tyrannosaurid is (IIRC) _Alectrosaurus_ --
medium-sized (again, IIRC). There are a number of
possible, earlier tyrannosauroids, some (_Iliosuchus_)
very small, none very large. None are definite, but
you can find them at

  What about *Siamotyrannus*? Am having trouble
finding the ref for this guy, being in Nature or
Science, and as I am going to the univ. library to
fetch these journals tomorrow, am wondering if anyone
can post it for me?

  Anyway, *Siamo.* shows several tyrannosauroid
features, including the strong vertical ridge, shape
of the ilium, large pubic boot, but I know virtually
nothing else.
