Burgess Shale revisions - current state?
Hello all, from a lurker:
This may not fit exactly in this list's area of expertise, but I'd
appreciate it if anyone could help. I'm writing a piece about the current
status of the Burgess Shale taxa, focussing on how Gould's theory about
decreasing disparity has held up since he published Wonderful Life five
years ago. I've seen an article in Discover from May 1992, but have found
nothing more recent. I know that Hallucigenia has been placed in the
onychophora, and that Wiwaxia and Opabinia might also belong to extant
phyla. But what are the halkieriids that Conway Morris and Peel dug up in
Greenland? How do they fit? What's the general consensus amongst
paleontologists about all this?
