The resource I am using has the Tyrannosauridae listed under Subdivision ARCTOMETATARSALIA (Holtz, 1994), which in turn is listed under Division MANIRAPTORA (Gauthier, 1986). Is this correct? I had thought that the tyrannosaur family would be directly under the infraorder Tetanurae, along with the Megalosauridae and Allosauridae.
Gads, this can be confusing!!
Anyway, thanks for any possible help.....
