A) incredible article, one of the few where I didn’t feel compelled to give up and find the underlying paper. Well written, beautiful diagrams, appreciably concise. Thanks for posting!<p>B) The image of ~starlings hanging out with dinosaurs blew my mind. Talk about an odd juxtaposition! But I’m no dinosaur nerd, and haven’t seen the new generation of shows.<p>C) I just <i>have</i> to nitpick this to defend my buddies:<p><pre><code> Modern birds have some of the most advanced cognitive capabilities in the animal kingdom, comparable only with mammals. </code></pre> Maybe true for vertebrates, but octopuses deserve a spot on that list!

Reading this, I had to wonder what was &quot;opposite&quot; about these &quot;opposite birds&quot;. Apparently it&#x27;s how the shoulder blade (scapula) connects to the coracoid bone (a bone not present in therian mammals). From Wikipedia&#x27;s article on Enantiornithes:<p>&gt; Specifically, in the Enantiornithes, the scapula is concave and dish-shaped at this joint, and the coracoid is convex. In modern birds, the coracoscapular joint has a concave coracoid and convex scapula.
