Hi Alwayslearning,
Just saw your post here...Is this in "What is it" forum?...Or Todays Finds?...might get more reponses in those forums...That Said...I have several variations of your 1st pic...It is called a "Hook scraper"?..I will check the name for sure but when it has a "Hook" such as yours it is an artifact...just need to research the age and purpose of that one...Sorry I can't be more definitive on this one...The bone pics, really not a "bone" person...but the hole in it is really strange..ha possibly hung around the neck?
Hope you get more ideas from those who know more...MinerGirl
