Urggh... I can't see anything that suggests specifically lobopod, Peter... but like a lot of these things, the problem is the preservation is very faint. There doesn't seem to be any difference in the surface texture/composition to the surrounding rock. It's also parallel with those strande or streaks going across the surface which look horribly like scratches. Can you honestly rule out it being an artefact?
If (and it's a very big IF) that's a fossil, preserved as a mould of some organism, then you would have to look at a whole stack of different things, such as polychaetes, pennatulaceans, algae, hydroids and bryozoans... and there really doesn't seem to be the detail in the object to tell them apart, I'm afraid. It's one of those things where it might make sense if you find another one which is better... but honestly, my hunch is that it's not a fossil.

Thanks for the analysis Joe, ... oh well  Reimaged using full spectrum camera... wb corrected... it is distint from matrix think it could be a crinoid .... see star crossection towards far right...  |

Shame - I do hope I'm wrong when it's a verdict like that...  |

Thanks Steve... visited the Bertie Lagerstatte April 11... found a clump late Silurian plant View AttachmentThat's a nice one... alga, presumably? I don't see any Cooksonia-like features there. |

Yes Joe: It is a alga in nature.... found it in a waste pile ... someone found it and threw it out and I picked it up the Bertie Lagerstatte is almost mined out.... there is an area about 60 ft radius x1.5 ft deep left of the Williamsville formation.... Apr 11 was probably my last trip to the Bertie... more or less done collecting there... Leaving it to other folks that are even keener to hunt like Sam Ciurca from upstate NY and Tod.... they drive like 100 miles to be at the Bertie.... The Fiddlers Green formation where you find tiny eurypterids is mined out ... just a big hole filled with water... they crushed and processed the area of a foot ball field ... hundreds of eurypterids ground up to road gravel..... |

That is so sad to hear... too often, these sites are quarried out completely, and fossils ground up to dust because they're in the right sort of rock. Of course, if it wasn't for the quarry we wouldn't know about the things in the first place, but it's a shame there isn't a fair way of protecting sites like them and reimbursing the quarry owners - but I guess it would just cost too much. At least with important faunas like the Fiddlers' Green there have been a lot of collections, and the fauna is pretty well known overall. |

Peter.... Congratulations on the plant... The preservation looks pretty reasonable... sorry to hear about the quarry...Good sites are getting fewer and those that are left over collected...

Thanks Steve. Yes... one should never take anything for granted.... my other quarry in Arkona Devonian deposit... closed to collectors due to liability access granted once a year now.... under the control of CCFMS the local governing body ..... the number of collecting sites slowly diminishing and so fossil collectors will become fossils themselves....
