[note- I'm going to use the term "therizinosaur" in preference to "segnosaur"]

        An interesting thought, but bamboo is a grass and grasses lacked any
significant presence during the Mesozoic. Therizinosaur claws look like good
weapons for interspecific combat and defense, but may ahve also served some
feeding-related role. My question is, what is known of the therizinosaur
humerus articulation with the shoulder girdle? What movements could have
been achieved in addition to locomotor activity?
