Titanoceratops
''Titanoceratops'' (meaning "titanic horned face") is a controversial genus of herbivorous ceratopsian dinosaur. It was a giant chasmosaurine ceratopsian that lived in the Late Cretaceous period (Campanian stage, about 75 million years agoFowler, D. W. 2017. Revised geochronology, correlation, and dinosaur stratigraphic ranges of the Santonian-Maastrichtian (Late Cretaceous) formations of the Western Interior of North America.

''Titanoceratops'' was named for its large size, being one of the largest known horned dinosaurs and the type species was named ''T. ouranos'', after Uranus (Ouranos), the father of the Greek titans. It was named in 2011 by Nicholas R. Longrich for a specimen previously referred to '' Pentaceratops''. Longrich believed that unique features found in the skull reveal it to have been a close relative of ''Triceratops'', classified within the subgroup Triceratopsini.

Triceratopsini
Triceratopsini is a tribe of herbivorous chasmosaurine dinosaurs that lived between the late Campanian to the late Maastrichtian stages of the Cretaceous period, between 74.73 and 66 million years ago. Fossils of these animals have been found in western North America, in particular West Canada, Western and Midwestern United States, which was once part of the ancient continent of Laramidia. The tribe was named by Nicholas R. Longrich in 2011 for the description of ''Titanoceratops'', which he defined as "all species closer to ''Triceratops horridus'' than to ''Anchiceratops ornatus'' or '' Arrhinoceratops brachyops''". Triceratopsins were the largest of the chasmosaurines; suggesting that gigantism had evolved in the Ceratopsidae once. In addition there is an evolutionary trend in the solidification of the frills, the most extreme being in ''Triceratops''. Systematics The tribe was named by Nicholas R. Longrich in 2011 for the description of ''Titanoceratops'', which he defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentaceratops
''Pentaceratops'' ("five-horned face") is a genus of herbivorous ceratopsid dinosaur from the late Cretaceous Period of what is now North America. Fossils of this animal were first discovered in 1921, but the genus was named in 1923 when its type species, ''Pentaceratops sternbergii'', was described. ''Pentaceratops'' lived around 76–73 million years ago, its remains having been mostly found in the Kirtland Formation in the San Juan Basin in New Mexico. About a dozen skulls and skeletons have been uncovered, so anatomical understanding of ''Pentaceratops'' is fairly complete. One exceptionally large specimen later became its own genus, ''Titanoceratops'', due to its more derived morphology, similarities to ''Triceratops,'' and lack of unique characteristics shared with ''Pentaceratops''. ''Pentaceratops'' was about 6 meters (20 feet) long, and has been estimated to have weighed around . It had a short nose horn, two long brow horns, and long horns on the jugal bones. Its skul ...

Kirtland Formation
The Kirtland Formation (originally the Kirtland Shale) is a sedimentary geological formation. Description The Kirtland Formation is the product of alluvial muds and overbank sand deposits from the many channels draining the coastal plain that existed on the inland seashore of North America, in the late Cretaceous period. It overlies the Fruitland Formation. It is found in the San Juan Basin in the states of New Mexico and Colorado, in the United States of America. The base of the Kirtland Formation and its lowest sub-unit, the Hunter Wash member, has been dated to 75.02 ± 0.13 Ma. Together with the upper part of the underlying Fruitland Formation, this contains fossils representing the Hunter Wash local fauna. The border between the Hunter Wash member and overlying Farmington member dates to approximately 74 million years ago. The top of the Farmington member and bottom of the overlying De-na-zin member has been radiometrically dated to 73.83 ± 0.18 Ma ago. The to ...
