This dataset, Tsd_turtle, is a data frame containing extensive information on temperature-dependent sex determination (TSD) in reptiles. The dataset includes 2,738 observations and 48 variables, covering species, location, incubation temperatures, egg and hatchling measurements, sex ratios, clutch information, and references. All values are preserved as in the original source, with no modifications.

Details
The dataset name has been kept as 'Tsd_turtle' to avoid confusion with other datasets in the R ecosystem. This naming convention helps distinguish this dataset as part of the BioWorldR package and assists users in identifying its specific characteristics. The suffix 'df' is not used here because the dataset is identified by its function within BioWorldR. The original content has not been modified.
