NJ Big Cretaceous Bone or Ammonite with tooth marks?

Recommended Posts

Found in NJ Cretaceous stream. Thought it may be a concretion at first, and it still may be, but upon closer inspection, it appears to have tooth marks in it which makes me think it is organic in some form. Any ideas? sorry no ruler scale here, will upload later. Approximately 6 inches in length, 2 to 3 inches wide.thumbnail_IMG_3830.thumb.jpg.85d01e8bef5d9a76a8a8783f7f45b3ee.jpgthumbnail_IMG_3831.thumb.jpg.4c56794091f259811aa2d3cb96445eaf.jpgthumbnail_IMG_3829.thumb.jpg.2711ee17c82b5a2d0c43f4a402884f7b.jpgthumbnail_IMG_3828.thumb.jpg.05db5ce44b0796c31fa80fcae0ad1e99.jpgthumbnail_IMG_3827.thumb.jpg.f2862dd9f90fbd4c9c6505afe6223d32.jpgthumbnail_IMG_3826.thumb.jpg.388eb0d0e63af320371ae4261b3a9e67.jpgthumbnail_IMG_3825.thumb.jpg.8aff8c98d701a0165b75a0a708affdde.jpgthumbnail_IMG_3821.thumb.jpg.b243ea0b3b728557f693e04145cd3a9a.jpgthumbnail_IMG_3822.thumb.jpg.4cfe781b5273784545d04e810dbc0d9c.jpgthumbnail_IMG_3823.thumb.jpg.252c7b05cc1f9ef1b6c5331785369e5b.jpg

Is it possible this is a weird trace fossil of some sort? The bite marks or crustacean etchings are throwing me off on it.
