Waurika Permian Fossil or not?

[gdsfossil]

Going through Permian matrix.  We have found many teeth and other identifiable microfossils.  I have also found many of these metallic looking dark rocks.  Are they bone fragments, or partially melted rocks? Thank you.

My best guess is that they are neither. They look like pedogenic iron oxides such as hematite, goethite, and  maghemite.
