The size of Pliosaurus has been debated among paleontologists. Specimens of P. funkei were initially estimated to reach a total body length of 10–13 metres (33–43 ft), with estimated skull lengths of 1.6–2 m (5.2–6.6 ft) for the holotype (PMO 214.135) and 2–2.5 m (6.6–8.2 ft) for the referred specimen (PMO 214.136).

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".

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.
Iguanas vary considerably in size and form, but even the smallest lizards in this family are still quite large. Many sources describe the green iguana ( Iguana iguana ) as the largest iguanid , often reaching lengths up to 1.5 metres (4.91 ft) and masses of 4 kg (8.8 lb), [ 75 ] and with a maximum length of 2 m (6.6 ft) and a mass of 8 kg (18 ...
Lorrainosaurus was a fairly small pliosaur. When extrapolating the length of the holotype's full-length mandible (133 centimeters (52 in)) to the proportions of the closely related Stenorhynchosaurus, which is represented by a near-complete skeleton with a mandible close to one-third of the total animal's length, [a] a total length of 4.66 meters (15.3 ft) for L. keileni can be estimated.
Size comparison. Sachicasaurus was a large pliosaur, with the type specimen measuring approximately 10 metres (33 ft) long and weighing 17 metric tons (19 short tons). [1] [2] The holotype specimen, MP111209-1, was found in 2013 and is known from a near complete skull, and postcranial elements including a complete hindlimb and various vertebrae.
