FIGURE 2 in Testing hypothesis of skeletal unity using bone histology: The case of the sauropod remains from the Howe-Stephens and Howe Scott quarries (Morrison Formation, Wyoming, USA)
FIGURE 2. Detailed quarry map of the Howe Scott Quarry with finds from excavation seasons 1995-2003. The color coding reflects the hypothesis of skeletal unity based on field observations (Ayer, 2000). Sauropods are indicated in red in the legend. The arrows indicate the sampled bones used in this study. The quarry map was made by E. Premru, and provided by the Sauriermuseum Aathal, Aathal, Switzerland. Note that SMA M16/12-3 is not marked on the map due to a coordinate inaccuracy, which makes it impossible to correctly locate bone SMA M16/12-3 on the quarry map.
