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 a partial skull (cranium and mandible), the atlas-axis complex, additional cervical vertebrae, caudal vertebrae, an ilium, and limb elements. The basioccipital and atlas intercentrum are pathologically deformed, probably due to an osteomyelitic infection. Two potential autapomorphies were found in…

Lindwurmia, a new genus of Plesiosauria (Reptilia: Sauropterygia) from the earliest Jurassic of Halberstadt, northwest Germany
TLDR
Phylogenetic analyses variably place Lindwurmia as sister taxon to Anningasaura and in a basal position to all other plesiosaurians or recover it among rhomaleosaurids.
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.
The most complete specimen of Kawanectes lafquenianum (Sauropterygia, Plesiosauria): new data on basicranial anatomy and possible sexual dimorphism in elasmosaurids
First record of Kawanectes lafquenianum (Plesiosauria, Elasmosauridae) from the La Colonia Formation of Argentina, with comments on the mandibular morphology of elasmosaurids

A new elasmosaurid plesiosaurian from the Early Cretaceous of Russia marks an early attempt at neck elongation
TLDR
A new elasmosaurid is described from the upper Hauterivian (Lower Cretaceous) of Ulyanovsk (European Russia) and its shape suggests multiple episodes of elongation and shortening, however, the precise patterns are obscured by an unstable phylogenetic signal.
The cranial anatomy and relationships of Cardiocorax mukulu (Plesiosauria: Elasmosauridae) from Bentiaba, Angola
TLDR
A new specimen of the plesiosaur Cardiocorax mukulu is reported that includes the most complete plesioaur skull from sub-Saharan Africa and is returned in an early-branching or intermediate position in Elasmosauridae in four out of the six of the phylogenetic analyses.

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 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…

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.
THE ELASMOSAURID PLESIOSAUR ARISTONECTES CABRERA FROM THE LATEST CRETACEOUS OF SOUTH AMERICA AND ANTARCTICA
TLDR
The dental morphology and peculiar occlusal pattern, forming an interlocking trap, suggest that Aristonectes strained a diet of small, soft organisms from the water.
Braincase of a Polycotylid Plesiosaur (Reptilia: Sauropterygia) from the Upper Cretaceous of Manitoba, Canada
TLDR
A virtual reconstruction of the braincase of a polycotylid plesiosaur referable to Dolichorhynchops from the Niobrara Formation was created by using a three-dimensional scanning technique that produces accurate reconstruction of missing or damaged elements and demonstrates the three- dimensional relationships among the elements.
Two new species of long-necked plesiosaurians (Reptilia: Sauropterygia) from the Upper Jurassic (Middle Volgian) Agardhfjellet Formation of central Spitsbergen
TLDR
The Middle Volgian age of this material helps to bridge the temporal and morphological gap between better known Middle and Late Jurassic plesiosaurians from Europe and Late Cretaceous taxa primarily known from North America.
