 The absence of clavicles in dinosaurs became the orthodox view despite the discovery of clavicles in the primitive theropod "Segisaurus" in 1936.The next report of clavicles in a dinosaur was in a Russian article in 1983.Contrary to what Heilmann believed, paleontologists now accept that clavicles and in most cases furculae are a standard feature not just of theropods but of saurischian dinosaurs.
