Were tyrannosaurids, therizinosaurids, dromaeosaurids, compsognathids, oviraptorids and ornithomimids related to birds?

The birds (aves) broke off early from the main stream Dinos. I haven't bothered to check each on your list, but tyrannosaurs came well after birds. They're cousins 40 million years removed. Oviraptorids came from the group that birds did. Birds closest relatives are the crocs. Then birds and crocs group with turtles. Then birds, crocs and turtles group with lizards. Blah, blah, blah.Source(s): [n] = 10ⁿ

All living things are related if you look far enough back in time. You need to rephrase your question.

Really its the other way round. "Are birds related to......?" Birds are the present day creatures who might be related to all those ancient life-forms.
