Caesalpinia pecorae, commonly known as the Divi Divi Tree, is a leguminous tree or large shrub whose ancient relatives thrived in the Eocene epoch. Fossil specimens from the Green River Formation, spanning Utah, Colorado, and Wyoming, date to the early Middle Eocene, approximately 53–48 million years ago. These fossils preserve leaves in fine detail, revealing delicate venation patterns that reflect the plant’s structure and ecological role.
Although the Green River Formation is best known for its exceptional fish fossils, it also preserves a diverse array of flora and fauna, including invertebrates, vertebrates such as reptiles and mammals, and even rare Eocene stromatolites. Some fossil leaves show traces of tiny insects, though these are not always well-preserved, making such associations particularly valuable for understanding Eocene ecological interactions. Insects are rarely represented in these deposits, which adds scientific significance to these fossils.
The abundance of Caesalpinia pecorae and other leguminous plants indicates that they were a prominent component of lake-margin vegetation, contributing to the lush ecosystems surrounding the large freshwater lakes of the Eocene. These fossils offer paleobotanists, educators, and collectors a tangible connection to ancient landscapes, providing insight into plant diversity, paleoecology, and the evolution of leguminous flora.
