Dataset from thesis entitled "Disease in the Cretaceous: A comparative study of Iguanodon and hadrosaur palaeopathology"

  • Filippo Bertozzo (Creator)



The following dataset represents the list of material and supplementary analyses for the thesis entitled “Disease in the Cretaceous - A Comparative Study of Iguanodon and Hadrosaur Palaeopathology”, reporting all the specimens from the visited museum collections and those published in the literature.

Appendix 1 is a list of all the palaeopathological specimens known from the ornithopod literature, subdivided in 11 body parts.

Appendices 2 to 4 represent the complete list of studied material, added to the literature revision, that describes each pathological element in the three morphotypes (corresponding to basal (e.g. Dryosaurus), “intermediate” (e.g. Iguanodon) and derived ornithopods e.g. (Edmontosaurus)). The specimens are subdivided into 16 body parts, as their identification was done personally, helping to discern between, for example, middle to distal caudals. Graphical representations are proposed at the end of each appendix.

In Appendix 5, specimens belonging to Morphotype C from four museum collections are compared to each other, treated as different “populations”, with graphical distributions and codification for the linear regression, the latter done in the software SPSS.

Appendix 6 is a complete schematical description of all caudal vertebrae from Morphotype C, reporting measurements and type of injuries/deformations. Although the studied specimens are listed in Appendix 2 to 4, their osteology is extensively described in Appendix 7, grouped per body regions between the three morphotypes. Some of the most peculiar and/or uncertain specimens were scanned via a microCT device, and their descriptions are reported in Appendix 8. A wide number of caudal neural spines from Appendix 4 are extensively described in Appendix 9 and listed in tables together with the angulation of the bending of the pathological spines.

The final Appendix 10 corresponds to the published article about the palaeopathologies detected in the holotype of Parasaurolophus walkeri during the collection visit at the Royal Ontario Museum (Canada). The palaeopathological analysis provided an unexpected reevaluation of the neck musculature of the species.
