Fossil specimens that are contemporary (Callovian-Kimmeridgian) with those from England and France referrable to Liopleurodon are known from Germany. In 2013, Roger Benson and colleagues considered both «L.» macromerus and «L.» rossicus to belong to Pliosaurus. They also considered Liopleurodon to be restricted to the Middle Jurassic. In 2015, Jair Israel Barrientos-Lara and colleagues described two pliosaurid fossils found near the town of Tlaxiaco in Oaxaca, Mexico. They also stated that further study of the taxon was needed to confirm that the supposed differences between L. Pachydeirus were indeed due to individual variation.

After considering Liopleurodon to be a subgenus of Pliosaurus, N. Bogolubov also listed the two genera as distinct in 1912. Johann Andreas Wagner published a description of a large plesiosaur tooth from Bavaria, Germany, in 1852, assigning it to a new species that he named Pliosaurus giganteus. Since the name Pliosaurus giganteus had been used prior to Wagner’s publication, Wagner’s name is invalid due to preoccupation. In 1838, Hermann von Meyer applied the name Ischyrodon meriani to a large tooth from Oxfordian-aged rocks in Fricktal, Switzerland. This tooth lacks identifying characteristics, and therefore it is not clear what it belonged to, although Lambert Beverly Tarlo noted the possibility of it pertaining to Liopleurodon in 1960.
The largest known skull, NHM R3536, about 1.265 m (4.15 ft) long would have belonged to an individual measuring approximately 6.6 m long and weighing 3.3 t (3.6 short tons). In 1905, John Frederick Blake described two teeth from Rushden, England, similar to those of other Liopleurodon ferox specimens, though from older strata than those from Peterborough. He noted that the teeth were quite different from those of Pliosaurus, while the bones were dissimilar to those of Polyptychodon. Since the species couldn’t be assigned to either genus, he recommended reinstating the name Liopleurodon.
Thus, avoidance is the most common form of defense in reptiles. At the first sign of danger, most snakes and lizards crawl away into the undergrowth, and turtles and crocodiles will plunge into water and sink out of sight. Reptiles shed their skin through a process called ecdysis which occurs continuously throughout their lifetime. In particular, younger reptiles tend to shed once every 5–6 weeks while adults shed 3–4 times a year. Younger reptiles shed more because of their rapid growth rate.

And the perfect girl for you might not even be into reptiles. Everyone is entitled to an opinion on pets and breeding animals.

I’ve also not been bitten by a snake but have had to get tetanus shots for rescue kitten bites and scratches, and an African soft fur bit the hell ot of me and I bled everywhere. I’d wager that a ball python bite is far less painful.
One study found that wood turtles were better than white rats at learning to navigate mazes. Another study found that giant tortoises are capable of learning through operant conditioning, visual discrimination and retained learned behaviors with long-term memory. Sea turtles have been regarded as having simple brains, but their flippers are used for a variety of foraging tasks in common with marine mammals. When Sauropsida was used, it often had the same content or even the same definition as Reptilia.
How to Treat Reptiles for Vitamin A Deficiency
The difficulty is that most turtle shells are rigid and do not allow for the type of expansion and contraction that other amniotes use to ventilate their lungs. Some turtles, such as the Indian flapshell , have a sheet of muscle that envelops the lungs. When at rest, the turtle can retract the limbs into the body cavity and force air out of the lungs. When the turtle protracts its limbs, the pressure inside the lungs is reduced, and the turtle can suck air in.
