National Fossil Day

The Oxnard Gem & Mineral Society is an official National Fossil Day Partner.

A Shasta Ground Sloth, Nothrotheriops shastensis, is entering the entrance of Rampart Cave 11,000 years ago. The cave and the ground is carpeted with its large droppings. A vampire bat, Desmodus stocki, roosts in the cave ceiling while it awaits for nighttime to forage for food. The 2019 logo artwork honors the 100th anniversary of the establishment of the Grand Canyon National Park, which occurred on February 26th, 1919 by President Woodrow Wilson.

badgeThe National Park Service and the American Geological Institute are partnering to host the annual National Fossil DayTM on October 16, 2019 during Earth Science Week.

National Fossil DayTM is a celebration organized to promote public awareness and stewardship of fossils, as well as to foster a greater appreciation of their scientific and educational value.

Ventura County is home to a wide range of fossils

Columbian Mammoth?

In September 2016, it was announced that the skull and tusks of “Larry” was discovered on Santa Rosa Island.  The find appears to be a young Columbian Mammoth.  Further research will be needed to confirm if it is a Pgmy, Columbian or something in between.  The nickname honors the discoverer, Peter Larramendy, and leading mammoth expert Larry Agenbroad.

Pygmy Mammoth

The most complete Pygmy Mammoth ever found, was discovered in 1994, on Santa Rosa Island.  A replica can be seen for free at the Channel Islands National Park Visitors Center.

“Emma” The Moorpark Mammoth

In April 2005, a Southern Mammoth fossil was discovered in Moorpark during the construction of new homes.  In the same location, parts of a Columbian Mammoth, Western horse, a large-headed llama, a rabbit, a kangaroo rat and other rodent ancestors were discovered.  A Mammoth Sculpture for Kids to Play on is a feature of the Mammoth Highlands Park in Moorpark.
