I got this box of fossil from auction at the low price of £21. The collection is old and dates between 1933 and 1944 . Some of the collection has labels but sadly others are lost or mixed up. Most of the locations are from Yorkshire but there is also Oxfordshire and the midlands. I purchased this lot because of the small collection of corals. The some of the corals have been cut and polished. I did re-polished most of them because they seamed to have a coating to finish the process. There is also some nice plant material from coal seams it is good to get this material from now in the Uk lost localities . Please if anyone can help me fill in the blanks I have added locations I have the labels too, Robin Hoods Bay, Leeds, Wakefield , Whitby , Buckinghamshire and Midlands. I will do a better list of locations when Mrs R gets home because I can’t read some of the hand writing. I think it is a great little collection. Thanks for looking. Cheers Bobby corals 1) 2) 3) 4) 5) 6) 7) 8)

It's so much fun when you unpack your fossils from a trip, sit down with a smug self satisfied look on your face and then suddenly you say loudly. HEY! Where is the plate with the spots? And my Equisetum? You dash over to the unpacked, unwashed, moulding pile of camping gear that should have been cleaned up days ago, dig around in it, and there it is! Another box of fossils! Yahoo more things to show my buddies on the forum. This is my trove from the Eocene Lake deposits of Princeton B.C. Canada. The very cool thing about the fossils at this location according to Dr. Ruth Stockey's research, the fossils are permineralized. Unlike the compression fossils many of us are used to, these fossils have had their mass replaced by silica. From her article she says" they are preserved in 3 dimensions in a solid matrix of silica that formed from the infiltration of the intercellular spaces and cells with silicic acid - a process that resulted from periodic volcanic eruptions" According to this book, sometimes you can't really see the fossil unless you etch it with hydrofloric acid. Hmmm.. Do I have any of that lying around? I have a little stale vinegar. Maybe I'll leave that process to the experts. Here are the cool things from box #7 This looks like some kind of leaf maybe? This is what they mean by permineralized as it is dimensional and who knows what it might be. This looks like seeds from a fruit. They are actually raised as if you could pick them off the surface of the plate. And here is the very weirdest thing I found (and I do like my fossils on the weird side) This has spots all over the surface. Its like that geological thing where minerals invade and fill the holes and spaces in existing rock- vesicular? I put in a little diagram to show that the spots are solid in x section and are slightly raised. They are about 1/8th inch across. Anyone hazard a guess on that? More fun stuff from the wilds of Canada! Fran
