"I haven't really dug into this particular find. But just looking at the picture, it doesn't look very fish-like to me. It looks more like a crocodile...as does an alligator...yet this is a different creature as well. But how can one tell just by looking at this creature's head?"
Everyone has an opinion. I tend to value those who have devoted their life's work to a paticular study above someone who glances at a photo though.
