The Pliensbachian is an age of the geologic timescale or stage in the stratigraphic column. It is part of the Early or Lower Jurassic epoch or series and spans the time between 190.8 ± 1.5 Ma and 182.7 ± 1.5 Ma (million years ago). The Pliensbachian is preceded by the Sinemurian and followed by the Toarcian.
The Pliensbachian ended with the extinction event called the Toarcian turnover. During the Pliensbachian, the middle part of the Lias was deposited in Europe. The Pliensbachian is roughly coeval with the Charmouthian regional stage of North America.
The Pliensbachian takes its name from the hamlet of Pliensbach in the community of Zell unter Aichelberg in the Swabian Alb, some 30 km east of Stuttgart in Germany. The name was introduced into scientific literature by German palaeontologist Albert Oppel in 1858.
The base of the Pliensbachian is at the first appearances of the ammonite species Bifericeras donovani and genera Apoderoceras and Gleviceras. The Wine Haven profile near Robin Hood's Bay (Yorkshire, England) has been appointed as global reference profile for the base (GSSP).

""Podokesaurus"" was a small carnivorous dinosaur that living during the Pliensbachian–Toarcian stages of the Early Jurassic Period, and as such is one of the earliest known dinosaurs to inhabit the eastern United States. The generic name "Podokesaurus" is derived from Greek word "podōkēs" meaning "swift-footed", an epitheton often used by Homer in the Iliad to describe the hero Achilles, and "saura" meaning "lizard"; thus "swift-footed lizard". The specific name refers to Holyoke, a city in Massachusetts, in the Connecticut River Valley. The type specimen suggests that "Podokesaurus" was a small, bipedal carnivore was about 90 cm long and 0.3 m tall. Its upper leg bone measures 86 mm in length, and its lower leg bone measures 104 mm in length. The tibia and other skel...
""Scelidosaurus"" is a genus of herbivorous armoured ornithischian dinosaur from the Jurassic of England. "Scelidosaurus" lived during the Early Jurassic Period, during the Sinemurian to Pliensbachian stages around 191 million years ago. This genus and related genera at the time lived on the supercontinent Laurasia. Its fossils have been found near Charmouth in Dorset, England, and are known for their excellent preservation. "Scelidosaurus" has been called the earliest complete dinosaur. It is the most completely known dinosaur of the British Isles. Despite this, a modern description is still lacking. After initial finds in the 1850s, comparative anatomist Richard Owen named and described "Scelidosaurus" in 1859. Only one species, "Scelidosaurus harrisonii" named by Owen in 1861, is c...
""Anchisaurus"" is a genus of basal sauropodomorph. An early herbivorous dinosaur, lived during the Early Jurassic Period; more specifically, the Pliensbachian to Toarcian ages, 190 to 174 million years ago. Until recently it was classed as a member of Prosauropoda. The name comes from the Greek "αγχι"/"agkhi" anchi-; "near, close" + Greek "σαυρος"/"sauros"; "lizard", probably referring to Marsh's interpretation of it as intermediate between primitive dinosaurs and more derived dinosaurs. "Anchisaurus" was coined as a replacement name for "Amphisaurus", which was itself a replacement name for Hitchcock's "Megadactylus", both of which had already been used for other animals. Hitchcock collected these bones under the name "Megadactylus" in 1865. However, the name was already in use, and...
Cryolophosaurus (pronounced /ˌkraɪ.ɵˌlɒfɵˈsɔːrəs/ or /kraɪˌɒlɵfəˈsɔːrəs/, meaning "cold crest lizard") was a large theropod dinosaur, with a bizarre crest on its head that looked like a Spanish comb. Due to the resemblance of this feature to Elvis Presley's pompadour haircut from the 1950s, this dinosaur was at one point informally known as "Elvisaurus". Cryolophosaurus was excavated from Antarctica's Early Jurassic (Pliensbachian stage) Hanson Formation (former the upper Falla Formation) by paleontologist Dr. William Hammer in 1991. It is the first carnivorous dinosaur to be discovered in Antarctica and the first dinosaur of any kind from the continent to be officially named. Dating from the Early Jurassic Period, it was originally described as the earliest known tetanuran, though subs...
What is JURASSIC? What does JURASSIC mean? JURASSIC meaning, definition & explanation. The Jurassic is a geologic period and system that extends from 201.3 Mya (million years ago) to 145.5 Mya; from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. The start of the period is marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Pliensbachian/Toarcian event in the Early Jurassic, and the Tithonian event at the end; however, neither event ranks among the "Big Five" mass extinctions. The Jurassic is named after the Jura Mountains within the European Alps, where limestone strata from the period were first identified. By the...
""Cryolophosaurus"" is a genus of large theropods known from only a single species ""Cryolophosaurus ellioti"", known from the early Jurassic period of Antarctica. It was about 6.5 m long and 465 kg in weight, making it one of the largest theropods of its time. Individuals of this species may have grown even larger, because the only known specimen probably represents a sub-adult. "Cryolophosaurus" is known from a skull, a femur and other material, the skull and femur of which have caused its classification to vary greatly. The femur possesses many primitive characteristics that have classified "Cryolophosaurus" as a dilophosaurid or a neotheropod outside of Dilophosauridae and Averostra, where as the skull has many advanced features, leading the genus to be considered a tetanuran, an abe...
The Jurassic (/dʒuːˈræsɪk/; from Jura Mountains) is a geologic period and system that extends from 201.3± 0.6 Ma (million years ago) to 145± 4 Ma; from the end of the Triassic to the beginning of the Cretaceous. The Jurassic constitutes the middle period of the Mesozoic Era, also known as the Age of Reptiles. The start of the period is marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Late Pliensbachian/Early Toarcian event in the Early Jurassic, and the Late Tithonian event at the end; however, neither event ranks among the "Big Five" mass extinctions. The Jurassic is named after the Jura Mountains within the European Alps, where limestone strata from the period were first identified. By the beginning of the Jurassic, the s...
This is a tribute to Cryolophosaurus also known as the Elvis Presley Dino. here is some info on Cryolophosaurus. Cryolophosaurus (/ˌkraɪ.ɵˌlɒfɵˈsɔrəs/ or /kraɪˌɒlɵfəˈsɔrəs/; "CRY-oh-loaf-oh-SAWR-us") was a large theropod dinosaur, with a crest on its head that looked like a Spanish comb. Due to the resemblance of this feature to Elvis Presley's pompadour haircut from the 1950s, this dinosaur was at one point informally known as "Elvisaurus". Cryolophosaurus was excavated from Antarctica's Early Jurassic (Pliensbachian stage) Hanson Formation (formerly the upper Falla Formation) by paleontologist Dr. William Hammer in 1991. It is the first carnivorous dinosaur to be discovered in Antarctica and the first non-avian dinosaur from the continent to be officially named. Dated at 190 million ye...
