I got these whale bone vertebrae from a fellow who was beach combing on his 4-wheeler about a month ago after a storm. I heard he had them, so I approached him and bought them from him.
They were still oily and very smelly - I used a pressure washer and clean them up. Today, I have them on my shop south roof drying and expect they'll be there all summer. In the fall, when they are dry enough, I'll work them into my art.
