Plesiosauroidea (/ ˈ p l iː s i ə s ɔːr /; Greek: πλησιος plēsios 'near, close to' and σαυρος sauros 'lizard') is an extinct clade of carnivorous marine reptiles.They have the snake-like longest neck to body ratio of any reptile. Plesiosauroids are known from the Jurassic and Cretaceous periods.After their discovery, some plesiosauroids were said to have …The Pierre Shale is a dark gray to black shale that covers much of the High Plains and extends from southern Colorado to central North Dakota. The Sharon Springs Member is a uraniferous organic member of the Pierre (Gautier and others, 1984). Landis3. Orientation of the Pierre Shale along the Front Range -Beds have a nearly vertical alignment where uplifted along the Front Range. -This creates a 1.5-3.2 km wide band along the Front Range. -A dip angle of 30° or greater leads to the particular case of heaving bedrock Many beds intersect the ground surface each with different swell potentials.
