Re: Building Blocks of T. rex
My favorite is the recent(?) announcement that T. rex exhibits considerable
sexual dimorphism, *and* that the really big T. rex specimens are the females.
Our summer campers (ages 9-13) really thought this was cool.
However, this info was shared by one of our guest speakers in anecdotal form
only. Mayhap the professionals can steer us to a reference, please?
