the sideways expansion at the front of this vertebra to be due to crushing, and pointed out that such preservation where fragile, yet well-preserved bones are associated with damaged material of the same individual is known from other vertebrate fossils in the same level. They identified the frontmost vertebra as a C5 because this is usually the longest cervical vertebra in pterosaurs, their length decreasing hindward. In 2007 paleontologist Alexander W. A. Kellner and colleagues noted that Phosphatodraco was one of the most interesting azhdarchids found in Africa, but used cautious language about the original interpretation of the vertebrae. Kellner suggested in 2010 that interpretation of the holotype specimen had been affected by taphonomy (changes during decay and fossilisation); he instead proposed that the element originally described as a fifth cervical vertebra was actually the third and fourth vertebrae which had been compressed together, giving the impression that they were a single vertebra broken in the middle. This would shift the order of the vertebrae to C3–C8, and though this did not change the validity of the taxon (its distinctness being based on its stratigraphy, geography, and morphology), Kellner noted that the diagnosis (the suite of features that distinguish a taxon) and size estimate had to be reevaluated. The frontmost cervical vertebrae which are missing from Phosphatodraco in either scheme are the atlas (C1, which connects with the back of the skull) and the axis (C2). Subsequent articles from 2011 and 2015 with Kellner among the co-authorship have concurred with Kellner's interpretation. Paleontologist Alexander Averianov disagreed with Kellner's reinterpretation of the cervical vertebrae in 2014, and considered the original description accurate. A 2015 article by paleontologist Mátyás Vremir and colleagues called the issue "controversial" and considered the specimen too crushed for proper comparison, and Martill and Markus Moser concurred with this in 2018. Paleontologists Darren Naish and Mark P. Witton (the co-authors of Vremir's article) followed Kellner's interpretation in 2017. Paleontologist Rodrigo V. Pêgas and colleagues also followed Kellner's order in 2021. Though the palaeontologist Alexandru A. Solomon and colleagues noted the suggested change in interpretation of the holotype order in 2019, they stated that even if the reinterpretation was correct, the specimen was too damaged for comparison with the single known cervical vertebra of their new genus Albadraco. Description In their 2003 description, Pereda-Suberbiola and colleagues estimated Phosphatodraco to have had a wingspan close to , based on comparison
