Borson's Mastodon - Zygolophodon borsoni
Zygolophodon is an extinct genus of African, Asian, North American and European mammutid that lived from the Miocene to the Middle Pleistocene. It may have evolved from Tetralophodon. While collecting fossils in the Clarno Formation of Oregon during 1941, noted paleobotanists Alonzo W. Hancock and Chester A. Arnold recovered the most complete Zygolophodon skull known at the time.
Zygolophodon borsoni is a large species that was sometimes considered as a species of Mammut, and it was one of the largest terrestrial mammals of all time. With a shoulder height of about 3.9–4.1 metres (12.8–13.5 ft) and a weight of about 14–16 tonnes (15.4–17.6 short tons), it approached the size of Paraceratherium, and was heavier than several sauropod dinosaurs.

Triceratops horridus
Triceratops ( /traɪˈsɛrətɒps/ try-serr-ə-tops) is a genus of herbivorous ceratopsid dinosaur which lived during the late Maastrichtian stage of the Late Cretaceous Period, around 68 to 65 million years ago (Mya) in what is now North America. It was one of the last dinosaur genera to appear before the great Cretaceous–Paleogene extinction event. The term Triceratops, which literally means "three-horned face," is derived from the Greek τρί- (tri-) meaning "three", κέρας (kéras) meaning "horn", and ὤψ (ops) meaning "face". Bearing a large bony frill and three horns on its large four-legged body, and conjuring similarities with the modern rhinoceros, Triceratops is one of the most recognizable of all dinosaurs and the best known ceratopsid. It shared the landscape with and was preyed upon by the fearsome Tyrannosaurus, though it is less certain that the two did battle in the manner often depicted in traditional museum displays and popular images. The exact placement of the Triceratops genus within the ceratopsid group has been debated by paleontologists. Two species, T. horridus and T. prorsus, are considered valid although many other species have been named. Recent research suggests that the contemporaneous Torosaurus, a ceratopsid long regarded as a separate genus, actually represents Triceratops in its mature form. Triceratops has been documented by numerous remains collected since the genus was first described in 1889, including at least one complete individual skeleton. Paleontologist John Scannella observed: "It is hard to walk out into the Hell Creek Formation and not stumble upon a Triceratops weathering out of a hillside." Forty-seven complete or partial skulls were discovered in just that area during the decade 2000–2010. Specimens representing life stages from hatchling to adult have been found. The function of the frills and three distinctive facial horns has long inspired debate. Traditionally these have been viewed as defensive weapons against predators. More recent theories, noting the presence of blood vessels in the skull bones of ceratopsids, find it more probable that these features were primarily used in identification, courtship and dominance displays, much like the antlers and horns of modern reindeer, mountain goats, or rhinoceros beetles. The theory finds additional support if Torosaurus represents the mature form of Triceratops, as this would mean the frill also developed holes (fenestrae) as individuals reached maturity, rendering the structure more useful for display than defense. Individual Triceratops are estimated to have reached about 7.9 to 9.0 m (26.0–29.5 ft) in length, 2.9 to 3.0 m (9.5–9.8 ft) in height, and 6.1–12.0 tonnes (13,000–26,000 lb) in weight. The most distinctive feature is their large skull, among the largest of all land animals. The largest known skull (specimen BYU 12183) is estimated to have been 2.5 metres (8.2 ft) in length when complete, and could reach almost a third of the length of the entire animal. It bore a single horn on the snout, above the nostrils, and a pair of horns approximately 1 m (3 ft) long, with one above each eye. To the rear of the skull was a relatively short, bony frill, adorned with epoccipitals in some specimens. Most other ceratopsids had large fenestrae in their frills, while those of Triceratops were noticeably solid. The skin of Triceratops was unusual compared to other dinosaurs. Skin impressions from an as-yet undescribed specimen show that some species may have been covered in bristle-like structures, similar to the more primitive ceratopsian Psittacosaurus.

They seem to be the same weight on average, but Zygolophodon has very long tusks, and they aren't curved, no they're straight and seem very adept at impaling. However, if they're so long, I don't really know if that means they'll more easily break than a normal elephant's tusk. If that is the case, then Triceratops would likely break the tusks and likely acquire the edge. If not, then it might be harder for Triceratops to confront the mastodon with such large tusks. For now, I'd still probably favor Triceratops 51-55%, if not a 50/50.

Based on the pic in the opening post, the tusks are so long they look dysfunctional!

Well, if that was the case, it would likely be a mismatch.

triceratops wins, the zygolophodon's tusks are to long and thin, it can't really ram into the triceratops without its horns breaking.

What are those tusks really going to even be touching, when they both hit each other? Triceratops wins.

triceratops wins. it has a neck frill and the tusks Zygolophodon possesses look so thin and long that they wouldn't be able to be used effectively.

That would be the case if it were a 12 tonne Triceratops. A 6 tonne Triceratops would be a relatively good match, but I can see the dinosaur winning if these tusks really were dysfunctional.

Edit 8/16/16: According to Larramendi (2015), Zygolophodon weighed 14-16t, which is larger than any Triceratops. If true, this should allow it to win more often than not easily, combat-practical tusks or not.

I found the tusks of zygolophodon, they are not as thin as the description portrays it to be, they are actually quite thick and I doubt they would be easy to snap as they are in my opinion, capable to absorb the impact from similiar sized zygolophodon males, zygolophodon its the heavier of the two as they weight from 14-16 tons (asier Larramendi), while I think the average triceratops weighted 6 to 12 tons ( the average IMO would be 8-10 tons) meaning that zygolophodon would overpower the triceraptops or pummel the triceratops with its tusks which just stabbed it.

Sorry for my bad english, also the image of borsoni in the description looks rather gracile for a mammut/mastodon.

Very gracile even for extant elephants.

This is better image, resembling a wide sturdy build like a true mammut, with the tusks resembling more to the images I posted above.

Even in the picture in the OP, the tusks look more "awkward" than "fragile" to me. How useful would they really be in close quarters combat? And if they wouldn't be that useful "up close and personal," how effective would they be at keeping the adversary at a distance?

Well the base of tusks can be use to lock with other horns and tusks, and the tusks can be used for sweeping and bashing to keep the other animal at bay and thanks to the size advantage it can be effective, it could also use size to shake off smaller animals, well depending which animal is it.

No size advantage is insurmountable if the larger animal doesn't have effective weaponry.

We need a visual size comparison here.

I don't think that lateral sweeping of the tusks would do much damage. By contrast, a good gore from Trike's nasal horn could be devastating. (as Trikes got older, their brow horns curved forwards and downwards. Meanwhile, the nasal horn got longer and stouter.

My guess would be that a fully grown bull Trike would have relied on his nasal horn to do real damage)

The sweeping is not to deal major damage, its to keep it at bay as repetitive hits can cause soft tissue injuries and stunting the triceraptops, it can also lift it like fork lifter lol , and good luck stabbing with a short nasal horn while the triceratops its locked with a larger animal with longer tusks, the tusks can still stab the face while triceratops its still in a distance and even flip it, this would similiar to a white rhinoceros vs a african elephant.
