Life restoration of Albertonectes vanderveldei. Based on Figure 2 of "Albertonectes vanderveldei, a new elasmosaur (Reptilia, Sauropterygia) from the Upper Cretaceous of Alberta" by Tai Kubo, Mark T. Mitchell, and Donald M. Henderson (Journal of Vertebrate Paleontology 32(3): 557-572).
Their neck was larger than other types of plesiosaurs at around 23 feet long, making up more than half their total body length which was 38 feet long in size.
Albertonectes
The Albertonectes were first discovered by accident by a fossil company called Korite International which was looking for gem-quality ammonite shells.
