However, Arbour & Currie (2015) questioned whether or not the sternum was preserved. The bone, tentatively identified as the left sternum, was found adjacent to various other elements and its boundaries remain unclear. The sternum could have possibly been displaced post-mortem, resulting in the anteriorly pointing posterolateral process.
However, Arbour & Currie (2015) questioned whether or not the breastbone was preserved. The rib cage element, tentatively identified as the left breastbone, was discovered adjacent to various other components and its limits remain indistinct. The breastbone may have been displaced after death, resulting in an anteriorly pointing outer lateral process.
