Galton (1999) reports that the distal femur is 261
mm across. Comparing this to 102 mm in the holotype of Herrerasaurus,
which is estimated at 3.5 meters long (using Novas, 1993), results in an
estimated length of 9 meters. Using Paul's (1988) mass estimate for the
Herrerasaurus holotype results in a weight of about 3.5 tons. Of course,
Aliwalia seems to be in the coelophysoid + neotheropod clade, making comparisons
with Herrerasaurus less accurate, but these estimates are probably not far
off.
