This is an incredibly rare and really exceptional glyptodon tibia. This specimen is in excellent condition with super crisp features all around. Very attractive glossy blonde patina. Beyond rare to find in this nice of condition. This is the first glyptodon limb bone that we have ever offered for sale. World class example. We originally thought this was a Megalonyx sloth tibia, but it has been confirmed as glyptodon by Dr. Richard Hulbert.
