A GEM, Hybodus dorsal spine - extra large size!Exceptionally articulated and preserved. Incredibly complete without repair. Note strong longitudinal grooves on the sides. Museum Quality
These are excellent and HUGE examples of extinct Hybodus dorsal spine. Cretaceous age. Superb quality specimens - extra large and excellent preservation. Do not see these very often! These are the best quality Hybodus spines that I have seen - incredible specimens!
