Everyday Discoveries

Why, with a collection of more than 3.5 million fossils, do we keep digging? Don't we have enough fossils? Do we really expect to find anything new?

Yes!

What Is Project 23?

In 2006, the Los Angeles County Museum of Art (LACMA) began work on a new underground parking garage. During the course of construction, 16 new fossil deposits were discovered, including the semi-articulated, largely complete skeleton of an adult mammoth. How could we get out of the way of the bulldozers but save the fossils? We built large wooden boxes around each deposit, 23 in all. The boxes were moved to their present location immediately north of the Pit 91 complex, and excavation began on "Project 23." In addition to the boxes, there were 327 buckets of fossil material recovered from the LACMA salvage site for paleontologists to clean and sort through. It's going to keep us busy for years!

Science in the Heart of L.A.

Excavation at Rancho La Brea has continued, off and on, since 1913. Many of our excavation techniques have remained the same as back then: Bones are excavated using small hand tools, field data is recorded with pen and paper, and excavators still do their own shoring.  Even our measurement system has its roots in the grid system laid out by excavators in 1913. There is some new technology, of course — electric lamps warm and soften the particularly dense asphalt of Project 23, digital cameras document day-to-day changes quickly and cheaply, and computerized databases allow us to search through collections with ease — but we doubt anything will ever replace hand tools, pen, paper, and elbow grease.

Discoveries Made Daily

We find something new every week, if not every day. Not a new species necessarily, but things like a new and uniquely laid out deposit of fossils, or new information on the geology of the deposit. Mini-discoveries like these help color our continually evolving picture of the Pleistocene in Los Angeles. Now, new species are difficult to come by, but with Project 23, we have sheer volume on our side. With the amount of fossiliferous dirt we have to dig through, we'd be surprised if we didn't discover a new type of animal. Research demands more data! Databases demand more data entry! And basic human curiosity demands that we slowly, steadily, someday reach the bottom of our inverted Everest.

That Darn CatNaegele's giant jaguar

Panthera atrox are relatively rare at Rancho La Brea in contrast to smaller carnivores such as the saber-toothed cat Smilodon fatalis and the dire wolf Canis dirus. Complete individuals of any species are also extremely rare. However, the skeleton of this Panthera atrox nicknamed “Fluffy” is relatively complete. Thus far we have uncovered approximately 40% of this animal excluding the feet. However, there still may be more yet undiscovered at our excavation site. “Fluffy” gives paleontologists new and interesting data on limb proportions of these extinct felines. Continuing research includes taphonomic studies on how the bones were found in the ground.

Tiny bones are rare in the fossil record mostly because they are too small to be seen in the field. At Rancho La Brea however, unusual skeletal elements such as this 1/8 inch ear bone called the incus are recovered in the matrix surrounding larger bones when cleaned in the Fishbowl Lab.
