Hesperornithids small? Well, compared to mosasaurs, and to large terrestrial 
avian and non-avian theropods in general, but not when compared solely to 
other known, contemporaneous avian theropods. For Late Creatceous birds, 
hesperornithids were quite large, maxing out at about 1.8 m (if I've got that 
wrong, someone please correct me, as birds, even Cretaceous marine birds, are 
surely not my forte).
