>I find this interesting. I would like to know where you read or heard that clavicles were identified as interclavicles in those times. I happen to be writing an essay on the topic, and I would probably need a reference I could cite.
Osborn (1924) was the first to describe a theropod specimen with furcula preserved (Oviraptor philoceratops) and identified it as an interclavicle. He writes, "The interclavicle lies near its union with the extremely long and slender scapula."
