Letter concerning the discovery of the 1823 Plesiosaurus, from Mary Anning. This timeline of plesiosaur research is a chronologically ordered list of important fossil discoveries, controversies of interpretation, taxonomic revisions, and cultural portrayals of plesiosaurs, an order of marine reptiles that flourished during the Mesozoic Era.
Plesiosaurus was a moderately sized plesiosaur that grew to 2.87–3.5 m (9.4–11.5 ft) in length. [ 13 ] [ 14 ] There are approximately 40 cervical vertebrae (neck vertebrae), with different specimens preserving 38 to 42 cervical vertebrae. [ 15 ]
The fact that the osteology of the plesiosaur's neck makes it absolutely safe to say that the plesiosaur could not lift its head like a swan out of water as the Loch Ness monster does, the assumption that air-breathing animals would be easy to see whenever they appear at the surface to breathe, [146] the fact that the loch is too small and ...
Elasmosaurus differed from all other plesiosaurs by having 72 neck vertebrae; more may have been present but were later lost to erosion or after excavation. Only Albertonectes had more neck vertebrae, 76, and the two are the only plesiosaurs with a count higher than 70; more than 60 vertebrae is very derived (or "advanced") for plesiosaurs. [14 ...

“Sunrise on the Reaping” is the fifth “Hunger Games” installment, revisiting Panem 24 years before the first book's events. The prequel begins on the reaping of the 50th Hunger Games ...
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.
They were part of Sauropterygia, the group that includes plesiosaurs. Placodonts were generally between 1 and 2 m (3 ft 3 in and 6 ft 7 in) in length, with some of the largest measuring 3 m (9.8 ft) long. The first specimen was discovered in 1830. They have been found throughout central Europe, North Africa, the Middle East and China.
