Dinosaur "baculae"

I should be extremely surprised to learn that any dinosaur had a baculum, as
this is a feature of the mammalian penis which (by virtue of its being
divorced from the digestive system except in Monotremata which I think lack
baculae) is not exactly homologous to the intromittent organ of any
non-mammalian vertebrate.
