Cryptoclididae is a family of medium-sized plesiosaurs that existed from the Middle Jurassic to the Early Cretaceous. They had long necks, broad and short skulls and densely packed teeth. They fed on small soft-bodied preys such as small fish and crustaceans.
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.
Serpentisuchops is a medium-sized plesiosaur, reaching over 7 m (23 ft) in total body length. It is unusual among derived plesiosaurs, as it has both a long snout and long neck. In contrast, elasmosaurids and microcleidids had short snouts and elongated necks, and many pliosaurids and other polycotylids had long snouts and short necks.
Plesioelasmosaurus is an extinct genus of elasmosaurid plesiosaur from the Late Cretaceous (middle Cenomanian) Greenhorn Limestone of Kansas, United States. The genus contains a single species, P. walkeri, known from a partial skeleton. [1]
Rhomaleosauridae is a family of plesiosaurs from the Earliest Jurassic to the latest Middle Jurassic (Hettangian to Callovian stages) of Europe, North America, South America and possibly Asia. Most rhomaleosaurids are known from England , many specifically from lower Blue Lias deposits that date back to the earliest Jurassic , just at the ...
[27] [28] [4] Some specimens may even be 11.7–14.4 metres (38–47 ft) long and are based on a giant mandible and giant neck vertebrae that may be referred to Pliosaurus. [6] [1] Analysis of bones from the four flippers suggest that the animal cruised using just two fore-flippers, using the back pair for extra speed when pursuing and ...
Cryptoclidus was a medium-sized plesiosaur, with the largest individuals measuring up to 4 m (13 ft) long and weighing about 737–756 kg (1,625–1,667 lb). [ 1 ] [ 9 ] The fragile build of the head and teeth preclude any grappling with prey, and suggest a diet of small, soft-bodied animals such as squid and shoaling fish.
Aristonectinae is a subfamily of plesiosaurs in the family Elasmosauridae.It includes the Late Cretaceous plesiosaurs Aristonectes and Kaiwhekea, traditionally grouped with the Late Jurassic Tatenectes and Kimmerosaurus in the family Aristonectidae.
