Re: T-rex arms

Emily Giffen has shown that the nerves that fed the arms of tyrannosaurs (and
carnotaurs) were as reduced as those of flightless birds with the most
reduced arms. Conclusion, tyrannosaurs probably did little if anything with
their arms. The arm nerve control of long armed theropods approached that of
flying birds.
