You Think Your Halloween Monsters are Scary? Imagine What Your Ancestors Thought About These Terrifyingly Real Beasts...

(Modified from my post of June 8, 2011)

Happy or scary All Saint's Eve or Halloween, whatever your pleasure might be. As you cheer on the zombies and alien predators extorting candy from you, give a few thoughts about what would have been really scary: the terrifying animals that humans lived with many centuries ago.

Have you ever wondered why shadows are so effective in the best horror movies? It's pretty clear to me that there is a collective genetic memory in all of us of the monsters that we think of as myths today, but which were horribly real as recently as 12,000-13,000 years ago. The world was full of creatures that wouldn't have minded dining on us, and deep in our collective consciousness is a reflexive response to particular shapes and shadows. The pareidolia I wrote of once was a survival mechanism; we needed to see those faces in the underbrush in time to climb or flee to safety.

So who belonged to that mysterious shadow above? It was a short-faced bear, Arctodus simus, that lived in my home region, the Central Valley of California. Grizzly bears were a common presence in California when the Europeans arrived two hundred years ago. They described many of the native Californians as bearing wounds of encounters with the grizzlies, and compared to spears or arrows their guns were not much better as a defense against them. The short-faced bear was bigger, maybe 2,000 lbs or more. It may have been the largest mammalian predator ever.

There were roving packs of Dire Wolves, Canis dirus, as large or larger than their cousins in Canada or Alaska...

...and there were the Saber-tooth Cats, Smilodon fatalis, (below) along with the American Cheetah (Myracinonyx sp.)  and the Scimitar Cat (Homotherium serum). We have been living with the comforting insulation of modern civilization for a long time, but even a glance at a skeleton of these long extinct creatures can awaken nightmares in the recesses of our brains.

This museum display in Sydney gave me the willies...

If you want to see the rest of these creatures in a slightly less threatening atmosphere, check out the Fossil Discovery Center of Madera County, which opened for business a few years ago. The fossil creatures on display were found by the bulldozers of the Fairmead Waste Facility. They were digging a garbage dump, and found a treasure trove of fossil bones; 27 species of mammals and a half dozen other creatures dating from the Pleistocene. I find it to be a wonderful science resource for the region. It is well worth a visit.

Fossil Discovery Center in Madera County is Opening!

If you live anywhere near the geographical center of California, there is some exciting paleontology news! Since the early 1990's Fairmead Landfill has been the source of thousands of specimens of a diverse Pleistocene fauna, including horses, camels, mammoths, sabertooth cats, giant ground sloths and many other fascinating inhabitants of the Central Valley thousands of years ago (I've posted several items about the excavations here and here). For years the San Joaquin Valley Paleontology Foundation has been planning to develop a center where students and visitors can learn about the intriguing history of our valley. And their plans are coming to fruition.

The San Joaquin Valley Paleontology Foundation is sponsoring the Grand Opening Celebration of the Fossil Discovery Center of Madera County. The journey began in 1993 with the discovery of a seven-foot mammoth tusk. Today their expedition into a pre-historic era continues, opening the past to students, scientists and community. Come and be a part of this historical event.

A GREAT Opportunity to see some of the best of California's Geology

If you ever wanted to get out and see some of the great geological sites in California, and wished you had a knowledgeable guide and mentor to explain what you are seeing, check out this wonderful opportunity coming up on October 8-10, 2010: The Field Conference of the Far Western Section of the National Association of Geoscience Teachers, sponsored by California State University, Fresno. You don't have to be a teacher or a member to attend, and students of the earth sciences are especially encouraged to join us. Here are some of the field trips that are lined up:

Saturday Field Trips:

Topographic Evolution of the Kings River Canyon: Fluvial, glacial and Hillslope Erosion in Response to Late Cenozoic Uplift and Climate Change (Greg Stock, Park Geologist, Yosemite National Park)

Coeval mafic-felsic magmatism in the intrusive suite of Yosemite Valley (Kent Ratajeski, University of Kentucky)

Emplacement of oceanic lithosphere into the western Sierra Nevada and its welding into continental basement by batholithic emplacement (Jason and Zorka Saleeby, Cal Tech)

Growth and internal evolution of Jurassic and Cretaceous magmatic plumbing systems: an examination of the tilted Jurassic Guadalupe Igneous Complex and comparison to the Cretaceous Tuolumne Batholith (Scott Patterson, USC, and Keith Putirka, CSU Fresno)

Southern Diablo Range geology: Recorder of past subduction and current active tectonics (John Wakabayashi, CSU Fresno)

Sunday Field Trips:

Anomalous subsidence and uplift along the southwestern Sierra Nevada in relation to underlying mantle dynamics (Jason and Zorka Saleeby, Cal Tech)

Ice Age (Middle Pleistocene) Fossils at the Fairmead Landfill, a Visit to the Madera County Fossil Discovery Center (Bob Dundas, CSU Fresno)

Geology and Natural History of the McKenzie Table Mountain Preserve (Craig Poole, Fresno City College, and Chris Pluhar, CSU Fresno)

Friday and Saturday Trip:

The Other California: Mammoths and Sabertooths rise from the Prairies again!

Painting for the San Joaquin Valley Paleontology Foundation by David Douglas

Sometime back, I talked about the rich paleontological discoveries being made at the Madera County Landfill at Fairmead near the center of California's Great Valley. I mentioned the efforts to build a visitor facility, the Fossil Discovery Center, but also mentioned that I had not had the opportunity to visit the site yet. That changed today, and I am happy to report that the facility is rapidly becoming a reality. It is expected to be open for business in June.

The Fossil Discovery Center is on the corner of Road 21 1/2 and Road 19 a short distance from Highway 99, near the town of Fairmead. As can be seen, the exterior of the building is essentially complete, and when I stopped by, workers were busy putting in the high-tech connections, and working on the interior labs and classroom. I was pleased to have the opportunity to talk to Grady Billington, the President of the Board of the Directors of the San Joaquin Valley Paleontology Foundation. He kindly provided me a tour of the facility and discussed their plans for introducing valley residents to the fascinating prehistory of the region.

A full-sized mammoth skull has been hung in the central atrium. More than three dozen species of animals have been discovered at the landfill, including mammoths, mastodons, sloths, camels, horses, dire wolves, smilodon sabertooths, and short-faced bears. Skeletons of most of these animals will be part of the display when it is complete.

The original environment where the animals lived and died was a prairie with ponds and rivers flowing out of the adjacent Sierra Nevada. An outdoor pond has been constructed to recreate some of the conditions present when the Pleistocene animals were roaming the area. The hill in the background of the photo is the landfill site where the fossils were uncovered.

For more information, check out the website for the San Joaquin Valley Paleontology Foundation, or look for almost daily updates on the Fossil Discovery Center of Madera County site on Facebook.

For those who are new to Geotripper, the "Other California" is my long-running web series on the fascinating geological places in my fine state that don't usually show up on the postcards. Thanks for reading!
