Oldest Known Arm Bone - Land/Sea Link

it is on-line if you have full sign-in authority. the free service available lets you read the abstracts of recent papers.the cover was: Good picture of the bone and location information, the "paw" may be a little imaginative. Any Idea how this compares to structure in lungfish?Introduction to the Dipnoi

thanks. I don't think they are closely related either, just that the lungfish can use their fins as rudimentary limbs. If I were going to propose a "paw" to go with the arm bone it would be more like the end of the lungfish fin: {Rescaled photo (changed UBB code to HTML) to restore page width to normal - Adminnemooseus}[This message has been edited by Adminnemooseus, 04-23-2004]

I believe lungfish can lift thier heads from muddy banks by using their fins, some better than others. I remember seeing old tv footage of some in africa, but I may be confusing them with
mudskippers (click):Lungfish have crude lungs that allow them to breath the air. Also see http://taggart.glg.msu.edu/isb200/fish.htmThere are several fish that climb out of water for various purposes. These should be compared to the bone in question to see if there are limilarities.

thanks. lots of good work there (although can't see two of your pictures).Looks like convergent evolution to me. I knew from cladistic tree that lungfish were off the tetrapod lineage, my point was only that an early foot would look more like a fin than a foot. I have also tracked my old source back and it was mudskippers and not lungfish I saw ... and that's a hoarse of a different cholera. They say as you get old that memory is the second thing to go(and I can't remember what the first was ...)

Nice pics. Still seems a little fully developed for a first effort?if you edit my post
http://EvC Forum: Oldest Known Arm Bone - Land/Sea Linkyou can copy the coding for size and quote box to make the lungfish fin more visible (hate those transparent gifs) [This message has been edited by RAZD, 04-29-2004]
