Einiosaurus procurvicornis Dinosaur skull

Einiosaurus procurvicornis (hooked nose horn). This is a very rare Einiosaurus procurvicornis (some spell: Einosaurus procurvicornus) (Einiosaurus) skull with all 3 horns.

This is a fairly new discovery (1985) it was named in 1995 and is called "buffalo lizard". It is a medium-sized centrosaurine (short-frilled) ceratopsian from the Upper Cretaceous. Compared to Triceratops, the Einiosaurus had a short-frill.

Einosaurus was a herbivore. Though a sub adult, this Einosaur would have grown to about 20 ft long.

Geological Formation: Two Medicine Formation

Location: Discovered 2 miles from the Canadian border north of Dupuyer, Montana NW Montana.

This is a very rare dinosaur skull. Very few have been discovered. This skull is the complete upper skull with braincase. It is missing some frill behind dinosaur's right eye and also the lower jaw. The skull itself has no restoration (only crack filling). The nose horn measures 23 inches. The nose curves downward like a can-opener.

Einiosaurus had 2 horns off the frill. Though not attached, this skull comes with two horns. One of these was discovered with the skull, the 2nd comes from a slightly larger member of the same dinosaur. It is a good match for size. These horns are not connected to the skull but can be with a little restoration.

We have seen reconstructed skulls of this dinosaur go for $50,000 to $60,000 while still in the ground!

Photo above is for comparison only. This is a Einiosaurus procurvicornis skull that was recently up for auction. You can compare it to the pictures on the left (and below) and you will see how nicely this skull will look with a little restoration.

Legally collected, this skull comes with pictures, and details of the discovery. It was found in a ravine with a herd that died from a sudden flood. It is one of most unusual dinosaurs that ever lived and it may have gone extinct due to the horn pointing down (and not being able to use it for defense).

Few remains have been found of this animal and most museums do not have any remains of this animal. There are very few people who have this is private collections - so your purchase will make you among the most rare of museums or collectors.

This sub-adult skull measures 44". This is an opportunity to get a great skull for an economical price. I fell in love with this dinosaur the second I saw it. It is just beautiful. Displays well on top of a table or any piece of furniture and can safely be carried by two people. I can't say enough about this dinosaur. It is beyond words. Call for more details on this one.

Einiosaurus is a medium-sized centrosaurine (“short-frilled”) ceratopsian from the Upper Cretaceous (Campanian) Two Medicine Formation of northwestern Montana. The generic epithet means 'buffalo lizard', in a combination of Blackfeet Indian and Latinized Ancient Greek and the specific epithet means 'forward-curving horn' in Latin and Ancient Greek.

Fossil Material Einiosaurus is an exclusively Montanan dinosaur, and all its known remains are currently held at the Museum of the Rockies in Bozeman, Montana. At least 15 individuals of varying ages are represented by three adult skulls and hundreds of other bones from two low-diversity (in species) bonebeds, which were discovered by Jack Horner in 1985 and excavated from 1985 - 1989 by Museum of the Rockies field crews. These bonebeds were originally thought to contain a new species of Styracosaurus and are referred to as such in the comprehensive taphonomic study by Ray Rogers (1990).

Description In 1995 Scott D. Sampson formally described and named Einiosaurus procurvicornis from this material, as well as Achelousaurus horneri, also from a bonebed in this region. Einiosaurus is typically portrayed with a low, strongly forward-curving nasal horn that resembles a bottle opener, though this may only occur in some adults. Supraorbital (over-the-eye) horns are low and rounded if present at all, as opposed to ceratopsids with prominent supraorbital horns such as Triceratops. A pair of large spikes projects

Taphonomy and paleobiology Low-diversity and monospecific bonebeds are thought to represent herds that may have died catastrophically, such as during a drought or flood. This is evidence that Einiosaurus, as well as other centrosaurine ceratopsians such as Pachyrhinosaurus and Centrosaurus, were gregarious, herding animals similar in behavior to modern-day bison or wildebeest. In contrast, chasmosaurine (“long-frilled”) ceratopsids, such as Triceratops and Torosaurus, are typically found singly, implying that they may have been somewhat solitary in life, though fossilized footprints may provide evidence for the contrary.

Einiosaurus was a herbivorous dinosaur and grew to 6 meters in length. Like all ceratopsids, it had a complex dental battery capable of processing even the toughest plants. Contemporaneous dinosaurs include the basal ornithopod Orodromeus, the hadrosaurids Hypacrosaurus, Maiasaura, and Prosaurolophus; ankylosaurs Edmontonia and Euoplocephalus, the tyrannosaurid Daspletosaurus (which appears to have been a specialist of preying on ceratopsians), as well as the smaller theropods Bambiraptor, Chirostenotes, Troodon, and Avisaurus; and the ceratopsids Brachyceratops and Achelosaurus. Einiosaurus lived in a climate that was seasonal, warm, and semi-arid. Other fossils found with the Einiosaurus material include freshwater bivalves and gastropods, which imply that these bones were deposited in a shallow lake environment.

Phylogeny The placement of Einiosaurus within Centrosaurinae is problematic due to the transformational nature of several of its skull characters, and its closest relatives are either Centrosaurus and Styracosaurus or Achelousaurus and Pachyrhinosaurus. The latter hypothesis is supported by Horner et al. (1992), where Einiosaurus is the earliest of a transformational series in which the nasal horns gradually change to rugose bosses, as in Achelousaurus and Pachyrhinosaurus who are the second and third in this series. The frills also grow in complexity.

Regardless of which hypothesis is correct, Einiosaurus appears to occupy an intermediate position with respect to the evolution of the centrosaurines.
