The 2 new dinosaurs (feathered and green sauropod) have a new style of construction in which the body halves are split along the middle of the dinosurs' sides instead of down the middle along the spine/stomach. This allows all of the screws that hold the dinosaurs together to be placed on the underside instead of all on one side. This hides them from casual view unless the figure is flipped over. This is a vast improvement over the older style which left ugly screw holes visible on one side or the other of the dinosaurs (screw holes would be on whatever side of the dinosaur was facing the interior of the box).
The dragons have an entirely solid sonic welded construction which prevents the need for screws leaving the sculpt unmarred from any angle. The sculpts are beautifully rendered and have many different textures across each of the different dragon designs. They have the standard Lontic/Tedco articulation of swivel hips/arms/necks but lack the swivel tails found on the dinosaurs and other animals they produce. They also lack jaw articulation, but that is not surprising based on how small and slim most of the heads are sculpted. In the future, if they make more dragons, I would like to see some beefier headsculpts allowing for jaw articulation and some wing articulation as the wings are static on this first set.
For $13.99 per 6pk, I HIGHLY recommend the dragons. I have 6 sets so far and will probably get more next payday.
