A worn juvenile plesiosaur vertebra from an indeterminate elasmosaurid, possibly an aristonectine from the Kristianstad Basin in the Skåne Province of Sweden. These specimens from this deposit are often referred to the nomen dubium, Scanisaurus cf. nazarowi. Thanks to Dr. Benjamin P. Kear and Sven Sachs for helping confirming the plesiosaurian nature of the vertebra.

Elasmosaurus platyurus, one of the most famous plesiosaurs, well known for its ungodly long neck.

With Hatsune Miku for scale:

Lagenanectes

Lagenanectes — рід еласмозаврових плезіозаврів з нижньої крейди, знайдений у Нижній Саксонії, Німеччина. Єдиний вид, Lagenanectes richterae, був вперше описаний у 2017 році і вважається одним з найкраще збережених скам’янілостей плезіозаврів цього геологічного періоду в Європі.

Styxosaurus snowii here was one of the largest known elasmosaurids, named after the mythological river separating the worlds of the living and the dead.

Reaching around 11m long (36'), with half of that being entirely neck, it lived during the late Cretaceous period about 83-80 million years ago in what is now the American Midwest – a region that at the time was submerged under a large inland sea.

With pointy interlocking teeth in its proportionally tiny head, Styxosaurus would have fed on slippery aquatic animals like fish and cephalopods, possibly using its long neck to get up close to its targets while the bulk of its body remained out of sight in dark murky waters. Large numbers of gastroliths found in the stomach regions of some specimens would have been used to grind up the hard parts of prey items after they were swallowed whole.

95 million years ago, in a shallow sea dividing what is now North America, an Enchodus gets caught by a hungry Thalassomedon.

Our next dinosaur is another marine animal as well :3 This is a Thallasmedon. One of the BIGGEST elasmosaurids to ever exist. (As you can see I love elasmosaurids very much lol.) The thallasmedon lived just under 99.3 to 93.5 million years ago! Its scientific name means Sea Lord which I think is really funny. It was 36 in length (however there have been bones found believed to be 40 feet in length!) it falls under the classification of Elasmosauriadae. (Wink wink.) It was living around the later period of the Cretaceous period and the Cenomanian period. It’s the closest relative is also believed to be what scientists seem to be the closest replica or being to that of an Elasmosaur (Wink wink wink). 

The thallasmedon was thought to have swum in the Western Interior Seaway which is the Cretaceous sea that divided the two halves of North America. (Cited here: http://www.prehistoric-wildlife.com/species/t/thalassomedon.html) 

Fun Fact: Thallasmedon had 62 vertebrae in their neck. Imagine food going down that...must be like a rollercoaster in there lol. Wonder how their blood circulated over the distance...
