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 ...
Plesiosauroidea (/ ˈ p l iː s i ə s ɔːr /; Greek: πλησιος plēsios 'near, close to' and σαυρος sauros 'lizard') is an extinct clade of carnivorous marine reptiles.They have the snake-like longest neck to body ratio of any reptile.
Researchers from Lund University in Sweden have been analyzing the soft tissue from a 183 million-year-old plesiosaur for the first time in history after the fossil was found intact near Holzmaden ...
Thalassiodracon was originally placed in the genus Plesiosaurus. It has been classified in a new genus Thalassiodracon many years later following an examination of a skull. This animal is considered one of the oldest representatives of the group of plesiosaurs, perhaps ancestral to the superfamily of Pliosauroidea (short-necked plesiosaurs). [22]
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 ...
Plesiosaurs were ocean-going reptiles that were contemporaries of the dinosaurs, living from the Late Triassic to the end of the Cretaceous Period. Geology: Prehistoric plesiosaurs were penguins ...
Some marine reptiles, such as ichthyosaurs, plesiosaurs, metriorhynchid thalattosuchians, and mosasaurs became so well adapted to a marine lifestyle that they were incapable of venturing onto land and gave birth in the water. Others, such as sea turtles and saltwater crocodiles, return to shore to lay their eggs.
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.
