Topic: Plesiosauria

  Palaeos Vertebrates 220.800  Lepidosauromorpha : Cryptocleidoidea
Perhaps a better name would be "Polycotyloidea." Be that as it may, we will again follow Cryptoclidoidea after O'Keefe, 2001 for the present.
The neck remains fairly short, similar in fact the early Jurassic plesiosaurs, and the tooth count in the lower jaw remains at 24 pairs (in the elasmosaurids it tends to be reduced), although tooth ornamentation is reduced or absent.
[2] from the Plesiosauria Translation and Pronunciation Guide: Cryptoclidus probably fed on schools of soft-bodied cephalopods and small fish, using its many teeth as a filter or trap--its lightly built skull and jaws were not designed to resist strong twisting forces generated by biting or tearing prey.

 The Plesiosaur Directory - Classification - Plesiosauria
The Plesiosauria has retained phylogenetic validity for well over 150 years, since the formal identification of the clade by de Blainville (1835).
The order Plesiosauria (plesiosaurs) consists of two superfamilies: the Pliosauroidea (often termed pliosaurs) (typically short-necked) and the Plesiosauroidea (often termed plesiosaurs but more accurately plesiosauroids) (long-necked).
The Plesiosauria is characterised by the presence of a suite of derived characters and extreme adaptations to life in the water.

 The Plesiosaur Directory - Palaeobiology - Feeding and senses
O'Keefe (2001) recently confirmed that the historical division of the order Plesiosauria into two superfamilies, plesiosauroids and pliosauroids, based on neck and head length alone, is wrong, although the division still stands based on other factors.
Phases of predation and evidence for each in the Plesiosauria: clearly, plesiosaurs were predators.
Fossils of carnivores in the act of predation are rare, and none are known for the Plesiosauria.

 Palaeos Vertebrates 220.400  Lepidosauromorpha: Plesiosauria
The Pistosaurs were morphologically intermediate between nothosaurs and the Plesiosauria proper.
In Linnean systematics, it is variously classified under the Nothosauridae and the Plesiosauria, depending on what characteristics one uses to define membership of each group.
The Plesiosauria (the name means "near lizards,") were an important order of Mesozoic marine reptiles, members of the superorder Sauropterygia.

Plesiosaurs Prehistoric Animals Plesiosaurs Pictures catalog extinct extinction endangered Plesiosaurs are an extinct group of large aquatic reptiles that ranged through the oceans of the world from the late Triassic until the end of the Cretaceous, or from about 195 million to 65 million years ago.
The plesiosaurs make up the suborder Plesiosauria in the order Sauropterygia and are usually divided into the superfamilies Plesiosauroidea, or long-necked plesiosaurs, and the Pliosauroidea, or short-necked plesiosaurs.
The number of neck bones, or vertebrae, in these differing forms varied from as few as 13 in Brachauchenius to 76 in Elasmosaurus, whose neck was twice as long as its body.

Among the Plesiosauria, the proportions of the trunk and limbs remains relatively constant.
On the other hand, the proportions of skull and neck vary greatly, and serve as the most obvious feature which further divides the order into its two constituent groups: the long-necked and short-skulled plesiosaurs (including the elasmosaurs), and the short-necked and long-skulled pliosaurs.

 Dinosaur Myths and Misinformation
One of the larger Mesozoic animals was a euryapsid reptile, the pliosaur Liopleurodon (Class Reptilia, Subclass Sauropterygia, Order Plesiosauria, Superfamily Plesiosauroidea), of BBC "Walking with Dinosaurs" fame.
There is also detailed discussion of the methods used to determine the size of these giant animals, how we can date the fossils and describe their living environments, and why we can be sure who at whom 80 million years ago.
The Sauropterygia were marine predators of the Mesozoic, which includes the Triassic near shore orders, Nothosauria and Pachypleurosauria, and the post-Triassic, fully marine, Plesiosauria which comprises the short-necked pliosaurs and the longer-necked plesiosaurs.
