EQUINE NAVICULAR SYNDROME IN THE FOSSIL RECORD

Equine navicular syndrome (ENS) is a chronic, incurable lameness of the horse’s foot. The pathology is poorly understood but appears to be the result of mechanical stress reducing blood flow to the navicular (ankle) bone. In domestic breeds of horse the increase of mechanical stress is caused by human intervention either by increased usage such as in cutting or jumping or improper breeding practices (i.e. larger body size, with relatively smaller feet).  Mary’s research has examined fossil species of horse for the presence of this syndrome. Come hear about her research and results.Mary
