foramina are discernable, closely to one another (0.5 cm), on the floor of the former neural canal ( Figure 8A View FIGURE 8 ). The neurocentral articular facet is strongly eroded, but still slightly elevated. In lateral view, the centrum is slightly medially constricted. The base of a process for rib articulation is still preserved, measuring 0.5 cm in mediolateral length. The process is positioned on the dorsal half of the centrum, close to the neurocentral articular facet. In lateral view, the process is positioned on the mid-length of the centrum and triangular in cross section. A circular foramen with a width and height of 0.3 cm is located on the ventral half of the centrum. The circular foramen is ventrally to the process. The other lateral side of the centrum bears such a foramen on a slightly higher position. One half of the ventral side of the centrum is strongly eroded, but together with the anterior and posterior articular facet morphology, the centrum gives the impression of having borne an anteroposteriorly oriented keel as ventralmost edge. Furthermore, as the microCT data suggest, three additional foramina are present on the ventral side of the centrum, close to or within the ventral eroded patch. Hence, the internal network within the centrum bears two foramina dorsally and five ventrolaterally to ventrally, resulting in a hand-like appearance ( Figure 8B, C View FIGURE 8 ). The individual canals seem to have related to each other close to the core of the centrum. The whole network occupies only an anteroposteriorly narrow space and is not exactly situated on the anteroposterior mid-length of the centrum ( Figure 8D View FIGURE 8 ).
