Pristine Giant Angustidens Shark Tooth

This is it! This is the tooth I've been looking for all year long! its a massive upper principal angustidens tooth with a serious attitude from the Edisto river in fantastic condition. It measures 3 31/32 inches along the longest diagonal, just a hair below the magic 4 inch number, but I'm not complaining.

The blade is killer. Both fragile yet menacing side cusplets are intact, serrated all the way around. The blade is free of chips all the way around with every serration intact including the all important tip.

The whole bourlette is there and much of it is a light orange color that is a stark contrast to the jet black enamel and root. like a drug commercial, if i'm going to sing the praises, I also have to admit the flaws. I can really only thing of one, the root, which has some pitting on the flat side.

When it came out of the river, it was completely encrusted with algae and black river crust. I have had trouble removing that stuff in the past, but no more. I bought a blast cabinet and an air eraser that works with my compresser to remove that coating. i tested the blast media on a lesser tooth to get the hang of it before I used it on this beauty, but it works. I included pictures so you can get the idea.

After the air abrasion, I lightly buffed the enamel to remove any remaining blast media. speaking of blast media, i used aluminum oxide on this tooth but its better to use glass beads. I had to hold the air eraser a few inches further from the tooth while blasting to avoid etching the tooth.

This is the blast cabinet. Those two holes in the front are where I put my arms. There are gloves on the inside to hold the air eraser and position the fossil.
This is the air eraser. It is shaped like a pen and has a button on top that i press to blast. the black acorn looking thing is the reservoir where i put the blast media.
