Illustration of specimen YPM 1871E, the horn cores that were erroneously attributed to Bison alticornis, the first named specimen of Triceratops. The first named fossil specimen now attributed to Triceratops is a pair of brow horns attached to a skull roof that were found by George Lyman Cannon near Denver, Colorado, in the spring of 1887. [3]
Later members, including ceratopsids like Centrosaurus and Triceratops, became very large quadrupeds and developed elaborate facial horns and frills extending over the neck. While these frills might have served to protect the vulnerable neck from predators , they may also have been used for display , thermoregulation , the attachment of large ...
The horns above the eyes were forward-curving and have been estimated at 80 cm (2.6 ft) long. The lower base of these horns was narrow and vertically directed, which with Triceratops is a juvenile trait. Three bite marks can be observed above the eye, near the base of the left horn, which were interpreted as traces of scavenging.
Named partly for the Norse god of mischief, Lokiceratops rangiformis was a cousin of Triceratops and lived in a swampy environment alongside other horned dinosaur species about 78 million years ago.
A previously unknown species of dinosaur finally has a name five years after the horned specimen’s discovery in Montana: Lokiceratops rangiformis.
He observed that Triceratops is one of the most common dinosaurs in the fossil record. [28] Dodson and Currie performed a cladistic analysis of the ceratopsids found further support for regarding Triceratops as a "long-frilled" ceratopsid. [12] Lehman supported Ostrom and Wellnhofer's conclusion that there was only one valid species of ...
The remains of a brow horn suggested that the fossil was a large Triceratops, [3] one of the most common dinosaurs found in the Hell Creek Formation. [4] The remains were scattered over an area of 100 square metres. [5] The fossil's excavation was completed by August 2015. [6] The skeleton is over 60% complete, with a skull that is 75% complete ...
