Series: Geologic Time Periods in the Paleozoic Era During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era. fossil corals in a rock matrix Ordovician Period—485.4 to 443.8 MYA Shenandoah and Great Smoky Mountains national parks, along with the Blue Ridge Parkway that connects them, pass through rocks from the core of the Appalachian Mountains.

These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios. Green, orange, and dead grey junipers in red soil, mountains in background Helping a New National Monument: Katahdin Woods and Waters On the eve of the National Park Service’s centennial in 2016, President Barack Obama designated 87,500 acres as the Katahdin Woods and Waters National Monument – the first national monument to preserve the landscape and honor the history and culture of Maine’s North Woods in Penobscot County. The superintendent of the new national monument asked NPS-RTCA to assist with engaging local communities and leading various planning projects.

Fossils have been occasionally reported from the monument by scientists in the past, but this is the first time that a thorough inventory has been made of the monument’s fossils.
