In Depth First discovered in 2013, and named in 2015, Morelladon made headlines towards the end of 2015 as a rare example of a sailbacked dinosaur. Though dubbed a sailback, this sail was likely more like a hump as the neural spines of the vertebrae that supported it were very robust. These are way beyond … Read more

Tuojiangosaurus itself is seen as a basal (primitive) form that displays a standard stegosaurid shape and posture while retaining features that would be lost in later genera. Tuojiangosaurus seems to have been limited to a … Read more

Though only known from partial remains and with much of the neck missing, available fossils do show that Pulanesaura was already developing the very long neck that would be a signature feature of the sauropods by the … Read more
In Depth Huangshanlong is a genus of sauropod dinosaur that lived in China during the mid Jurassic. Unfortunately, because only a couple of forelimb bones have been used to describe the genus, not much can be said about this dinosaur. The describers were of the opinion that Huangshanlong repesented a mamenchisaurid sauropod, a type of … Read more
In Depth When described in 2015, Probrachylophosaurus made headlines around the world, when it was often dubbed ‘superduck’.

Probrachylophosaurus itself has a much smaller triangular crest which … Read more
