Albertonectes vanderveldei

Albertonectes is an extinct genus of large plesiosaurs that lived in North America during the Campanian stage of the Late Cretaceous period, at around 73.5 million years ago. The only known species is A. vanderveldei, described in 2012 from an almost complete postcranial skeleton discovered in 2007 near Lethbridge, in the province of Alberta, Canada. Although currently only documented from the holotype, a possible second specimen was discovered in 2015 in the same locality.
