Caesalpinia pecorae, commonly known as the Divi Divi Tree, is a leguminous tree or large shrub whose ancient relatives thrived in the Eocene ecosystems of North America. Fossil specimens of this plant are preserved in the shales of the early Middle Eocene Green River Formation, spanning Utah, Colorado, and Wyoming, approximately 53–48 million years ago.

Although the Green River Formation is best known for its exquisitely preserved fish fossils, it also contains a diverse array of plant and animal life, including invertebrates, vertebrates such as reptiles and mammals, and even Eocene stromatolites. Fossilized leaves of Caesalpinia pecorae display detailed venation, capturing delicate structural features of the plant. Occasionally, tiny insect traces are preserved alongside the leaves, although insects are rarely seen in these deposits, adding exceptional scientific value to such specimens.

The abundant preservation of Caesalpinia pecorae and other leguminous plants indicates that they formed a significant component of lake-margin vegetation during the Eocene. These fossils provide paleobotanists, educators, collectors, and museums with valuable insight into the diversity, ecology, and structure of ancient plant communities that surrounded large freshwater lakes.

Whether used for study, display, or teaching, Caesalpinia pecorae fossils offer a tangible connection to the lush Eocene landscapes of North America, illustrating the important role of leguminous trees and shrubs in prehistoric ecosystems.
