The stage takes its name from the town of Semur-en-Brionnais, near Sancerre in the upper Loire Valley. The calcareous soil formed from the Jurassic limestone of the region is in part responsible for the character of the classic Sancerre wines.
In Europe this period, together with the Hettangian, is also known as the Lower (or Blue) Lias Stage.
|Ichthyosauria of the Sinemurian|
|From Hettangian to Sinemurian||Belgium, England, Germany||Among the best known ichthyosaur genera, was smaller than most of its relatives, measuring 2 m (6 ft 8 inches) in length.|
|Ornithischians of the Sinemurian|
|From Hettangian to Sinemurian||Upper Elliot Formation, Lesotho and Cape Province, South Africa||Considered the most basal member of the family Heterodontosauridae|
|From Hettangian to Sinemurian||Lesotho||As the only fossil known of it is a partial jawbone with three teeth, Fabrosaurus is a nomen dubium and may in fact be the same as Lesothosaurus.|
|Clarence Formation, Cape Province, South Africa||With few remains, it is considered a nomen dubium. It is classified as an ornithischian based on the jaw.|
|From Hettangian to Sinemurian||Upper Elliot Formation, Orange Free State, South Africa||A heterodontosaurid ornithischian|
|Dated disputed||Unknown location in Portugal||Only known from a partial snout with teeth|
|From Hettangian to Sinemurian||Upper Elliot Formation, Cape Province, South Africa||A small herbivore dinosaur despite long canines it sported in its jaws; due to this unique characteristic it is very clearly allied to Heterodontosaurus|
|England||Disputed, considered by some to be a tetanuran theropod|
|From Hettangian to Sinemurian||Charmouth, West Dorset, England; Kayenta Formation, Arizona, USA||A genus of quadrupedal, lightly plated, herbivorous dinosaur about 4 meters long (13 ft)|
|From Hettangian to Sinemurian||Stormberg Series Formations, South Africa, Lesotho||A primitive ornithischian, about 2 meters long. The proportions of the posterior limbs show differences with those of Lesothosaurus, and reveal a lower ability to run|
|Plesiosauria of the Sinemurian|
|Granby, Leicestershire, England||May have been a rhomaleosaurid, pliosaurid or elasmosaurid|
| ||Sinemurian and Toarcian||Lyme Regis, Dorset, England||A large (about 3 to 5 meters long), marine sauropterygian reptile, it was distinguished by its small head, long and slender neck, broad turtle like body, a short tail, and two pairs of large, elongated paddles|
