Half-Size, Ruffle-Headed Relative of Triceratops Discovered

If head frills were a style declaration, a recently determined 73- million-year-old triceratops relative was definitely at the top of its video game.

The newly found dinosaur called Crittendenceratops krzyzanowskii sported an elegant frill on the top of its head, a brand-new research study discovers. In reality, it’s the youngest-known dinosaur of its clade (the nasutoceratopsins), along with the very first of its clade on record to sport a fancy frill, the scientists stated.

” This clade has basic frills.” stated research study co-lead scientist Sebastian Dalman, who was at the New Mexico Museum of Nature and Science at the time of the research study. “ Crittendenceratops is the very first member of this clade with [an] ornamented frill.” [Tiny & Old: Images of ‘Triceratops’ Ancestors]

The late Stan Krzyzanowski, a research study partner at the New Mexico Museum of Nature and Science, found 2 of the late Cretaceous animals in the 1990 s in a range of mountains near Tucson, Arizona. Krzyzanowski and his coworkers quickly explained the dinosaur in a 2003 research study, however it wasn’t up until just recently that another appearance at the fossils exposed they represented an unknown types.

It was the monster’s special frill that exposed it was a newly found types, Dalman informed Live Science in an e-mail. The scientists called the dinosaur

‘s types name after Krzyzanowski, to honor this discovery.
The genus name ( Crittendenceratops )is originated from the Fort Crittenden Development, where the fossils were discovered. The suffix “ceratops” indicates “horned-face” in Greek.

Although C. krzyzanowskii is a relative of Triceratops(********** ), it was much smaller sized– about 11 feet( 3.3 meters) long, or less than half the size of its well-known cousin. Additionally, while Triceratops lived at the end of the dinosaur period, from about 67 million to 65 million years earlier, C. krzyzanowskii lived about 6 million years prior to that.

At that time C. krzyzanowskii lived by the banks of a fantastic lake in a forest of conifer and palm trees, stated research study co-lead scientist Spencer Lucas, a manager of paleontology at the New Mexico Museum of Nature and Science in Albuquerque. The fancy-frilled monster shared this location with mud turtles, alligators, duck-billed dinosaurs and even vicious tyrannosaurs.

Although Arizona is relatively dry now, it was a warm and damp subtropical location throughout the late Cretaceous. So the location used an abundant buffet for the 1,500- pound. (680 kgs) C. krzyzanowskii, which likely devoured on the area’s shrubs and conifers, Lucas stated.

The research study was released online in October in the New Mexico Museum of Nature and Science Publication
