Baby Sauropod Trackways Discovered in the Western United States
A set of dinosaur trackways dating from the Late Jurassic have been identified as having been made by baby Sauropods, (long-necked dinosaurs). The footprints suggest that these are the trace fossils of the youngest Sauropods known to science and they are providing scientists with an insight into dinosaur family life from approximately 145 million years ago.
Dinosaur trackways are exceptionally rare. These trace fossils can tell palaeontologists a lot about the behaviour of the animals that created them, unlike body fossils such as bones, which can be transported many miles before deposition, when you look at a footprint in the field, you are looking where a dinosaur actually walked, or in this instance ran!

Everything Dinosaur team members reported on a similar discovery, back in 2008, when a series of baby Sauropod trackways were unearthed from Lower Cretaceous sediments in South Korea.
