in the preceding vertebrae. The following C7 vertebra (Kellner's C6) is visible in bottom view, is missing the hind part, the preserved part being long, and the complete length perhaps being the same or shorter as the preceding C6. Its prezygapophyses are similar to those of the preceding vertebra, and the cotyle is oval and compressed from top to bottom. There is a sulcus below the left prezygapophys, apparently without a ridge extending hindward. The centrum bulges slightly hindward, becoming narrower at its mid-length. The postzygapophyses are well-developed, and diverge widely from the longitudinal midline of the centrum. A small protuberance between the postzygapophyses perhaps indicates where the upper margin of the neural canal (through which the spinal cord passed) was located, though its features cannot be accurately determined. The next to last vertebra is C8 (Kellner's C7) which is visible in side view, and despite missing some of the front, the centrum is very elongated, measuring . The most notable feature of this vertebra is its tall neural spine, which is placed at its hindmost part. The neural spine is high measured from the upper surface of the postzygapophys to the top, almost the same height as the centrum, which is . The front and hind margins of the neural spine are vertically parallel to each other, and its top is truncated in a square shape, and perpendicular to the side edges. The left postzygapophys is located at the base of the hind end of the neural arch (which forms the arch of bone through which the spinal cord passed). It is similar to the same vertebra of Quetzalcoatlus in that the neural spine is square on top, but differs in being placed so far back. The left postexaphophyseal process is well-developed at the back and below, but does not extend past the condyle as it does in the preceding vertebrae. The last vertebra is the C9 according to Pereda-Suberbiola and colleagues (Kellner's C8, which is visible in hind view, and its preserved part is high. Its neural arch has a large neural spine and well-developed transverse processes (which projected from the sides of the centrum and acted as attachment points for muscles and ligaments). The neural spine terminates in a blunt process above, and the hind side of the neural spine has an oval depression, which has thick vertical edges at its sides. The transverse processes are long
