Ok, the first photo is how a piece of rock looks when I find it. Its hard to see, but there are some bumbs in this slab of rock that tells me its a complete Phareodus. I use two different airscribes to get down close to the bone and then clean it up using an air abrasive system. I start working on the head of the fish and work down the back bone and stop once I get to where the tail starts. I always to the fins last. Some very very tiny bones make up the fins! Once I have the head and backbone mostly done, I then start taking off the rock from the dorsal side of the fish and then move underneath to the ventral side. Thats what you see in these 4 photos. I have three more to post. enjoy
