Two bones with the same shape

[D.N.FossilmanLithuania]

Dear Guys,

 

I recently found two small scapula- like bones in flintstone erratics of Varena town, South Lithuania that are dated by Late Cretaceous- Paleocene age, the both are the same in shape and features so I think they are from the same narrow taxon but it is difficult to me to identify. Please ehlp with ID.

 

Best Regards

Looks like a cross section view. I doubt they are identifiable.
