DevonianDigger Posted March 17, 2019 Share Posted March 17, 2019 If they're finding complete examples, I would go where they are going. Persistence pays off. It's not quite as simple as just saying "go here" and you will find complete fossils. If there are pieces of what you're looking for, I would say just keep looking! 4 Jay A.
