 AF points), Sir Isaac Newton (1,203 AF points), ARCo Giant (1,211 AF points), Melkor (1,216 AF points), Del Norte Titan (1,222 AF points), Lost Monarch (1,290 AF points), Godwood Creek Giant (1,295 AF points), and Juggernaut (1,359 AF points) have since surpassed it.

The town of Dyerville, named after Charles Dad Venson Dyer (its oldest resident), was destroyed by successive floods in 1937 and 1955. Remnants of the town were buried during construction of Highway 101 in 1957.
