Laguna Trailhead
- Type: Place
The most popular hikes from the Laguna Trailhead will take you down to the coast, but you can also connect to multiple trails that will climb through the forest towards Inverness Ridge. Many of the routes that depart from this trailhead are within the Phillip Burton Wilderness. The trailhead is located near the east end of Laguna Road, approximately 15 minutes by car from the Bear Valley Visitor Center.

This biannual newsletter of the Mojave Desert Network Inventory and Monitoring Program features: a summary of the network's 4th science symposium; a farewell article by departing vegetation field lead Joe Ladd; recent publication of a Streams and Lakes Monitoring hydrologic and benthic invertebrate data package; staffing updates and field sampling schedule; and continued outreach to parks to assist in increasing science and research content on their websites.
- Type: Article
National parks contain a rich diversity of invertebrate fossils. Some groups, particularly mollusks, are present in many national parks, but others are much more rare. Most invertebrate fossils in national parks are of marine organisms, although some parks have freshwater mollusks, and a few have fossils of terrestrial arthropods, mostly insects.

Fossil Graptolites
- Type: Article
Graptolites are important index fossils for the early Paleozoic. They look like pencil marks on rock faces but are the remains of tiny colonial animals. Graptolite fossils are known from a handful of national parks.

Fossil Cnidarians - Corals, Jellyfish, and Sea Anemones
- Type: Article
Fossils of bryozoans (“moss animals”) that are typically found as part of marine assemblages in many national parks. These filter-feeding colonial animals were individually microscopic so even their colonies, usually shaped like branching twigs or net-like and lacy forms, themselves are quite small.

Fossil Mollusks
- Type: Article
Most mollusks are of either bivalves, cephalopods, or gastropods. Cephalopods including nautiloids and ammonites were exclusively marine, bivalves inhabited both marine and freshwater environments, and gastropods lived in both aquatic and terrestrial environment. Overall, mollusks are the most common type of fossils found in national parks.

Fossil Echinoderms – Crinoids, Blastoids, and Others
- Type: Article
Crinoids are the most common echinoderm fossils in national parks, found mostly in Paleozoic rocks. Echinoderms have 5-sided symmetry and have skeletons composed of numerous small pieces, which break apart after death. Thus, most echinoderm fossils are only small bits of the larger organism.

Fossil Brachiopods
- Type: Article
Brachiopods are one of the most common marine invertebrate fossils found in Paleozoic rocks in national parks. They were a dominant group of marine organisms during the Paleozoic, filling many of the ecological niches in Paleozoic oceans that bivalves have occupied since the end of Permian extinction, when most brachiopods became extinct.

Fossil Sponges
- Type: Article
Sponges (phylum Porifera) are simple animals with a fossil record dating back to the Precambrian. Only sponges with hard parts (such as spicules) are capable of being fossilized. Sponges were important reef builders in the Paleozoic and most sponge fossils that have been documented in national parks are in Paleozoic rocks.

Fossil Arthropods - Trilobites, Insects and Spiders, and Others
- Type: Article
Arthropods have segmented bodies and external skeletons. Trilobites and ostracodes are the most common marine arthropod fossils in national parks. Fossils of insect and spiders are quite rare in parks except at Florissant Fossil Beds National Monument where fine-grained shales provided the perfect conditions to preserve the remains of these delicate organism.

Bayview Trailhead
- Type: Place
Multiple trail options begin at the Bayview Trailhead, leading either down to the coast, along the Inverness Ridge, or through the Phillip Burton Wilderness. The Vision Fire burned through this area in October 1995. The trailhead is located along Limantour Road, approximately 10 minutes by car from the Bear Valley Visitor Center.
Anacostia Park
Aquatic Resources Center
- Type: Place
Aquatic Resources Education Center is the host to 20-1,500-gallon aquariums where visitors can have insight of what's beneath the waves of the Anacostia and to learn about the variety of aquatic life that is supported by the river. Well over 40 species of fish, amphibians, reptiles, and invertebrates from the District and the Chesapeake Bay are on display at the facility. The AREC is a multi-use environmental education center located in Anacostia Park, SE run by DOEE.

Sky Trailhead
- Type: Place
From the Sky trail, many routes and loops are available leading into the Phillip Burton Wilderness along the spine of Inverness Ridge, downhill to the coast, or downhill to the Bear Valley area. The habitat changes from forest to coastal scrub and mixed woodland depending on your route. The trailhead is located along Limantour Road, approximately 10 minutes by car from the Bear Valley Visitor Center.

John Boyd Thacher State Park National Natural Landmark in eastern New York is one of the newest NNLs. It is notable for its extensive middle Paleozoic stratigraphic section and the many invertebrate fossils found in the rocks, both of which have been studied since the early 19th century, making it a noteworthy scientific and historic site.

Big Bend National Park preserves an important fossil record spanning the Cretaceous / Paleogene boundary. Both marine and terrestrial strata preserve a diversity of vertebrates, invertebrates, plants and trace fossils. A recent inventory of NPS fossil plants from across the national parks includes the important fossil record of flora from Big Bend National Park.
