AFAIK only one crocodylomorph, *Gracilisuchus stipanicicorum* (the
basalmost one AFAIK), is thought to have been bipedal (others say
semibipedal). I don't know anything about hallopodids, except that they are
from the Morrison formation, Marsh classified them with coelurosaurs, and
they are now regarded as the last sphenosuchians or suchlike.
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 ??
