This paper reexamines data on the relationship between carapace length and body mass in the desert tortoise (Testudo sulcata) from a previous study. The authors calculate new allometric equations using the original data and find exponents of 0.36 and 0.39, which disagree with the previous study's calculation of 0.91. These new exponents are closer to what would be expected based on other research on chelonian allometry. The authors conclude the previous study likely contained errors in their calculations and analysis of this tortoise species' measurements.
