Acanthodes_BW.jpg (800 × 303 pixels, file size: 17 KB, MIME type: image/jpeg)

This paleontological restoration is inaccurate, or its accuracy is disputed.

Reason: "pelvic" spine (actually unpaired) is placed too backward, tail fin too pointed.[1]

You may ask further questions about the accuracy of this image at the image review page of Wikiproject Palaeontology on the English Wikipedia. Note that this image may be appropriate to illustrate obsolete paleontological views.
