Carnivorous dinosaurs other than the famous t-rex and spinosaurus..

Some basal megalosauroids such as Xuanhanosaurus (link), Marshosaurus (link), and Eustreptospondylus (link) seem to have proportionally MASSIVE heads (all 3 are around 200 kg yet their skulls are all 60 cm at least), yet their forearms are also very large as well, about the same proportionally as a lion, tiger or grizzly bear, 60-65 cm long for a 200-250+ kg specimen of any of the 3 (link, link).
I suspect these animals may have been more efficient predators than modern grappling carnivores such as big cats or bears, as well as more efficient than modern large jawed predators such as canines, hyenas, or crocodilians, since they have the large, deadly jaws of a canine, hyena or crocodile, but also the powerful grappling forelimbs of a big cat or bear.
