You Are Having Coffee with a Couple of Friends

Not Answered

You are having coffee with a couple of friends. One says, "I saw a beautiful dinosaur in my yard this morning." The other one says, "You're crazy, you couldn't have seen a dinosaur!" Use the phylogeny below, which includes birds and four different dinosaur genera, and the logic of phylogenetic systematics to argue that maybe your first friend isn't so crazy after all.
