Our sloth bone prototypes were a big hit at the  Gem, Mineral and Fossil Show  this passed weekend. Total attendance was  4,500.  Hundreds  stopped by the table to learn about the sloth  project and  60-70 stayed for the powerpoint talk.

Many thanks to the  Cedar Valley Rocks & Minerals Society for sponsoring the event, Steve Struckman, UI College of Engineering Prototyping Center for expediting fabrication of the prototypes, Tony Smith at the Hobby Corner for his skillful paint-job, and graduate assistant Youbing Yin, Iowa Comprehensive Lung Imaging Center for fixing the last-minute kinks in the STL files.  

The radius and ulna prototypes provoked no little amazement.  Stop by the museum for a lesson on how sloths moved their arms and to examine the other prototypes.  Sloth on!
