Fossil Point is a prominent landmark in Lake Clark National Park and Preserve on the south shore of Tuxedni Bay, at the north end of Tuxedni Channel and west of Chisik Island, about 56 miles (90 km) southwest of Kenai, Alaska. The local name was first published in 1912 by U.S. Coast and Geodetic Survey.

The western coast of Cook Inlet is made of marine sedimentary rocks that contains fossils spanning the geologic record from the Permian (~260 million years ago) to the Cretaceous (~70 million years ago). These rocks were formed offshore of the paleo-Alaskan coast and have one of the most complete and best-preserved Jurassic (145-201 million years ago) sedimentary rock sections in the world. Fossil Point is important because it contains one of the most productive marine invertebrate fossil sites known in Alaska. The Middle Jurassic Tuxedni Group contains exceptionally rich and diverse mega-invertebrate fauna including ammonites, bivalves, and other invertebrates.

The rock strata exposed at Fossil Point have been known for their extremely prolific fossil invertebrate marine fauna since the final days of Russian America. A significant fossil collection was made by the Russian mining engineer Peter Doroschin and sent to the Russian capital at Saint Petersburg where they were ultimately studied and described by Eduard von Eichwald (1795–1876), one of Russia’s early and preeminent paleontologists. Fossil Point has also long been known to Cook Inlet fishermen and extensive fossil collecting has taken place by private fossil collectors. Fossil specimens from Fossil Point are on display in many businesses and homes in the cities of Homer and Anchorage. Read more here and here.
