  Volcanic Blast Likely Killed and Preserved Juvenile Fossil Plesiosaur Found in Antarctica
The long-necked, diamond-finned plesiosaurs are probably most familiar as the legendary inhabitants of Scotland's Loch Ness, although scientific evidence indicates the marine carnivores have been extinct for millions of years.
Whether plesiosaurs gave live birth has not been proved, but numerous bones and partial skeletons of larger plesiosaurs were found in the same area as the young.
That plesiosaur was named Mauisaurus and is characterized by a rounded end of the major paddle bone.

 The Plesiosaur Directory - Palaeobiology - Locomotion
Robinson (1975) uses many lines of evidence to dispel the notion that plesiosaurs were exclusively rowing animals, the most convincing points being the paddle shape and the joint between propodials (humerus and femor) and the girdles (pelvic and pectoral) both of which facilitate a rowing method.
However, small plesiosaurs may have been relatively uneffected by such constraints and it is not unreasonable to imagine them using their powerful limb downstrokes to propel them forward in short 'hops'.
Plesiosaurs overcome this problem in the same way is the contemporaneous Ichthyosaurs and evolved the ability to give birth to live young.

 Plesiosaur - CreationWiki
The Plesiosaur is an extinct marine reptile that is found in strata identified as the Mesozoic, Jurassic, and Cretaceous Eras.
The Plesiosaur was known to have probably very little trouble maneuvering its way around in the water and has quicksilver reactions or reflexes and speed as fast as lightning.
The Plesiosaurs would eat ballasts so it would help pulverize food in their stomach so that digestion was not so problematical and to help them dive deep in the water to the beyond.

The common name 'plesiosaur' is applied both to the 'true' plesiosaurs (Suborder Plesiosauroidea) and to the larger taxonomic rank of Plesiosauria, which includes both long-necked (elasmosaurs) and short-necked (polycotylid) forms.
The first plesiosaur skeletons were found in England by Mary Anning, in the early 1800s, and were amongst the first fossil vertebrates to be described by science.
While the survival of a small, unrecorded breeding colony of plesiosaurs for the 65,000,000 years since their apparent extinction is unlikely, the discovery of real and even more ancient living fossils such as the Coelacanth and of previously unknown but enormous deep-sea animals such as the giant squid, have fuelled imaginations.

Plesiosaur teeth have a conical indent in the bottom of the root to fit into the socket of the jaw.
The scrappy reptilian bone of mosasaurs, sea turtles, "crocodiles", and plesiosaurs are similar and are all found at this locality.
This may suggest the more ancient plesiosaurs, that where around since the Jurassic, were becoming out classed by the newer types of mosasaurs, modern types of crocodiles, and sharks.

 Why the Loch Ness Monster is no plesiosaur - life - 02 November 2006 - New Scientist
The plesiosaur, a marine reptile that lived 160 million years ago, looked like nothing alive today, with a neck that was some 2 metres long, the length of the body and tail combined.
Plesiosaurs used their long necks to reach down and feed on soft-bodied animals living on the sea floor, Noè told the Society of Vertebrate Paleontology meeting in Ottawa, Canada, last month.
He examined fossils of a plesiosaur called Muraenosaurus, and by calculating the articulation of the neck bones he concluded the neck was flexible and could move most easily when pointing down.

 Sea-Monster or Shark: An Alleged Plesiosaur Carcass
Nevertheless, the discovery of a modern plesiosaur would certainly be a stupendous scientific find in its own right, confirming that long-necked "sea serpents" were not just long-extinct creatures or the stuff of sailor's myths, but real "living fossils." Unfortunately, a more thorough examination of the evidence would convincingly refute the plesiosaur interpretation.
In many plesiosaurs the neck is by the longest section, and in no case is the torso (between the pelvic and pectoral fins) much longer than the head and neck, as it is in the carcass.
If the creature were a plesiosaur, it would have had to be a short necked plesiosaur, whose ribs would be at least triple the reported length (John Martin 1997).

 Plesiosaur - Conservapedia
Plesiosaurs are large reptiles characterized by long necks with small heads; stocky, finless tails; and a broad, turtle-like body with four flippered appendages.
The name plesiosaur (or plesiosaurus) comes from the Greek for "near to lizard", and was named by William Conybeare to signify that it was more lizard-like than the fish-like ichthyosaurus, which was first found only a few years previously nearby.
The most often cited evidences for this theory are the many modern sightings around the globe of creatures that fit the description of a plesiosaur, the most famous of which have been reported at Loch Ness, Scotland (the so-called "Loch Ness Monster" or "Nessie") and Lake Okanagan in British Columbia (known as "Ogopogo").

The past existence of plesiosaurs is evident from the wealth of fossilized skeletal remains unearthed worldwide.

It is also believed that plesiosaurs crawled on to beaches to lay their eggs in a similar manner to turtles, the rigid base providing the necessary support and protection.

 The Plesiosaur Directory - Classification - Plesiosauria   (Site not responding. Last check: )
Plesiosaurs are a secondarily aquatic group of carnivorous reptiles belonging to the clade Sauropterygia within the diapsid clade Euryapsida (Tayor, 1989; Caldwell, 1997).
The family Polycotylidae for example is a Late Cretaceous group of short-necked plesiosaurs, but cranial evidence (Carpenter, 1997) points to plesiosauroid affinity rather than pliosaur, despite the short necks.
Ambiguous plesiosaur material occurs in Middle Triassic deposits (Benton, 1993) but the first diagnostic plesiosaurs are uppermost Triassic in age (Taylor and Cruickshank, 1993b; Storrs, 1994, 1997).
