Turtle body size evolution is determined by lineage-specific specializations rather than global trends. [PDF]

open access: yesEcol Evol, 2023
In this work, we characterize deep‐time patterns of body evolution in turtles (Testudinata), using the most comprehensive dataset to date and employing different comparative methods. Our results suggest that through‐time patterns of turtle body evolution were determined by lineage‐specific specializations, such as habitat choice.
