How about this?
An armored, heavily built hadrosaurid. It retains the thumb spikes, and it’s back is covered with rows of scutes, almost appearing like a shell, with two rows of small spikes aligned on either side of its spine. Two larger spikes jut out just above its shoulders and at a slight downward angle, with each nearly the full length of its forearms.
It’s skull is also armored, and is shaped like the Tenontorex’s (minus the crest of course), but has nasal sacs just behind its nostrils that it inflates for display, intimidation, and communication across longer distances between individuals and herds.
Its color is deep blue, with a slight shade of emerald green and purple stripe running from the bottom of the neck to the tip of its tail.
