Daeodon shoshonensis vs. Euoplocephalus tutus

[dinosauria101]

Daeodon shoshonensis
Daeodon, one of the largest, if not the largest, entelodont artiodactyls, lived 25-18 million years ago in North America. The 3.6 m (12 ft) long, about 1.8 m at the shoulder, 90 cm long skulled, 600 - 1000 kg mass animal strongly resembled a giant, monstrous pig or warthog, possessing huge jaws with prominent tusks and flaring cheekbones. It possibly was a huge, bone-crushing scavenger and predator, found at Agate Springs Quarry. It had long skull bones under its eyes and bony protrusions on the lower jaw, not dissimilar to the 'warts' of the warthog, which may have supported jaw muscles. The well-known genus Dinohyus ("terrible pig") has now been synonymized with Daeodon, as the latter is the earlier name, having priority.


Euoplocephalus tutus
Euoplocephalus (play /juːˌɒplɵˈsɛfələs/ ew-op-lo-sef-ə-ləs; Greek: eu-/ευ- meaning 'well', hoplo-/οπλο- meaning 'armed' and kephale/κεφαλη meaning 'head', "well-armored head") was one of the largest genera of ankylosaurian dinosaurs, at about the size of a small elephant. It is also the ankylosaurian with the best fossil record, so its extensive spiked armor, low-slung body and great club-like tail are well documented. Among the ankylosaurids, Euoplocephalus was exceeded in size only by Tarchia and Ankylosaurus. Euoplocephalus was 6 metres (20 ft) long and weighed about 2.5 tonnes (2.8 short tons). It was also 2.4 metres (7.9 ft) wide. The head and body of Euoplocephalus were covered with bony armor, except for parts of the limbs and possibly the distal tail. Much of this armor was made up of small ossicles. Larger flat scutes, conical plates, and disc-shaped plates were arranged in transverse bands among this pavement of ossicles. Two bands protected the dorsal and lateral surfaces of the neck, four were present across the front part of the torso, three protected the pelvis, and four were present on the anterior half of the tail. The banded arrangement is thought to have permitted some freedom of movement.

If Daeodon was a skull biter, like some modern day cats, it might the able to crush Euoplocephalus's skull with its huge and powerful jaws. The dinosaur's head looks rather small. Alternatively if it could cripple a leg or roll the dino over, it could win, although Daeodon likely could not grapple enough to easily roll over the dino, not to mention how heavy it is.

Of course, Euoplocephalus isn't going to be passive. While it was probably not as agile or fast as the "terrible pig," its low center of gravity and instincts probably allowed it to turn quickly and face an attacker with its crippling tail. Obviously its top is probably too armored and spikey for Daeodon to attack. Plus it was adapted to defend itself from attackers with big jaws, whereas Daeodon would not know how to react so such a strange creature.

At around 2.5 tons, it was significantly larger than Daeodon. I think a skull bite would probably be the best chance for Daeodon, but more often than not, it would be driven off or crippled by the dino. But not a mismatch, I'd say the dino wins 2/3 fights.

I actually favor Euoplocephalus here rather comfortably, as there are a couple of factors that I think would turn the tides in its tables the other 1/3 of the time.*
First of all, Ankylosaurus had a very heavily armored head that would have needed several skull bites from Tyrannosaurus to break through, and the gap between T rex's bite force and Ankylosaurus' armor strength is far less than Daeodon's bite and Euoplocephalus' armor. Second, if Euoplocephalus was to hunker down on the ground, both its head and legs would be completely protected, and it would simply have to wait for Daeodon to come within range of its tail. Thirdly, one hit from that club would definitely be more than enough to incapacitate Daeodon, going by some studies.* And fourth, I have a feeling the entelodont might mistake the Euoplocephalus' club for its head, and that would prove fatal.

*I do not consider this to be a match where Daeodon would immediately get obliterated, I just don't see a way for it to kill Euoplocephalus before being killed.

*I'll post the studies when I find them.

i favor the Euoplocephalus here as its gonna be very hard for the daeodon to bite him . but one tail swipe from the Euoplocephalus will really hurt the daeodon
