Spreadsheet for mass property calculations: Tarbosaurus bataar ZPAL MgD-I/4
This spreadsheet includes all equations necessary for calculating mass properties from lateral and coronal reconstructions. Contact author Eric Snively (email@example.com) for instructions.
Figure for digitizing Tarbosaurus bataar (ZPAL MgD I/4), after Paul (2010) and Hurum and Sabath (2003).
This image was used for digitizing outlines and calculating mass properties of Tarbosaurus bataar (ZPAL MgD I/4). The skull is tilted down in lateral view, and shortened in dorsal view to match the length. See text for details. The tail is restores as moderately wide, after Persons and Currie (2011).
Calculations of rotational inertia for body + leg
This spreadsheet has all variables and equations for calculating rotational inertia of the body and swing leg pivoting above a stance foot, for all specimens. The animal has just pushed off with its swing leg, whose center of mass is now ventrolateral to the acetabulum.
R code for replicating phylogenetic comparative results
Running the R scripts in this zip folder will enable replication of results, and modifying the code will enable execution of the methods with other questions and data.
PGLS results with both legs planted, with labeled data points
This figure is the same as text Fig. 4, but with full labels for all data points including taxa, and juvenile or adult status and specimen numbers for multi-specimen taxa.
