Shark tooth I found in Missouri and possible bone?

[Samurai]

Location: Missouri

Geological map states that the area is Pennsylvanian

Found in a rock pile left by construction workers that blasted out the rock.

I have found a few teeth in the area such as Petlodus, Orodus, and a few others. Previously posted on r/FossilID  they gave some good insight,

but I am curious to what other enthusiast think. I know its some sort of Holocephalan but I was told it could be something from Eugeneodontida

I have also found another fossil near it, but i did not want to assume they were from the same shark, or if it was from a wild more modern animal

  

Size reference, with right side having flash on while the left does not.
