Pliosauroidea is an extinct clade of plesiosaurs, known from the earliest Jurassic to early Late Cretaceous.They are best known for the subclade Thalassophonea, which contained crocodile-like short-necked forms with large heads and massive toothed jaws, commonly known as pliosaurs.
Pliosaurus (meaning 'more lizard') is an extinct genus of thalassophonean pliosaurid known from the Late Jurassic (Kimmeridgian and Tithonian stages) of Europe and South America. This genus has contained many species in the past but recent reviews found only six ( P. brachydeirus ( type species ), P. carpenteri , P. funkei , P. kevani , P ...
Some plesiosaurian remains, such as a 2.875-metre-long (9.43 ft) set of highly reconstructed and fragmentary lower jaws preserved in the Oxford University Museum and referable to Pliosaurus rossicus (previously referred to Stretosaurus [59] and Liopleurodon), indicated a length of 17 metres (56 ft).
Pliosauridae was formally named by Harry G. Seeley in 1874. [2]Pliosauridae is a stem-based taxon defined in 2010 (and in earlier studies in a similar manner) as "all taxa more closely related to Pliosaurus brachydeirus than to Leptocleidus superstes, Polycotylus latipinnis or Meyerasaurus victor".

The plant-eating dicynodont Lisowicia bojani is the largest-known of all non-mammalian synapsids, at about 4.5 m (15 ft) long, 2.6 m (8 ft 6 in) tall, and 9,000 kg (20,000 lb) in body mass. [ 11 ] [ 12 ] [ 13 ] However, in 2019 its weight was later more reliably estimated by modelling its mass from the estimated total volume of its body.
In 1860, Hermann Trautschold assigned the name Pliosaurus giganteus to a small tooth now thought to pertain to Liopleurodon. However, as the name Pliosaurus giganteus had already been used twice by this point, Trautschold's name is also invalid. [4] [1] The genus name Liopleurodon was coined by Henri Émile Sauvage in 1873.
The largest extant theropod is the common ostrich, up to 2.74 metres (9 ft 0 in) tall and weighs between 63.5 and 145.15 kilograms (140.0 and 320.0 lb). [ 35 ] The smallest non- avialan theropod known from adult specimens may be Anchiornis huxleyi , at 110 grams (3.9 ounces) in weight and 34 centimetres (13 in) in length, [ 36 ] although later ...
Rhomaleosaurus (meaning "strong lizard") is an extinct genus of Early Jurassic (Toarcian age, about 183 to 175.6 million years ago) rhomaleosaurid pliosauroid known from Northamptonshire and from Yorkshire of the United Kingdom.
