Miocene_Mason Posted August 17, 2017 Share Posted August 17, 2017 I wonder if this will have an impact on the validity of other lobopods... “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

At a minimum, please read the abstract. It has nothing to do with validity of other lobopods. Link to comment Share on other sites More sharing options...

Yes I read the abstract. I just remember there being debate with other lobopods over them possibly being limbs, if one was proven to be one I was wondering if others would follow. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Wrangellian Posted August 17, 2017 Share Posted August 17, 2017 What I'm seeing is the Aysheaia from Burgess is still Aysheaia, it's just the specimen(s) from the Wheeler that initially were ID'd as Aysheaia are now recognized as appendages. Interesting stuff... Goes to show how difficult this stuff can be to interpret, I guess. 1 Link to comment Share on other sites More sharing options...
