Lythronax argestes v Denversaurus schlessmani
#1
Denversaurus schlessmani
Denversaurus (meaning "Denver lizard") is a genus of herbivorous nodosaurid ankylosaurian dinosaur from the Late Cretaceous (late Maastrichtian) of western North America. Although at one point treated as a junior synonym of Edmontonia by some taxonomists, current research indicates that it is a distinct nodosaurid genus. In 2010, American paleontologist Gregory S. Paul estimated the length of Denversaurus at six meters and its weight at three tonnes. American paleontologist Robert T. Bakker considered Denversaurus distinct from Edmontonia and Chassternbergia in having a skull that was wide at the rear and a more rearward position of the eye sockets. The holotype skull has a length of 496 millimetres and a rear width of 346 millimetres. In the referred specimen AMNH 3076 these proportions are less extreme, measuring 395 millimetres long with a rear width of 220 millimetre. According to American paleontologist Kenneth Carpenter, the greater width of both the holotype and the referred specimen was due to crushing.
Vertebrate anatomist and paleontologist Michael Burns in 2015 published an abstract that concluded that Denversaurus was different from Edmontonia but similar to Panoplosaurus in having inflated, convex, cranial sculpturing with visible sulci, or troughs, between individual top skull armour elements, but is distinct from Panoplosaurus in having a relatively wider snout.

Lythronax argestes
Lythronax is a genus of tyrannosaurid theropod dinosaur that lived around 80.6 to 79.9 million years ago in what is now southern Utah, USA. The generic name is derived from the Greek words lythron meaning "gore" and anax meaning "king". Lythronax was a large sized, moderately-built, ground-dwelling, bipedal carnivore that could grow up to an estimated 8 m (26.2 ft) in length and weighed 2.5 tonnes (5,500 lb).
L. argestes is the oldest known tyrannosaurid, based on its stratigraphic position. It is known from a specimen thought to be from a single adult that consists of a mostly complete skull, both pubic bones, a tibia, fibula, and metatarsal II and IV from the left hindlimb, as well as an assortment of other bones. Its skull anatomy indicates that, like Tyrannosaurus, Lythronax had both eyes facing the front, giving it depth perception. It has been estimated that Lythronax would have been about 7.3 m (24.0 ft) long, with a weight of around 2.5 tonnes (5,500 lb), based on comparisons to close relatives, and had a large skull filled with sharp teeth. The rostrum of its skull is comparatively short, since it makes up less than two thirds of the total skull length. The whole skull is very broad, and is only about 2.5 times as long as it is wide. Overall, the skull is morphologically most similar to that of Tyrannosaurus and Tarbosaurus. Its robust maxilla possessed a heterodont dentition, as its first five teeth are a lot larger than the other six. Like other tyrannosaurids, Lythronax has large, distally expanded pubic boot which is approximately 60% the length of the pubic bone. The postcranial morphology is similar to that of other tyrannosaurids.

After reading through the old T.rex vs ankylosaurs, I thought we could have a match of animals that were less powerful.

The denvasaurus would win most times. It is heavily armored and its club tail can cause serious damage.

Denversaurus was a nodosaurid. It completely lacked a tail club, though it might have still whipped its tail at predators. Nodosaurids had large shoulder spikes that they most likely used more in defense, although the bone cores in Denversaurus don't seem to be as large as they are in say, Edmontonia. Maybe the keratin sheathes could have gotten them to be significantly large.

This one seems a lot more even then the ankylosaurus vs Tyrannosaurus. For the denver doesn't posses the bone shattering club. Those shoulder spikes could deal some damage. The real question is though, could the tyrannosaurid break through it's armor before getting stabbed in the leg? So far, i'm favoring none or the other.
