Titanoceratops ouranos
Titanoceratops (meaning "titanic horn face") is a genus of herbivorous ceratopsian dinosaur. It was a giant chasmosaurine ceratopsian which lived during the Late Cretaceous period (late Campanian, 74.5–73.7 Ma) in what is now New Mexico, and the earliest known triceratopsin. It is known solely from the holotype OMNH 10165, a partial skeleton including partial skull and jaws. The holotype is thought to come from the upper Fruitland Formation or the lower Kirtland Formation based on field notes and the lithology of the matrix surrounding the fossils, but unfortunately the precise location of the quarry is no longer known. The species was formally named by Nicholas R. Longrich in 2011 and the type species is Titanoceratops ouranos. Previously, its fossils were assigned to Pentaceratops. The skull is estimated to be 2.65 m (8.7 ft) long when complete, making it a candidate for the longest skull of any terrestrial vertebrate. It would have been at least 6.8 meters long (22.3 ft) and at least 6.5 tons in weight. Tom Holtz (2010) noted that it is extremely similar to its closely related contemporaries Eotriceratops and Ojoceratops, which may all be synonymous.
Dacentrurus armatus
Dacentrurus (meaning "tail full of points"), originally known as Omosaurus, was a large stegosaur of the Late Jurassic Period (154 - 150 mya) of Europe. Its type species, Omosaurus armatus, was named in 1875, based on a skeleton found in the Kimmeridge Clay of England. In 1902 the genus was renamed Dacentrurus because the name Omosaurus had already been used for a crocodylian. After 1875, half a dozen other species would be named but perhaps only Dacentrurus armatus is valid. Finds of this animal have been limited and much of its appearance is uncertain. It was a heavily built quadrupedal herbivore, adorned with plates and spikes. Dacentrurus was a large stegosaurid. Some specimens reached lengths 10 meters (33 ft) and weighed 8 t (8.8 short tons). Many books claim that Dacentrurus was a small stegosaur, when in fact finds such as a 1.5 metres (4.9 ft) wide pelvis indicate that Dacentrurus was among the largest of them. For a stegosaur the gut was especially broad, and a massive rump is also indicated by exceptionally wide dorsal vertebrae centra. The hindlimb was rather short, but the forelimb relatively long, largely because of a long lower arm. Although Dacentrurus is considered to have the same proportions as Stegosaurus, its plate and spike configuration is known to be rather different, as it probably had both two rows of small plates on its neck and two rows of longer spikes along its tail. The holotype specimen of Dacentrurus armatus contained a small blunt asymmetrical neck plate and also included a tail spike which could have been part of a thagomizer. The tail spike had sharp cutting edges on its front and rear side. Dacentrurus has sometimes been portrayed with a spike growing near the shoulder, similarly to a Kentrosaurus. Whether this portrayal is accurate or not is not yet determined.
