Inscription.  

This family circle of fossilized stumps grew out of the single trunk of an older parent tree. The three trunks are ancient clones, or genetically identical copies, of that parent tree.

Modern coastal redwoods also reproduce by stump sprouting. If a redwood is toppled or burned, a ring of new trees often sprouts from burls around the trunk's base. In the coastal redwood forests, family groups are common. But this trio of stone stump is unique in the world's fossil record.

If the main trunk of a redwood is damaged, the dormant stems begin growing rapidly, using the parent tree's root system for nourishment and support.

Harry D. MacGinitie, shown standing by a modern redwood trio in California, was a paleobotanist who excavated fossils at Florissant during the Great Depression years of 1936 and 1937.

His work, published in 1953, is still the most comprehensive study on Florissant's fossil plants. MacGinitie was the first to compare these fossils with modern vegetation in order to reconstruct past climate, ecology, and elevation.
