Sierraceratops

Sierraceratops (meaning "Sierra horned face") is a genus of chasmosaurine ceratopsian from the Late Cretaceous Hall Lake Formation of New Mexico, United States. The genus contains a single species, Sierraceratops turneri, known from a partial skeleton discovered in 1997.

==Discovery== In 1997, geologist Gregory H. Mack discovered fossils of a large horned dinosaur on the Armendaris ranch of Ted Turner, founder of CNN, near Truth or Consequences in Sierra County, New Mexico. They had been exposed on the surface by erosion. A team of the New Mexico Museum of Natural History and Science subsequently uncovered more bones with the cooperation of the ranch manager, Tom Wadell. In 1998, the discovery was reported in the scientific literature and referred to Torosaurus latus. More fossils were collected in 2014, 2015, and 2016. They were first prepared by volunteers and later by Sebastian Dalman.
