Feathered Raptors

Well we made it to Friday. Admittedly, for many of us it was a short week.  But we can end it all the same with this piece from xkcd. It asks the question, are feathered dinosaurs scary? Back when they made the first Jurassic Park, we didn’t know how prevalent feathers were and so the dinosaurs were scaly. Now the Jurassic World films keep the dinosaurs scaly because, well, anti-science?

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.
