You got me there. To me, some papers which quote tooth "grooves or marks",
look like just preparators mistakes :-) However, here are some references
which may help you to decide on teeth marks:
W.A.S. Sarjeant (198?). Terrestrial Trace Fossils. A study of cuts,
grooves and other marks on recent and fossil bone I: Animal tooth marks.

Squaliformes) with the pinniped >Allodesmus< from the upper Miocene of
Washington. Journal of Palaeontology 68:680-84.
