We don't half pick the right weeks to go for weather! ;D Glorious sunshine, clouds of butterflies, and fossils everywhere. The fossils, though, were a little on the disappointing side in some ways. We had two days when we found almost nothing of great interest, but at least we've more or less got the fossil and sediment sequence at our new quarry worked out. We've also had nothing so spectacular as the trilobite "stomach" and no complete unmineralised arthropods. We did find more worms, though. About ten of them, I think - will check exactly how many once we've unpacked. They're all fragments of cuticle, but some of them seem to be gorgeous, and up to a centimentre or so in size. SEM will tell how good they really are... Also had another day at an old favourite site or ours that has produced superb carpoids... and got more of them. More of the same, and at least one (and probably parts of two more) new species. We also had a couple of sponges including possible examples of the Burgess/Chengjiang genus Leptomitus... which would be nice. Oh, and Lucy found an Ordovician feather. More of that later. Will be back with photos in a bit... Joe

Wow... I know this is an old thread but did Lucy find an armored worm / bristle worm (in reference to ordovician feather)? Any pictures to post? I love seeing fossilized worms.... soft grubby tissue preservation.

[img src=" farm3.static.flickr.com/2666/3942555894_2a4892fc18.jpg"] Ordovician feather! ;-) by joe with a camera, on Flickr[/img] This is the beastie! It's a cuticle fragment rather than a complete worm of any description. The plates being phosphatic, they do tend to stand half a chance of being preserved, despite the size. The problem is, of course, that they're held together by mostly organic stuff, which does rot away... so to guarantee finding the bits you really want to dissolve limestones and use a very fine mesh!
