Tiny Cretaceous bone for ID

[izak_]

Any suggestions on this tiny bone? I found it while dissolving chunks of matrix from the lower Cretaceous Mackunda Formation collected in western Queensland, Australia. The matrix is rich in shells, crustaceans, fish and shark teeth but terrestrial species are known from the formation. It doesn't look like any of the fish bones I've seen from here so am considering bird? They've been found in the neighbouring Toolebuc Formation by @Mike from North Queensland so it seems possible! 

 

 

Thanks for any input:)

reminds me to a fin-spine of a bony fish

Look to be a good possibility of bird but need a photo of broken end and need to compare to other specimens
