on the other hand I have seen fish with claws

And now I need to take a closer look at a small trackway that I brought home, after I might add watching a greater portion erode out of a cliff face and disapear into the surf over a few years, not that there is any shortage of animal fossils and other things like fossilised rain and wave impressions, literaly 1000's of km³. As to the information that can be extracted from a trackway, it would be intetesting to run these past indiginous trackers and have them consult with scientists to train field workers doing palentological research, a realy realy cold trail.

>Except Sharks

My favorite shark fact is that they pre-date trees.
