Jonathan Wingerath is a Museum Specialist who manages the Paleobotanical collections at the Smithsonian National Museum of Natural History. He grew up in northern New York State and became interested in paleontology as a Geology major at St. Lawrence University. During vacations he explored the fossil bearing outcrops of local Ordovician limestones, finding an occasional trilobite, brachiopod, or crinoid fragment. At Yale, he received his master’s degree in Forest Soils and Hydrology. Between the summers of 1988 and 1989 he was employed by the State of New York to map large sections of the surficial geology in the St. Lawrence Lowlands. He also worked as a Peace Corps volunteer in the Department of Concepcion, Paraguay, teaching agroforestry practices to farmers, public school teachers and their students. Wingerath began his career at the Smithsonian in the Division of Sedimentology, applying his knowledge of geology, soils, and hydrology to projects involving the Nile River, Nile delta, and offshore sedimentation in the Levant region. His current work involves organizing and housing approximately 6.5 million fossil plant specimens, facilitating the work of paleobotanists at the Smithsonian and scientists from all over the world. He also prepares thin-sections of paleontological, biological, and geological materials.

About Plants (Kingdom Plantae): Paleobiology

Plants on Earth began life in the water. The earliest plants were aquatic algae, living in the warm seas more than 500 million years ago. By the Silurian and possibly the latest Ordovician (as much as 440 million years ago), plant life on land had begun. While terrestrial plants had more access to sunlight, challenges included supporting their weight and distributing water throughout their tissues. During the Devonian explosion (55 million years, which is brief in geologic time), plants evolved from small, simple forms to a huge variety of larger, complex forms adapted to life on land. Club mosses, horsetails, ferns, and probably sphenopsids originated. The incredible seed, which safely packages the developing plant embryo, also evolved. Plants extended their reach underground with root systems, providing the anchor and water supply to support large trees. Although plants were to undergo many changes over time, by the end of the Devonian (the golden age of plant evolution), the groundwork had been laid for the terrestrial ecosystems of today.
