Dirt Screening Plants Can Sift Out the Bones
By Conus on Jul 24, 2008 in Society
Imagine arriving on site to a dig, which could be unearthing a huge discovery in paleontology. Fossilized bones are scattered in the dirt, but without a sophisticated machine to help, workers have to sift through the ground material with handheld screeners. This takes too much time, and the people doing the work get tired. These aren’t the biggest bones ever found; some of them are even quite small, but to continue the work, a couple of rock screens are brought in. The bones are somewhat larger than the surround dirt and gravel, so they are separated from the rest of the unneeded material, which gets filtered out.
With the workload accomplished by dirt screening plants, the project is completed sooner and a new prehistoric species is identified. Seeing its skeleton in the museum, most people wouldn’t realize the work and the machines that were used in excavating it. From the dry, barren ground that was once a moist haven for prehistoric life; the ancient bones have been unearthed by a convenient invention in modern technology. This is just another example of how a Topsoil Screen can positively affect the way things are done.
