Abstract
APPENDIX 2. — Linear regression equations used to estimate skull length for crocodylian specimens;total body length for vertebral regressions from Iijima & Kubo (2020). * measurement for final two rows, vertebral centrum length, is in mm. Abbreviations: KNM, National Museums of Kenya; N, number of specimens; NHML, Natural History Museum (London); SL, skull length; TBI, Turkana Basin Insitute; TL, total body length.
