Supplemental Material: Crushed turtle shells: Proxies for lithification and burial-depth histories
Figure S1: Comparison of lithification depths derived from plastron length and carapace length. Table S1: Plastron size data and plastron-based burial-depth estimates. Table S2: Carapace size data and carapace-based burial-depth estimates. Table S3: Different surface porosity values used to estimate burial depth. Table S4: Outcomes of similarity tests between plastron- and carapace-based depth estimates. Plastron and carapace depth models are similar. Item S1: Reconstruction of thickness of overlying sediment packages. Item S2: R Script.
