At A Glance

Researchers at Colorado State have developed a device for the purpose of drilling stable core samples and/or clean holes through stone or bone.  This device was developed to support materials research involving the structure of bone in various sizes of animal.  It has been used in several locations to drill various cores from different species of dinosaur and mammoth. Overall, the design allows the user to accommodate many different sizes and types of material to be secured and drilled, allowing a solid core to be drilled quickly, safely, and at a higher quality than typically seen in field core collection.

The device has potential use in paleontological studies that require core samples from rare and fragile fossils, as the device has proven to be safe and minimally destructive in gathering samples. Furthermore, the device is suited to boring stable holes in various types of rock – essential for geology and geotechnical engineering.

​In the fields of geology, archeology, paleontology, and other related fields, it is necessary to drill core samples of rare and fragile fossils and stones.  These bones and rocks are large, and it’s preferable to keep them where they were found.  Drilling usually occurs with a simple hand drill because it is portable and can take a core without moving the sample. However, hand drills are not very stable, drill slowly, and will sometimes rupture the sample. Keeping the sample stable while drilling strongly at odd angles is critical to obtain quality samples and minimize sample breakage.

  • Compatible with uneven sample surfaces
  • Device can be strapped to a sample at any angle
  • Allows for stable, strong, and fast coring
  • Has been used in several instances to core mammoth and dinosaur bone
  • Paleontology
  • Geology
  • Geotechnical engineering
  • Landscaping
