AchillesWF posted a topic in General Fossil DiscussionHello fellow Trilobite fossils collectors. I have 2 specimens in my collection that were specifically prepared 'with microfossils'. So, instead of blasting away everything around the specimen, the preparator took extra efforts to maintain the surrounding 'environment' that the specimen was contained within. I really like this preparation style, and am wondering why the Trilobite fossils I see for sale on the web, etc are much more likely to be just the specimen itself carved out of the matrix and leaving only scrapes, scratches or smoothed rock nearby. Does anyone know why there aren't mor
Mr.dogdad posted a topic in Fossil PreparationHello, I am hoping someone can help me! I have a Daspletosaurus tooth from the old man formation. It was found with a coarse, tar like substance stuck around the tooth (shown in photos) that won’t come off. I’ve tried rubbing acetone but that didn’t work. I tried picking a piece off but the enamel came with it. Are there any alternative methods I can use without risking any damage to the tooth?
I thought I'd tap the seasoned experts about this one before I go ahead and do something... permanent and boneheaded. What I have here is a Bellacartwrightia I found at Penn Dixie over a week ago. The cephalon is sticking out at a not so easy angle. On the top is a nice Bella pygidium I uncovered while chipping away from the top. I have no idea if the Bella cephalon continues. It does look like I'll have to sacrifice the pygidium. I'm just unsure how I should be going about seeing if I can expose the bottom one there as it seems to sit at a strange angle though the strata.
