Poison Spider Paleontology

Poison Spider Paleontology. . The Poison Spider Dinosaur Tracksite preserves the tracks of small to large theropod (meat-eating) dinosaurs. These unique tracks provide a glimpse into the past. Tracks help paleontologists understand the approximate size of the animal, the speed it was moving, the direction it was heading, and other interesting observations about its daily life that we would not be able to learn from bones alone. The track slabs fell from the Jurassic Navajo Sandstone cliffs, which rest on the brick red slopes of the Kayenta Formation., Be a Dinosaur Steward! , Please respect and protect these important tracks by not damaging them. Making casts of dinosaur tracks harms them and can lead to permanent destruction. It is also against the law. Photograph the tracks to document your experience, and leave this special site as you found it for others to enjoy., 190 Million Years... Gone in a Second , Dinosaur footprints are an irreplaceable part of America's heritage. The removal of any fossilized vertebrate footprints, bones, or teeth from public lands or molding, casting, or tracing fossils without a scientific research permit is against the law (Paleontological Resources Preservation Act of 2009). Carving, collecting, defacing, or altering any of these tracks prevents others from enjoying them and is illegal. Please report illegal activity to the BLM Moab Field Office at (435) 259-2100., Fossils , Vertebrate fossils and tracks are illegal to remove. Report looting or vandalium to a Bureau of Land Management ranger or other authority. Contact the Canyon Country District Office of the BLM at (435) 255-2100, Leave All Artifacts and Fossils , Keep discovery alive. Leave all artifacts and fossils where you find them so the next person can share the experience. It's illegal to move or take any artifact, including historic trash, along with invertebrate fossils and tracks, from public lands., Digging Is for Paleontologists , Leave dinosaur bones, tracks, fossils, and other paleontological remains where you find them so future visitors and scientists can benefit from these relics of the past., How You Can Help , If you find fossils (footprints, bones, or teeth):, . Leave them in place. , . Document the fossils with photos and a GPS reading, if possible, so that they can be found by land managers and scientists. , . Take notes about the area-what the rocks look like, any distinguishing landmarks, proximity to roads, and other useful information. , . Contact the appropriate public land management agency (Bureau of Land Management, National Park Service, U.S. Forest Service, state land agency, etc.) or local museum. , . Do not make replicas, tracings, molds, or casts, or pour anything into the tracks. These activities can damage the fossils. Instead, take pictures! By using overlapping photographs, create a model by using a 3D printer at your local library or from home., Captions , One Cliff, Many Stories , (Photo #1) Navajo Sandstone, Massive sand dune deposits (orange) with interdune lake deposita (blue). , Kayenta Formation, Stream channels running through desert sands. , (Photo #2) A variety of dinosaur footprints can be seen on this block that fell from the lower section of the cliff, at the base of the Navajo Sandstone. , (Photo #3) The smooth cliff faces formed by the Navajo Sandstone made the perfect surface for Native Americans to create petroglyphs. , (Photo #4) Two other large blocks which were once connected have fallen from the top of the cliff and are also covered with dinosaur footprints.
