More bones and bones.  The 2nd week of volunteers continues as well as every week were are out here.  Bones are found, bones are mapped and bones are excavated.  About mid-week, Burpee Expedition Veteran Joe Mongan found a beautiful tibia (lower leg bone).  It was in pristine condition.

Joe Mongin With Tibia

We are fairly certain it belongs to a sub-adult Barosaurus we have been collecting on part of the quarry we call Limb Bone Ridge.  Joe did an expert job in excavating and plastering this bone.  Interestingly, it appears that the cartilage that would have been on the top (proximal) part of the tibia had ossified while the animal was alive, meaning that this bone was done growing.  Based on the proportions of this tibia and femur found nearby, I would estimate this Barosaurus might have been 60 feet long when it died.   Considering we have front and hing limbs, hips, neck, back and tail vertebra….I am confident that we have a mountable sauropod!
