Utahceratops gettyi 的頭骨有2.3米長，鼻部上方有一個大角，兩側有顯著的短而鈍的眼角，因為角不是朝上的關係，相較於三角龍則更像是現代野牛。
Kosmoceratops richardsoni 共有15支角，1支在鼻部、每隻眼睛上方以及顴骨上方各1支角、沿著後方骨狀皺褶共有10支角，這些角使得它成為已知最華麗的恐龍。
這個發現地點，被稱為Suarez Sister's Site，是位在綠河附近由土地管理局的土地上。此處還以恐龍大規模死亡的第二地點聞名，這些恐龍還包括奇特的鐮刀爪恐龍 Falcarius。
A record breaking eight new species of dinosaur were described from federal public lands in Utah in 2010 - each representing a genus that is new to science.
On December 15, the Bureau of Land Management, Utah Geological Survey, and Temple University announced the naming of the seventh new dinosaur discovered on BLM lands in Utah this year.
The small Geminiraptor suarezarum, found on BLM lands near Green River, Utah, is the oldest reported "raptor-like" troodontid dinosaur in North America - 125 million years old. Most troodontid dinosaurs from North America are dated to between 72 and 75 million years ago.
Additionally, the National Park Service named a new long-necked dinosaur to bring the state of Utah to a record-breaking total of eight new dinosaurs in 2010.
Worldwide there about 700 named dinosaurs. This string of dinosaur descriptions means that one percent of all known dinosaur species were described from lands in Utah during 2010.
Troodontid dinosaurs like Geminiraptor suarezarum are "raptor-like" dinosaurs often credited with being more intellectually advanced based on their large cranial capacity compared with the overall size of the animal.
Close relatives of the famous Triceratops, the recently discovered plant-eating Utahceratops and Kosmoceratops found on Bureau of Land Management lands in Utah received their names in 2010.
Utahceratops gettyi has a skull 2.3 meters long, a large horn over the nose, and short and blunt eye horns that project strongly to the side rather than upward, much more like the horns of modern bison than those of Triceratops.
Kosmoceratops richardsoni has a total of 15 horns - one over the nose, one atop each eye, one at the tip of each cheek bone, and ten across the rear margin of the bony frill - making it the most ornate headed dinosaur known.
Geminiraptor, at about 125 million years of age, is easily the oldest. The specimen, housed at the College of Eastern Utah Prehistoric Museum, is a distinctive, but incomplete upper jaw inflated by a large, unique air sack that identifies the fossil as belonging to a new species of troodontid.
The site where it was found, known as the Suarez Sister's Site, is located on BLM lands near Green River and is the second area that is known to have a mass-mortality assemblage of dinosaurs that include the odd sickle-clawed dinosaur Falcarius.
The discovery was part of a project on BLM lands funded by the Discovery Channel and the Utah Geological Survey and was featured on the 2005 Science Channel documentary "Utah's Dinosaur Graveyard."
