ex1120: Was Tyrannosaurus Rex Warm-Blooded?

Description

Data are the isotopic composition of structural bone carbonate ($X$) and the isotopic composition of the coexisting calcite cements ($Y$) in 18 bone samples from a specimen of the dinosaur Tyrannosaurus rex. Evidence that the mean of $Y$ is positively associated with $X$ was used in an argument that the metabolic rate of this dinosaur resembled warm-blooded more than cold-blooded animals.
