All about the same size,and maybe all marine.

 

 

A tip or a root.  See the following thread for clues... maybe

 

A bone.

Dave,

Thanks for the response!!!  It moved me a little further.

 

Seal would be extremely rare in my hunting area.  Most likely a river dolphin:

On the 3rd,  Turtle flipper bone is difficult to find a match.  Humerus, Radius, Ulna ???

 

On the middle one,

My first impression was walrus tusk,  but it is so small, even as a tip.  Thinking of a more common mammal, It thought it might be the broken tip of a mammoth tooth root. The broken enamel resembles mammoth, but never have I seen the crenelations like those on the outside of the enamel.

Lastly , I have been considering sirenians... possibly Metaxytherium floridanum.

Some additional photos. Cementum on one side,  enamel, and then what is that inner core material....

Dave,  I agree that your bone and my bone are the same,  Just working on the proper search technique to find another that is isolated and named. The bone circled in blue is Carpal #5 (I think)
