English: "Original dataset from DeSilva et al. (2021). Residuals from the regression are heavily skewed and heteroscedastic, and the temporal intervals between samples ranges from 2.85 million years to 100 years. Of the total of 987 total specimens in this 9.85 Ma analysis, 578 are in the final 100-year interval. Also shown is fitted regression lines from a linear model with 95% confidence intervals around the slope; changepoints were found using segmented R package at 2.1 ± 0.1 Ma, 1.3 ± 0.1 Ma, and respective slopes of 0.03 ± 0.01, 0.35 ± 0.04, 0.14 ± 0.13 surrounding changepoints. No changepoint was located at or around 3 ka that approached significance using Davies (1987) test after accounting for previously mentioned changepoints (p-value of any additional changepoints = 0.621)."
