The Musings seems to be have been on a bit of an unintentional roll for hadrosaur heads recently. There were some Lambeosaurus heads to go with Nipponosaurus but now here’s something of a flood. Steve Cohen, who kindly supplied a bunch of AMNH pterosaurs, has sent in this set of heads from the halls of the AMNH and it’s a nice example of the variety of crests and expansions seen in the group.
While some of these genera have made appearances on these pages before (like this Corythosaurus and while not shown here, don’t forget the amazing Tsintaosaurus) this is good chance to smush them all together and make them much easier to compare and contrast. A couple have also been flipped to put everything in left lateral view, though this means that the nicely labelled Saurolophus as the bottom is now covered in mirror writing.
Here then are (in order): Corythosaurus, Hypacrosaurus, Kritosaurus, Lambeosaurus, Prosaurolophus and finally Saurolophus.
