Abstract
APPENDIX 4. — Specimen data of Crocodylidae by taxa for specimens with maximum body mass estimates for each member of the Shungura Formation. For Crocodylus Laurenti, 1768, measurement type “Dentary height” refers to the height of the mandible at the posteriormost level of the mandibular symphysis. For cf. Mecistops, “narrowest width” refers to the width of the narrowest part of the premaxilla, posterior to the premaxillary alveoli. For Euthecodon Fourtau, 1920, the measurement “Tooth spacing” is the average distance between the center of alveoli (dentary or maxilla) for all alveoli present in each specimen, excluding the anteriormost two.
