ABSTRACT A new elasmosaurid plesiosaur, Albertonectes vanderveldei, gen. et sp. nov., is described on the basis of an almost complete postcranial skeleton from the upper Campanian, Bearpaw Formation in Alberta, Canada. The new taxon is distinguished by a unique set of characters—76 cervicals, lateral longitudinal ridge on posterior-most cervicals, relatively wide clavicular arch, tapered ventral projection at the median symphysis of coracoids, pointed anterolateral projection of pubis, fused… 
A New Elasmosaurid (Sauropterygia, Plesiosauria) from the Bearpaw Shale (Late Cretaceous, Maastrichtian) of Montana Demonstrates Multiple Evolutionary Reductions of Neck Length Within Elasmosauridae
ABSTRACT Plesiosauria is a diverse clade of marine reptiles that have been studied since the early 19th century. However, phylogenetic relationships within the group have been contentious due to
A new elasmosaurid (Sauropterygia: Plesiosauria) from the non-marine to paralic Dinosaur Park Formation of southern Alberta, Canada
TLDR
This study reports on a recently collected and prepared specimen, which represents the most complete elasmosaurid yet collected from the DPF, and is sufficiently complete to be assigned as the holotype of a new genus and species.
A New Basal Elasmosaurid (Sauropterygia: Plesiosauria) from the Lower Cretaceous of Germany
ABSTRACT Here we report on a new basal elasmosaurid plesiosaurian, Lagenanectes richterae, gen. et sp. nov., from the Lower Cretaceous (probably Upper Hauterivian) of Germany. The material includes
Postcranium of the paradigm elasmosaurid plesiosaurian Libonectes morgani (Welles, 1949)
TLDR
An examination of character scores used in published plesiosaurian phylogenies concurred with an examination of postcranial elements of Libonectes morgani first-hand, and highlights the persistent significance of post cadaveral elements for discriminating elasmosaurid taxa.
A Small Body Sized Non-Aristonectine Elasmosaurid (Sauropterygia, Plesiosauria) from the Late Cretaceous of Patagonia with Comments on the Relationships of the Patagonian and Antarctic Elasmosaurids
Abstract. The systematics of the Late Cretaceous non-aristonectine elasmosaurids from Argentinean Patagonia are poorly known as there is no valid species currently recognized. Here a new
Reassessment of the Styxosaurus snowii (Williston, 1890) holotype specimen and its implications for elasmosaurid plesiosaurian interrelationships
The holotype (KUVP 1301) of Styxosaurus snowii—one of the earliest described elasmosaurid plesiosaurians—consists of a well-preserved cranium, mandible and articulated sequence of anterior–mid-series

TERMINONATATOR PONTEIXENSIS, A NEW ELASMOSAUR (REPTILIA; SAUROPTERYGIA) FROM THE UPPER CRETACEOUS OF SASKATCHEWAN
Abstract A new elasmosaur, Terminonatator ponteixensis, gen. et sp. nov., from the Upper Campanian Bearpaw Formation of southwestern Saskatchewan, Canada, is one of the youngest plesiosaurs from the
A NEW ELASMOSAURID PLESIOSAUR FROM THE LOWER CRETACEOUS OF QUEENSLAND, AUSTRALIA
TLDR
Cladistic analysis using 43 discrete cranio-dental and vertebral characters coded for 16 ingroup and one outgroup taxon supports this conclusion, indicating that E. carinognathus is a crown-group elasmosaurid of more derived grade than Occitanosaurus (Lower Jurassic, Toarcian, France).

A Cladistic Analysis and Taxonomic Revision of the Plesiosauria (Reptilia: Sauropterygia)
TLDR
The Plesiosauria is found to by polyphyletic due to the inclusion of the Polycotylidae; this second clade is instead a member of the Plesiosauroidea, and thus more closely related to elasmosaurs than to other ‘pliosaurs’.
A phylogeny of Plesiosauria (Sauropterygia) and its bearing on the systematic status of Leptocleidus Andrews, 1922
TLDR
A cladistic analysis including Leptocleidus and a new, apparently morphologically similar specimen from Alberta, was undertaken to assess their phylogenetic position within Plesiosauria, and results indicate a basal dichotomous split into the traditionally recognized pliosauroidea and plesiosauroid clades.
PRELIMINARY DESCRIPTION AND PHYLOGENETIC POSITION OF A NEW PLESIOSAUR (REPTILIA: SAUROPTERYGIA) FROM THE TOARCIAN OF HOLZMADEN, GERMANY
TLDR
A phylogenetic analysis places Plesiopterys as the sister group of the Plesiosauroidea, and as such the taxon is the most basal taxon yet known on the branch leading to this major clade.
