  :Hi Graham.  Thanks for your efforts on this.  Your text is so much better than what was there before.  I originally intended to tackle the page myself, but it's really not my area, and I'd probably have wound up just tweaking what was already there.  It was something of a relief when I saw that you'd already written an alternative on the talk page.  Anyway, I've just had a go tweaking the paragraphing of the text and wikilinking (you know, the hard bits!).  I'll have a read through at some point and see if I can expand it anywhere (unlikely).  One thing I note the page could do with is some figures.  There are a few animals linked in the article, but only ones like Hallucigenia have anything approaching an image we could use here.  If you've any appropriate images yourself (especially if they've been used in papers that could be cited), I think they'd help illustrate the topic.  Cheers,
