Dino bone cutting/polishing and tooth id woodbine formation ?

[Callahan]

All, I’m starting to cut/polish some of the suspect dino/aquatic dino bones found in woodbine formation this year. 
 

most are full of pyrite/fools gold and are coated with this sulfuric deteriorating substance. 
 

once I start cutting past dusty stuff I seem to hit the pyrite or some other metallic like rock that replaced bone marrow ?  Goin through wood cutting scroll saw blades like crazy and going to get some ceramic metal saw blades. 
 

I was successful and made it through one bone so far. And included A pic. 
 

dino correct on the one I cut all the way through?  
 

here are specimens I’ve started cutting the grey pyrite one is very nasty and sulfuric and yes I’m wearing a mask now. Powder is pungent and no telling what would do to your lungs. 
 

also here is a tooth I beleive that’s not shark but from some creature from the woodbine 

 

it’s broke but here is some pics. Possibly this tooth is from the creature the bones come from and the vertebrae I found in the past at the site. 
 

any recommendations in cutting bones and tooth id would be much appreciated. 
 

tooth looks nothing like the few shark teeth I found at site. 
 

ps I found several of these claw looking things I glued back together.  Are they anything bone/very deteriorated teeth/claws or just worm calcified borrows. 
 

very fragile and have selenite encrusted on most of em. 
 

Have very little knowledge on dino bones etc and don’t look for em just came to this spot looking for Indian stuff and selenite gypsum crystals. 
 

fyi cutting and polishing possible bones for a custom knife I’m making and jewelry for daughter and wife.

The wrinkled “tooth” could be the root of a sawfish rostral tooth. I can see what appears to be enamel at the bottom where the crown of the tooth should begin. Not sure what species are known from the Woodbine, so maybe someone else can help there.

Thanks. Yeah. I have found saw fish teeth there. I will compare the full ones I have.
