Petrified Woods of the Anza-Borrego Desert

Date: 
Monday, January 12, 2015 - 10:00am

Walnut, laurel, ash, avocado and palm trees were common a few million years ago in the Anza-Borrego desert. On January 12, Botany Society members and guests in Borrego Springs will learn about how some of these plants became petrified.

Tom Spinks, a State Park Paleontology Society volunteer who is studying the curation of fossil plant materials, will reveal how the fossils are identified in his talk about the “Petrified Woods of the Anza-Borrego Desert.” Between 2.5 and 4 million years ago, the climate was quite different from what it is today, and supported populations of birds, camels, horses, sloths, mastodons,  and other animals.  Their fossils and those of the plants are among the survivors.

The presentation will start at 10 a.m. in the Anza-Borrego Desert State Park Visitor Center at 200 Palm Canyon Drive in Borrego Springs. The public is invited, and there is no admission charge.

Spinks, a retired public service economist, has a master’s degree from the University of Minnesota Department of Agricultural and Applied Economics.
