Where the bones are, and whether you may legally pick anything up: every site colour-coded by what the law actually allows, from open fee-digs to look-only federal ground.
Sometimes. On federal land you may collect reasonable amounts of common invertebrate and plant fossils for personal use, but vertebrate fossils require a permit and never leave public ownership. Each site is colour-coded by what is allowed.
Fee-dig quarries and some BLM land allow it. National parks and monuments do not. The Paleontological Resources Preservation Act of 2009 is the governing rule.
