Wolf Wall – George C. Page Museum

Wednesday, June 5  –  Trapped in Tar

For the last 45,000 years, the La Brea Tar Pits have captured all creatures wandering into the tar.  The tar is now revealing the history of the animals and plants living in the Los Angeles area during the late Pleistocene epoch.

Geologist John Cook will be discussing his experience extracting bone from Pit #91 while in college, bones unearthed of creatures long gone, geology, paleo environments, history, mass extinction and new discoveries at the La Brea Tar Pits.

The public is welcome to join us at 7:30 p.m. for this free  presentation.

The History of Asteroids, Written in Stone
Time: 2:30 p.m.
Location: Geology 3656

Lecture by Dr. David (“Duck”) Mittlefehldt

Dr. David (“Duck”) Mittlefehldt, Johnson Spacecraft Center in Houston s our former student. He has played important roles on several recent spacecraft studies, including the Dawn missions to the Vesta and Ceres asteroids.

Achondrites – a subset of stony meteorites – were formed by processes familiar to any terrestrial geologist: melting to form magmas, separation from their sources, and crystallization upon cooling. There are a number of achondrite groups; each from a different asteroid; each with its own story to tell of the geology of its parent asteroid. In this talk, he will discuss the mineralogy, texture, and chemistry of several achondrite groups, and describe how they inform us of the earliest phases of the geologic history of asteroids.

Death Valley National Park Fossil Thieves

$1,000 Reward – Death Valley National Park

Fossil Thieves stole several fossilized footprints, which had been left in a lakebed by mammals and birds, were missing. Now, Ryan F. Mandelbaum reports for Gizmodo, the National Park Service is asking for the public’s help in identifying a group of backpackers who may have information on the ancient tracks.  In a statement, the National Park Service released the photos of three men who might have witnessed the crime or have knowledge about the disappearance of the footprints. Investigators are offering an award of up to $1000 “for information leading to the identification, arrest, and conviction of those responsible,” the statement reads. According to Mandelbaum, investigators are planning to interview visitors who frequented the Park at the time of theft, in the hopes that someone will be able to provide valuable clues.

Destroying—or pilfering—the property of national parks is prohibited by law. “It’s illegal to collect fossils, rocks, or anything else in National Parks,” Park Superintendent Mike Reynolds said in a statement about the fossil thefts. “The purpose of National Parks is to conserve the landscape and everything it contains for the next generation. I ask that visitors come and enjoy all there is to see, and to leave it unimpaired for others to enjoy.”

The National Park Service has asked anyone with information about the stolen fossils to call the Investigative Services Branch at 1-888-653-0009.
