The New Dinosaur Family Tree

Today’s post is not a particular great graphic in that it is far from revolutionary. Instead, you could say it far more evolutionary. A new finding by Matthew Baron posits a rather unusual dinosaur named Chilesaurus, discovered in Chile as its name suggests, is actually a cousin to both the tyrannosaurs and raptors as well as to triceratops. (Get the joke now?)

After I read the story I had to dig around for a graphic that made more sense than this BBC graphic. Why? Well, the way the article was written, it read more that the Chilesaurus actually falls after the theropods, but before the ornithischians as a cousin-like species. This BBC graphic makes it appear as a third sibling.

Really, I just want the velociraptor…

So in the Daily Mail, we have this graphic, credit given to Matthew Baron, that shows how the theropods branched out, but that Chilesaurus branched out after them and yet still provided ancestral traits to the ornithischians.

Or utahraptors. Give me utahraptors.
Or utahraptors. Give me utahraptors.

As both articles point out, this is not settled science and many disagree with the new arrangement. But as a person who grew up fascinated by dinosaurs, these kinds of stories are just fantastic.

Credit for the piece goes to Matt Baron.

I am a graphic designer who focuses on information design. My day job? I am the data visualisation manager for the Federal Reserve Bank of Philadelphia. (This blog is my something I do on my own time and does not represent the views of the Fed, blah blah blah legal stuff.) And with my main interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I enjoy cooking and reading and am interested in various subjects from history and geography to politics to science to the arts. And I allow all of them to influence my work.
