A couple of ossified tendons that a friend brought back from his property some time ago. A great piece here. This one has sat in my collection for a long time. Now up for sale and cheap. Both pieces are from the same animal.
Tape is to keep the one piece in place in the rear of the vertebrae.
This one has sat in box in my basement along with the tendons listed above. Trying to clear out some old stock. It was found with the rest of the pieces listed above. Track is difficult to see with the light refelecting on it. Track appears to be another juvenile.
