I know for people new to TFF like myself it would be nice to have a place where everyone can say what they're good at. It could be a specific era, location or just be dinosaurs or trilobites. This way people know who to ask if they want an ID for something very specific. I don't know if this already exists but if it doesn't here it is.
I don't have much fossil experience so other members would probably be a better fit but I would say my strength is teeth, shark teeth, dinosaur teeth, mammal teeth, any kind of teeth.
