Aristonectes quiriquinensis, sp. nov., a new highly derived elasmosaurid from the upper Maastrichtian of central Chile
(Society of Vertebrate Paleontology, 2014-01)
This paper describes a new species of elasmosaurid plesiosaur, Aristonectes quiriquinensis, sp. nov., based on a partial skeleton recovered from upper Maastrichtian beds of the Quiriquina Formation of central Chile. The ...
Osteology of aristonectes quiriquinensis (elasmosauridae, aristonectinae) from the upper maastrichtian of central Chile
(Taylor & Francis, 2018)
The upper Maastrichtian elasmosaurid plesiosaur Aristonectes quiriquinensis from central Chile is here redescribed following further preparation of the holotype. New cranial characters include a flattened skull with a ...

(Elsevier, 2014-01)
The occurrence of a large gastrolith set associated with a specimen referred to Aristonectes sp. is reported here for the first time. The specimen MLP 89-III-3-1 comes from Seymour Island (Is. Marambio), Antarctic Peninsula, ...
Identification of the first postcranial skeleton of Aristonectes Cabrera (Plesiosauroidea, Elasmosauridae) from the upper Maastrichtian of the south-eastern Pacific, based on a bivariate graphic analysis
(Elsevier, 2013)
Cervical vertebrae of elasmosaurids (Sauropterygia, Plesiosauroidea) have proven to be informative even
at family level. The present paper uses a previously developed methodology based on bivariate graphic
analysis that ...
A giant elasmosaurid (Sauropterygia; Plesiosauria) from Antarctica: New information on elasmosaurid body size diversity and aristonectine evolutionary scenarios
(Elsevier, 2019)
Aristonectines show a highly derived morphology among elasmosaurid plesiosaurs, including some
species with large body size. A new postcranial skeleton is described from the uppermost Maastrichtian
levels of the L opez ...
