I thought the sphenosuchians were facultatively bipedal - which explains the 
disparity between the lengths of the arms and legs. Eg. Gracilisuchus (which 
may be a rauisuchian), Saltoposuchus and Sphenosuchus.

Hallopus is not (AFAIK) a sphenosuchian, thought it is a crocodylomorph. 
Crocodylian classification confuses me, very much.

P.S. On a totally separate topic: Why is it people find it so easy to work 
out how to subscribe to this list, but find it impossible to work out how to 
get off it ??
