Re: So-called Sickle Claws

[brucet@mindspring.com (bruce thompson)]

        Has there been any informed speculation that some of these
sickle-claw dromeosaurs may have led an alpine lifestyle?  I'm just
wondering if the claw would be more of a help or a hindrance on rocky
hillsides.  Or maybe they were just one of nature's "nice but not
necessary" adaptions, like saber teeth in felids.
