Introduction & Methodology Since Barbatteius vremiri is known exclusively from a single holotype specimen, establishing the upper size limits of the species requires statistical modeling. To counter the "holotype bias" (the uncertainty of whether our single fossil represents a juvenile, an average adult, or a genetic outlier), we can use the extant and subfossil record of island-dwelling teiids. This model utilizes data from Bochaton et al. (2017) regarding Pholidoscelis remains from Basse-Terre Of snout-vent length, that does not count with the tail. The histogram provides three critical biological benchmarks based on a sample size of 85: Population Mean: 143 mm Minimal Theoretical Maximal Size 1 (MTMS 1 - Young/Minimum Mature Adult): 205 mm Minimal Theoretical Maximal Size 2 (MTMS 2 - Absolute Maximum Size): 243 mm We apply these exact scaling ratios to the Barbatteius vremiri holotype metrics (26 cm SLV, 80 cm TL) For volumetric mass estimation, we use the standard allometric equation for robust, armored…
