APPENDIX 1.
Crown width measurements in mm from modern Carcharodon carcharias (n=10) and Isurus oxyrinchus (n=1). Measurements are separated for the different regions preserved: upper left (UL), upper right (UR), lower left (LL), and lower right (LR). (Available as zipped file.)
APPENDIX 2.
Crown height measurements in mm from modern Carcharodon carcharias (n=10) and Isurus oxyrinchus (n=1). Measurements are separated for the different regions preserved: upper left (UL), upper right (UR), lower left (LL), and lower right (LR). * pathologic or broken. (Available as zipped file.)
APPENDIX 3.
Crown width measurements in mm of 11 fossil dentitions of Otodus and Carcharodon. Measurements are separated for the different regions preserved: upper left (UL), upper right (UR), lower left (LL), and lower right (LR). (Available as zipped file.)
APPENDIX 4.
Crown height measurements in mm of 11 fossil dentitions of Otodus and Carcharodon. Measurements are separated for the different regions preserved: upper left (UL), upper right (UR), lower left (LL), and lower right (LR). (Available as zipped file.)
APPENDIX 5.
Correction factors applied for missing teeth in fossil Carcharodon and Otodus dentitions. Correction factors for Carcharodon spp. are based on the mean percentage of the total summed crown width from a sample of 10 modern C. carcharias dentitions (see Figure 6A-B). Correction factors for adult Otodus megalodon are based on crown width proportions in UF-VP-311000. Correction factors for juvenile Otodus megalodon are based on crown width proportions in CH-31-46P. Correction factors for Otodus chubutensis are from GHC 3. (Available as zipped file.)
