Do dinosaurs have wishbones

They did have a wishbone. Also a T-Rex, Velociraptor, and Allosaurus

Well, in 1927, Gerhard Heilmann first discussed the idea that dinosaurs evolved

into birds, however, this idea was discredited during the time, because no fossilized evidence of wishbones were present in theropodic dinosaur fossils, unlike birds. However, in the 1970s, collar and wishbones were found in theropods, such as the dromaeosaurs (raptors) and tyrannosaurs, creating the modern view of dinosaurs evolution into birds.
