Synapsida[a] is a diverse group of tetrapod vertebrates that includes all mammals and their extinct relatives. It is one of the two major clades of the group Amniota, the other being the more diverse group Sauropsida (which includes all extant reptiles and, therefore, birds). Unlike other amniotes, synapsids have a single temporal fenestra, an opening low in the skull roof behind each eye socket, leaving a bony arch beneath each; this accounts for the name “synapsid”.[8] “}}

Archosauria or archosaurs (/ˈɑːrkəˌsɔːr/[3]) is a clade of diapsid sauropsid tetrapods, with birds and crocodilians being the only known extant representatives. Although broadly classified as reptiles, which traditionally exclude birds, the cladistic sense of the term includes all living and extinct relatives of birds and crocodilians such as non-avian dinosaurs, pterosaurs, phytosaurs, aetosaurs and
rauisuchians as well as many Mesozoic marine reptiles. Modern paleontologists define Archosauria as a crown group that includes the most recent common ancestor of living birds and crocodilians, and all of its descendants.

The basalt cliffs are the margin of a diabase sill, formed about 200 million years ago,[3] at the close of the Triassic period, by the intrusion of molten magma upward into sandstone.[4] The molten material cooled and solidified before reaching the surface. Water erosion of the softer sandstone left behind the columnar structure of harder rock that exists today. The cliffs are about 300 ft (100 m) thick in sections and originally may have reached 1,000 ft (300 m). “}}

QT:{{”
Triceratops (/traɪˈsɛrətɒps/ try-SERR-ə-tops;[3] lit. ’three-horned face’) is a genus of chasmosaurine ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous period, about 68 to 66 million years ago on the island continent of Laramidia,[1][2] now forming western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous–Paleogene extinction event 66 million years ago. The name Triceratops, which means ‘three-horned face’, is derived from the Ancient Greek words τρί- (trí-), meaning “three”, κέρας (kéras), meaning “horn”, and ὤψ (ṓps), meaning “face”.

Bearing a large bony frill, three horns on the skull, and a large, four-legged body, exhibiting convergent evolution with rhinoceroses, Triceratops is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around 8–9 m (26–30 ft) long and weighing up to 6–10 t (5.9–9.8 long tons; 6.6–11.0 short tons). It shared the landscape with and was most likely preyed upon by Tyrannosaurus.

Triceratops was a herbivore, munching on tough, low-lying plants like ferns, cycads, palms, and shrubs, using its sharp beak to snip them and its powerful dental batteries (hundreds of teeth) to grind fibrous material. These large dinosaurs needed to eat massive amounts daily, potentially using their horns and bulk to knock over taller trees or bushes for easier access to food, as grasses hadn’t evolved yet. “}}

Edmontosaurus (/ɛdˌmɒntəˈsɔːrəs/ ed-MON-tə-SOR-əs) (meaning “lizard from Edmonton”), often colloquially and historically known as Anatosaurus or Anatotitan (meaning “duck lizard” and “giant duck”), is a genus of hadrosaurid (duck-billed) dinosaur.

Allosaurus, Tyrannosaurus (T-Rex), and Carcharodontosaurus are all large, iconic predatory dinosaurs (theropods) but lived in different times and places: Allosaurus was a Late Jurassic giant from North America/Europe, T. rex ruled Late Cretaceous North America, and Carcharodontosaurus was a massive, “shark-toothed” predator of Mid-Cretaceous North Africa, often rivaling T-Rex in size but belonging to a different evolutionary branch (Carcharodontosauridae). They represent different predatory “eras,” with
Carcharodontosaurids…
